Our Ecosystems : Forests!

Of course, we need to plant native trees... But we need to understand that there is more to forests than just a massive collection of trees. It is a natural, complex ecosystem, made up of a wide variety of trees, which support a massive range of life forms. Apart from trees, forests also include the soils that support the trees, the water bodies that run through them and even the atmosphere or air around them. Forests of the world are a natural wonder that we, humans, have sadly taken for granted.

Environmental activists consider forests as one of the top 5 natural resources on Earth. This is rightly so, its high time why we should immediately stop its' destruction.

Forests are hugely important for life on Earth. This is because it serves as an ecosystem and sustains life for millions of animals, birds and aquafauna that live in the rivers & streams running through these forests…Biodiversity! Forests serve two important roles viz. Productive role and Protective role. While we all know about the products like Food, Shelter, Clothing, Fuel and Timber that we get from forests along with Non-timber Forest Products; we often take granted their priceless protective services. 

Climate Improvement

Forest increase local precipitation by about 5 to 10% due to their aerographic and microclimatic effect and create conditions favourable for the condensation of clouds. Forests reduce temperature and increase humidity. It also reduces evaporation losses. Forests form an effective sink for the carbon dioxide produced as a result of animal respiration, burning of fossil fuels, volcanoes and other natural & human-induced activities. And if that is not all, a by-product of photosynthesis is oxygen.

Forests play a significant role in maintaining the CO2 balance in the atmosphere and purifying the air.

Trees and soils help regulate atmospheric temperatures through a process called evapotranspiration. This helps to stabilize the climate.

Soil and water conservation

Forests maintain the productivity of the soil through adding a large quantity of organic matter and recycling of nutrients. The leaves are used as manure. Tree crowns reduce the attack of rain and check splash erosion. Forests increase the infiltration and water holding capacity of the soil, resulting in much lower surface runoff. This in turn results in checking of soil erosion.

Forest checks floods too! Forests intercept 15 to 30% of the floods caused due to siltation of river channels & irrigation resources caused due to erosion. Forests and trees reduce wind velocity considerably, which causes considerable reduction in wind erosion; checks shifting of sand dunes and halts the process of desertification. Rapid siltation of various reservoirs in the country is the result of deforestation in the catchment areas of these reservoirs.

Forest protect us from physical, chemical and noise pollution, dust and other particulates and gaseous pollutants cause serious health problems. Forests protect as from these pollutants. Forest and trees provide shelter and wind break effect which is beneficial to agricultural crops, particularly in arid and semiarid areas and increase agricultural production.

Watershed

Forests serve as a watershed…the area of land that contributes water to a stream or river. Almost all water that flows in rivers & lakes ultimately comes from forest-derived water tables.

Wildlife Habitat and Ecosystems

Forests serve as a habitat to millions of animals. Animals form part of the food chain in the forests. All these different animals and plants are called biodiversity, and the interaction with one another and with their physical environment is what we call an ecosystem. Healthy ecosystems can better withstand and recover from a variety of disasters such as floods and wildfires.

Forests and biodiversity are the key to all life forms. The richer the diversity of life, the greater the opportunity for medical discoveries, economic development and adaptive responses to such new challenges as climate change. Uses of genetic diversity within forests enable the development of new medicines; progress in health care and science.

Looking at the importance of forests and trees, You can deduce the massive effects of deforestation and tree-cutting activities… Soil erosion, Disturbed Water Cycle, Loss of Biodiversity, Climate Change etc. But what we can not see or relate to is Loss of livelihoods of the people directly depending on the forests and loss of lives due to effects of deforestation like droughts, floods, human animal conflict, invasive dominance of a particular species.

Close to one billion hectares (2.5 billion acres) globally is estimated to be available for some kind of forest restoration. If only it were that simple.

So how to regrow a forest? : Get out of the way.

According to International Union for Conservation of Nature (IUCN), the best thing we can do to regrow a natural forest is to stop interfering in the forest ecosystem. The nature will take care of the rest.

One needs to understand the types and importance of forests, the problem of deforestation and it's effects, as well as what we can do to minimize the consequences. Sometimes, we are overwhelmed by the extent of damage humans have caused, and we are not sure if an individual can make an impact.

Yes, you can!

There are millions of people just like you, who are learning about the issue and taking little steps to help. Additionally, many governments, organizations, and societies are making great strides in helping reducing deforestation.

But there is still a lot to do. On the 14th anniversary of Gifting Trees, let us discuss a few things you can also do to help...

Make a conscious effort to share information with friends and family members on deforestation and its' effects. Things work better when responsible people don’t give up. Stand up for what you believe in!

Reduce the use of artificial items, recycle more and re-use items. Wood, paper, plastics and many other things we use every day at home can be linked to natural resources being destroyed. This means that if we all recycle more, there will be less dependence on the environment (and forests).

Allowing degraded natural forests to re-grow is a more effective, immediate and low-cost method for removing and storing atmospheric carbon than planting new trees.

These forest ecosystems - the result of ecological and evolutionary processes and their natural patterns of distribution and abundance of plants and wildlife have greater resilience to external shocks. They can adapt to changing conditions and store more stable natural carbon stocks than young, degraded or plantation forests. Nowadays, Miyawaki forests have gained widespread attention as a promising approach to reforestation and biodiversity restoration. However, these newly planted forests(?) can not even match the natural forests, let alone be the substitute for them. Yes, trees must be planted & grown in urban settlements and industrial areas. But PLANTING TREES IS NO SUBSTITUTE FOR NATURAL FORESTS..! Remember, "One can plant trees, but can not plant a forest!" 

Growing existing natural forests to maturity optimizes their biological sequestration potential to remove carbon dioxide from the atmosphere. As well as maximizing cost-effective and natural carbon sequestration, proforestation also provides other benefits such as clean water supply from filtration by tree roots. But the natural forests must grow naturally and not by introducing artificial plantations in a natural forest. Introducing non-native species and altering forest type or topography could disrupt existing ecosystems and ecological processes, potentially leading to unintended consequences.

Indigenous vs. Introduced Plants : The Ongoing Debate

Few months ago, I stumbled upon an article written by a representative of an ecological restoration firm that has been promoting native plant species for the past decade. The article sparked controversy by suggesting that non-native tree species need not be shunned altogether. Though the statement was not completely wrong, that article raised eye-brows of many nature-lovers as the statement was contradicting the very soul of that organization. 

So how do you decide what kind of tree to plant? Or perhaps, have you wondered, while walking down a city street or strolling through a park, why did we choose to plant a row of non-native Gulmohor or Rain-trees, instead of trees native to our region? This post aims to provide clarity on this topic by exploring the various factors that influence our tree-planting choices. 

At present, there is a debate on whether to plant indigenous trees or introduced/alien trees. Some favor indigenous native trees while others do not seem to bother about the species. But this debate should be considered from an environmental standpoint.

Different plants thrive in different regions of our country according to the nutrients, climate and habitat. These plants and the wildlife that depend on them create a rich ecosystem, and the introduction of an alien plants into this delicate balance is a matter of ongoing debate. Some say that many introduced shrubs, vines & trees that are naturalised in India, are useful. The examples include guava, custard-apple, grapes, sugarcane etc. But it should be noted here that all these plants are grown agriculturally, where their spread is controlled, carefully maintained. Furthermore, not all introduced plants are non-invasive or benign to the ecosystem.

Proponents of introduced trees argue that they provide shade, oxygen, and visual appeal through their colorful flowers. However, the problem arises when a single introduced tree species outcompetes ten native trees, leading to a tenfold reduction in carbon dioxide absorption and shade. Additionally, habitat loss for birds and pollinators can have devastating impacts on the ecosystem. Introduced species are often free from natural predators & pests, which makes them prone to becoming invasive, out-competing native flora for water and soil. This in turn drives away biodiversity and reduces the chances available for native species, leading to biological pollution. Introduced plants are often short-lived and brittle, making them susceptible to uprooting during storms. The leaves of trees like Eucalyptus and Mangium do not decompose easily and do not contribute to the production of organic fertilizer, resulting in soil pollution. 

While introduced trees like Gulmohar, Copperpod, Jacaranda and Spathodea may look beautiful, their ecological value is negligible. Although a few species of birds may perch on these trees, and pollinators like bees may occasionally be seen on their flowers due to a lack of other flowering species, it would be foolish to conclude that introduced species attract birds and pollinators. Many state governments have banned the cultivation of Eucalyptus due to the large amount of water it absorbs from the soil, which can exacerbate water scarcity issues in certain areas. Introduced species like Gliricidia, Mangium (Acacia Mangium), Earleaf Acacia (Acacia Auriculiformis) and Mesquite (Prosopis Juliflora) were brought to India from Australia and Mexico for rapid reforestation, timber, and fuelwood purposes. However, these same plants have now become a serious threat to ecosystems, competing with indigenous flora and fauna and disrupting nutrient cycling and hydrology. This impacts the overall economic stability of local communities and human health. Many of these species have aggressive root systems or produce a large number of viable seeds, both of which allow the plants to quickly invade the soils outside their growing areas. This resulted in almost destruction of the native Babool (Acacia Nilotica, or recently known as Vachellia Nilotica), which is an important tree species if dry regions. 

Trees native to a particular region have evolved to thrive in specific soil types, rainfall patterns, light availability, seed dispersal mechanisms, and other environmental attributes. In their native environment, these trees may provide cover, food, and habitat for birds, amphibians, insects, and mammals. The tree species that have been living in India for centuries and providing benefits not only to humans but also to wildlife and the ecosystem deserve priority. In fact, there are several fast-growing native trees in India that bear beautiful flowers. Native trees are more adaptable to their growing conditions and more resistant to disease than alien species that have only been introduced in recent decades. You can find the list of native trees here.

Several gardening enthusiasts and nature-lovers derive satisfaction from cultivating rare and uncommon plant species, which are not easily found in their vicinity. In fact, the introduction of new plants is a celebrated activity which delights many gardeners, and attracts media attention. These practices have contributed to scarcity of our own important native species in the urban areas across India. Sadly, it is now increasingly challenging to come across trees like Palash, Sita-Ashok or Kaim in the gardens of many cities. 

In conclusion, it is important to understand the impact of the trees we plant in our region. While non-native species may be visually appealing, they can have negative impacts on the local ecosystem. On the other hand, native trees have evolved to thrive in their environment and provide important benefits to both humans and wildlife. By prioritizing the plantation of native trees, we can promote a healthier and more diverse ecosystem while also supporting the local economy and preserving our cultural heritage. Though there is no need to hate the previously planted and grown non-native trees; at least now onwards, the plantation of any alien or foreign plant must be strongly discouraged. 

Today is 13th anniversary of Gifting Trees... Come, let us all take responsibility to protect our environment and choose the right kind of trees to plant for a sustainable future!

This Summer, Care for Trees?!

Just as we all are troubled by record-breaking temperatures every year, can you even imagine the sufferings of the trees and vegetation in our surroundings? Hot & dry summers can have an impact on your trees, especially when they are young and growing.

Based on NOAA's global analysis, the 10 warmest years on record have all occurred since 2005, and 7 of the 10 have occurred just since 2014. 2020 was the second-warmest year on record based on NOAA’s temperature data, and land areas were record warm.

Similar to the humans who find themselves lethargic and lifeless during these hottest summers, when water is scarce, the saplings you had planted last year also tend to deteriorate. Or when not taken care of in extreme conditions, die. 

At times like these, human intervention is key to helping your trees grow up healthy. Here are a few suggestions or tips which may help in protecting the saplings and young plants you love...

1. Mulch, a fresh layer!

Applying mulch provides some much-needed help for saplings, especially around the root area. Proper application of mulch is a good way to help young trees take in more water and set down strong root systems. Sufficient mulch of about 2 inches thick will not only retain the moisture, but also discourage the growth of weeds. Just do leave some space between the mulch and the base of the sapling.

2. Protect from direct sunlight

A shade net or any cloth for that matter can prevent your young sapling from harsh sunlight in the soaring heat. Shade cloth does not provide complete shade, but improves the diffusion of light and provides ventilation for the plants.

The cloth must be well-supported by 3-4 strong sticks or bamboo so as to act as a windbreak also. The sticks need to be inserted enough into the soil so that they stand strong against the winds. Then a shade cloth can be tied to these sticks in such a way that the plant receives sufficient sunlight, but harsh rays are blocked. Do make sure the plant growth should not be obstructed by the cloth. 

3. Water the plant!

Water the plants early in the morning or late evening when the temperature is not that high. Focus on the root zone to maximize the amount of water they get each time. Knowing how to water your plants properly should be your priority during the summer.

You may try keeping a perforated plastic bottle underground, which you fill every time. This, over a period of time, allows water to seep deeper into the ground, which encourages deeper root growth. 

4. Care of the soil

Soil is a vital part of the natural environment. It’s always better to check the surrounding soil of your plants. When the soil is extremely compact, it prevents the tree from getting the water and nutrients it needs. When the soil is sandy, it can not hold moisture and nutrients. The soil must be a good mix of these both impregnated with mulch so that earthworms can flourish in it. 

5. Watch out for signs of heat stress

Keep a sharp eye out for heat stress on particularly hot days. Common signs include drooping and wilting of the leaves. In case of heat stress, give your tree sufficient water to help it recover. 

A young plant must be taken care of during its first 3-5 years. Then it's just a piece of cake! We are doing the same and shall continue to do that. Today is the 12th anniversary of Gifting Trees... I think we have just begun!

The Black Ebony Tree

Here is the tree which is described in a perfect manner by its name. The generic name is derived from greek word dios which means ‘divine’, and pyros meaning ‘fruit’, referring to the excellent fruit of the genus. The specific name melanoxylon means ‘dark wood’. The Tendu (Diospyros Melanoxylon/टेंभूर्णी, टेमरू, तेंदू) is medium-sized handsome tree, which is also known as Black Ebony. Its small flowers appear from April to June on new shoots.

Tendu, though a minor forest produce (MFP) in Central India, is very underutilized tree. The most economically significant use of this species is that its leaves are used to roll bidis (an indigenous traditional cigarette, which uses the kendu leaf for rolling instead of paper). The leaves possess unrivalled qualities of flavour, colour, flexible and leathery texture, decay resistance and easy workability, which make them admirably suitable for wrapping bidis.

However, most of the harvest goes waste as the fruit has never been explored for its nutritional aspects. This lesser known fruit is edible & is delicious too! Once fully ripen, the yellow pulp is soft & has a pleasant and sweet taste.

Tendu is a seasonal fruit available mainly in summer. The fruit ripening takes almost a year. These edible fruits are largely eaten & disseminated by birds, notably hornbills. The tree produces good seed in alternate years. The fruits and powdered seeds are sold in local markets and eaten. 

The tree is deciduous or evergreen depending on its habitat. In a dry locality, it is leafless for a short time in the hot weather, regaining its leaves in May-June. In a moist locality, it is evergreen. Though the tree has small flowers, the tree is regularly visited by insects and butterflies. It is the larval host plant for the Symphaedra nais & Spindasis vulcanus butterflies.

The tree has been revered in Ayurvedic medicine. The seeds have been prescribed as a cure for mental disorders, nervous breakdowns and palpitations of the heart. The fruits have a cooling and an astringent effect. Dried flowers are reportedly useful in urinary, skin and blood diseases. The bark is astringent; its decoction is used in diarrhoea. Its regeneration is through seeds, cuttings and root suckers. Soaking seeds for about 12 hours in cold water improves germination. Stump planting has been found to be as good as direct seeding. 

Tendu is the most widely distributed and tolerant species when considered to soil requirements. It grows on poor denuded soils, hot and dry hill slopes, stony soils and also heavy clays. It demands light; it is drought and frost hardy but sensitive to water-logging. It is coppiceable & tolerance to pruning makes it a good fodder tree. The tree also pollards well, although the growth of the pollard shoots is slow. Its cultivation on field boundaries or distributed in field crops, such as oilseed and cereal crops, appears to be a feasible and attractive proposition. Its deep tap-rooting habit would minimize competition with annual crops. It gives good quality charcoal. 

The fruit tree being rich in nutritional, medicinal and processing qualities can play a very significant & vital role in the livelihood security of the rural communities through enhanced household income, employment generation and environmental protection. Tendu fruits have a great potential for commercial cultivation. In fact, plantation of Tendu tree along with other local fruits of our region like Ber, should be done in city gardens and residential areas.

The Complete Elm!

Indian Elm (Holoptelea Integrifolia/वावळ, पापडी) is a large deciduous, fast-growing tree with good canopy. It is densely foliated tree. Though its tiny flowers are not conspicuous, the circular samara fruits give an attractive appearance to the tree; also making the tree easy to spot. It has wind-pollinated male and hermaphrodite flowers. The flowers are small, greenish-yellow to brownish & pubescent.

Indian Elm tree flowers in January-February months and it fruits from March to May. During this period, the tree attracts loads bees and butterflies. It is the larval host plant for the Chilades Pandava butterfly. The fruits of Indian Elm, just like figs, are largely eaten by Langurs. The leaves are used as animal fodder. It can be coppiced. The unripe fruits are edible. Fruits also serve as a good source of Essential oils. This Elm gives good quality charcoal. 

Though Indian Elm grows slowly in initial stages, once established, the species can be fast-growing. It propagates from seeds & cuttings. The papery fruits can be just sprinkled on soil and regular water-spraying helps in their germination. It is resistant to gaseous pollutants. The tree is known to purify air by trapping dust & particulate pollutants. 

The tree is mentioned in Charaka-Samhita, Sushruta-Samhita and other traditional systems. It pacifies vitilated kapha and is known to be useful in skin diseases, haemorrhoids, colic, flatulence & vomiting. Its leaves are also used for diabetes, leprosy & baldness. This herb is also mentioned for the treatment of localized swelling, nausea, indigestion, rheumatism, ringworm infectin, scabies, ulcers and acts as blood purifier. The tree has also been found to have some antibacterial properties. Name the disease and this elm have remedy for that! It is commonly called Chirabilva in Ayurveda. 

Indian Elm is also used in ecological forestry for its heat & drought tolerance and regenerative abilities. It’s a very hardy tree that survives well in the extreme climate. Its root system helps in erosion control of soil and dune stabilization. The leaves also provide useful mulch in good quantity. It’s crushed leaves & bark has a characteristic smell. This virtue makes the tree resistant to pest and these parts can also be used as a pest repellent.

The tree is harvested from the wild for local use as a medicine, food, and as a source of oil and wood. The attractively dense tree is commonly spotted on roadsides across the city and in gardens as well. 

The Grewias

The tree is known for a refreshing drink prepared from the fruits, commonly known as Phalsa Sherbet or squash, is considered a delicacy throughout the hot summer months in India. The Phalsa tree (Grewia Asiatica/फालसा) is a small-to-moderate sized deciduous tree.

Phalsa is a beautiful tree with small orange-yellow flowers, borne in densely crowded axillary cymes. The ripe fruits are eaten as a dessert. Their taste and flavor are very much liked. Due to fruits, the tree is often found pollarded to keep its branches low and within reach.

According to Ayurveda, different parts of this plant possess different pharmacological properties. Leaves have antimicrobial, anticancer, antiplatelet and antiemetic activities; fruit possess anticancer, antioxidant, radio-protective and anti-hyperglycemic properties; while stem bark possesses analgesic and anti-inflammatory activities. The fruits are a cooling tonic, astringent & aphrodisiac; they allay thirst & burning sensations, remove biliousness, cure inflammation, heart & blood disorders and fevers. The fruit is also good against throat trouble. The bark is used as a demulcent, febrifuge and treatment for diarrhea. It cures urinary troubles and relieves burning sensation. The root bark is employed in treating rheumatism. The leaves are applied on skin eruptions and they are known to have antibiotic action.

The tree improves the soil and also aids in reclamation of degraded land. It has been proved that the plantations of Phalsa increased organic Carbon, available Nitrogen, Phosphorus & Potassium in the soil and reduced Calcium Carbonate, pH & bulk density due to litter production greater than that of other fruit trees. It is propagated easily by seeds.

Phalsa can be grown on a wide range of soils, even those that are slightly alkaline, clay or sandy soils. But for fruit production, ideal is a rich alluvial soil. The tree grows in both tropical and subtropical climates but will tolerate other climates, except at high altitude; however, it does best in regions having distinct summer and winter seasons. It is very hardy, drought-tolerant species and capable of existing under severe conditions and is suitable for arid regions.

The fresh leaves are valued as fodder. The mucilaginous extract from the tree obtained after pounding in water is used to clarify sugarcane juice during the preparation of gur, the traditional brown sugar made in India. Ropes or cordage can also be obtained from the tree. Furthermore, there is no serious pest or disease of this species.

There is a similar close cousin of Phalsa from the same genus, the Dhaman (Grewia Tiliifolia/धामण, धामनी) is a moderate-sized deciduous tree.

The yellow flower resembles the Phalsa flower very much. The main difference is in the leaves. The leaves of Dhaman are oblique heart-shaped.

The tree is harvested from the wild for local use of its fibre and edible fruit. The black, globose, 2-3 lobed fruit is about the size of a pea, having a nice flavor. Fruit is a good source of micronutrients such as anthocyanins, phenols, flavonoids and vitamin C. They have a moderate antioxidant activity and make an excellent, healthful addition to the diet.

Dhaman grows rapidly in full sun and light shade. It is successful in a range of well-drained soils. It also serves as a larval host plant for the Coladenia Indrani species of butterflies. It is also propagated by seeds.

The tree has numerous medicinal properties. It is employed in dysentery & applied externally to remove irritation from itch. It also has emetic properties. Leaves and twigs are lopped for fodder. The leaves contain 1% tannin and are sometimes employed as a soap substitute for washing hair. 

Sandpaper Raisin or Rough-leaved Raisin (Grewia Flavescens/खटखटी) is a large shrub or small tree, with beautifully bright yellow flowers. It is multi-stemmed and densely branched, forming a very irregular leafy canopy. Leaves are simple, alternate, hairy and light green on both sides, being more hairy underneath; with irregularly toothed edges. The fruit is berry-like and hard. The skin of the fruit is said to be the hardest amongst the Grewia species. The fruit are eaten by birds, especially hornbills, and also by monkeys. 

The species is also known for its ornamental value and is used as a vegetable, fodder and to make baskets. The fruits are used as food and for traditional medicinal treatments.

The fruits of Grewias attracts many birds and is also consumed by monkeys and antelopes. Leaves are food plants for the larvae of moth-like Skipper butterflies. The trees also serve as important pollinators, food source for many animals and provide a good support for the ecosystem. These species have high potential in agroforestry practices as well as have high ornamental value. Hence it is great have one of these beauties near house!

The Rosewoods

There is a tree which is often mistaken for Indian Rosewood due to striking similarity in their leaves and flowers. But can be distinguished by somewhat darker bark.

Black Rosewood (Dalbergia Latifolia/काळा शिसम, काळारुख) is moderate-to-large sized tree with a dome shaped crown of lush green foliage. The leaves of Shisham have pointing tip whereas the leaves of this species are blunt and broadly rounded with wavy margins. The broad leaves explains the species name latifolia.

Furthermore, though it sheds its leaves, it can hardly be found leafless. It flowers abundantly in aromatic clusters of white colour creating an eye-soothing view. Due to these reasons, it is noted to attract number of birds, butterflies, insects and wildlife. Hence the tree needs to be introduced in home gardens in urban societies. 

Practically, Black Rosewood is quite similar to Shisham, including their use in agroforestry, apiculture, medicines, ornamental or soil improvement. It is also a Nitrogen-fixing tree and gives the nitrogen-rich foliage which is widely used as a green manure and fodder. Like other member of the genus Dalbergia, its honey is dark amber and strong flavoured.

In a drier habitat, the hardy tree is leafless for couple of months, regaining its leaves in April-May. In a moist locality, it is evergreen throughout the year. The species grows on a variety of soils. It grows best on well-drained, deep, moist soils & black cotton soils. The root system of the tree is well developed with deep tap roots and long lateral roots. It reproduces by seed, root sucker or cuttings. Although no treatment is necessary, soaking seed in cool water for 12-24 hours will hasten germination of seeds. 

Black Rosewood is widely used for reforestation of eroded soils. It is also planted as a roadside tree and shade tree. It acts as a soil improver. The leaf litter decomposes slowly releasing nutrients gradually and it is used as mulch. Medicines are made from the tannins in the bark, for diarrhoea, worms, indigestion, and leprosy. These tannins also produce an appetizer.

There is another species from the same genus, Dhobin or Phansi (Dalbergia Lanceolaria subsp. Paniculata/धोबीन, फणशी, दोंडूस) is a very conspicuous and handsome, deciduous tree. It is eye as well as ear catching tree when profusely covered with flowers and young leaves. The tree is actually loud with the buzzing of thousands of bees. Its flowers are white & fragrant.

This species is a moderately fast growing tree. It is recommended for reforestation projects on degraded land where seeds are unlikely to grow successfully. It is propagated by seeds. Young seedlings grow well in the dappled shade of the forest, but they become more light-demanding as they grow older. 

Different parts of trees particularly seed and bark are used in the Ayurveda; mainly to treat arthritic infections and inflammations.

The lesser known tree species has a great potential in Agroforestry. Dhobin has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby. In  other uses, it is used as wind  break for micro-climate enhancement, nectar source for honeybees, and in addition to these leaves are used as a fodder for livestock animals. 

Both these Rosewoods are excellent choice for farmers as well as city dwellers!

Dridhataru...The Robust Tree!

The Button tree or Dhok (Anogeissus Pendula/धोककाळा धावडा) is a beautiful, moderate-sized species. With or without flowers, the tree is known for grace and beauty of its silky foliage. In winters before falling, the leaves turn a beautiful yellowish red. Every time you visit the tree, it appears surprisingly different!

Dhok is often confused with well-known Dhvada tree or rather, is recognized as Dhavda. It has variable bark. Dhok has tiny fragrant flowers in dense clusters. It is a dominant species on sloppy & rocky soils, as nothing else can survive there. It coppices & pollards well and the coppice shoots are fairly fast growing, although the tree grows slowly. It fruits abundantly but has low germination rate. 

Despite having such a low regeneration capacity and a very tough growing conditions, the tree does something spectacular to regenerate. Mr. Pradip Krishen, the writer & environmentalist, finds the tree very unique and pretty. Under the soil surface, a tree sends out a horizontal stem, called a ‘stolon’ and from the end, a sapling roots. Such stems extend in every direction, spawning a colony of genetically identical trees. “It’s like the trees are holding hands. Button tree is more like a Banyan, which instead of sending aerial roots down, sends subterranean shoots up.” says Krishen. 

Dhok is a very important tree species of the fragile eco-systems. It is a drought hardy plant that yields excellent animal fodder and other products like green dye and tannins. The tree is also known for many medicinal properties and has uses for ailments like dysentery, gastric disorders, skin problems, cough or for its anti-oxidant properties. 

It has ecological significance for the Aravalli range and other hilly areas of the country, where it is difficult for other tree species to thrive. It is a hardy tree that can survive even in the extreme conditions.

Axlewood tree or Dhavda (Anogeissus Latifolia/धावडा, धव) is a similar beautiful species from same genus. It is a medium-to-large sized, deciduous tree.

It is one of the most useful multi-purpose trees in India. Axlewood also has tiny beautiful fragrant flowers in dense clusters. But flowerless tree is also equally attractive, mainly due to the bark. Its bark surface is smooth or with scales, pale to dark gray and is mottled in a characteristic pattern. It has somewhat similar flowers and fruits as that of Dhok. Leaves are nearly opposite on drooping branches. 

The drought tolerant tree is also fire-resistant, but does not tolerate water-logging. It is found on a variety of soils, but prefers deep alluvial soils. The tree’s robust nature gives it the Sanskrit name Dridhataru! :)

It is usually mentioned as a possible agroforestry species. Tussar silkworms are fed on its foliage, which is also used as fodder for cattle and buffaloes. Its flowers are an important pollen source for bees. The tree is a good survivor on eroded land. It is often used for river bank stabilization. The tree improves the quality of soil wherever planted. Axlewood tree contributes to soil nutrient cycle by exhibiting high leaf-litter decomposition rates. Its leaves contain large amounts of tannin. The tree is the source of Indian gum, also known as Ghatti gum. Ghatti gum is a good substitute for Gum-arabic and is used in printing, for confectioneries, in dye processes and as a binding agent in pharma industries. It also gives good quality charcoal.

Medicinally, the plant root pacifies vitiated kapha, vata and abdominal disorders. The bark cures vitiated conditions of kapha and vata, wounds and ulcers, inflammations, diabetes, haemorrhages, haemoptysis, diarrhoea, dysentery, haemorrhoids, skin diseases, liver diseases and general debility. Also it is reported to be used in treating snake bites and scorpion stings in India.

Axlewood can be propagated by seeds and coppices. The seeds are soaked in cold water for about 48 hours or 3-min hot water treatment is done for successful germination. The tree produces root suckers, coppices and pollards well.

Both these trees deserve far more attention as an ornamental and ecologically important trees. May be that's why these trees got their place on the 11th anniversary of Gifting Trees...! :-)

The Spectacular Tree!

The Kydia (Kydia Calycina/वारंग, वरंग, रानभेंडी) is rapidly growing, deciduous tree. This beautiful tree flowers when very few native trees are in bloom, that is after rains. And after flowering season also, it continues to look attractive for many months while it’s the rusty fruit ripen and dry out. 

The tree flowers profusely with small flowers which occur in axillary or terminal panicles. Flowers are fragrant and creamish white, greenish white or pink coloured which itself is a delight to watch.

Kydia grows on wide range of habitats, including arid regions. It is often grown as an ornamental species. It is a small to moderate sized deciduous tree. Though deciduous, one may hardly notice a leaf-less tree. Dark green foliage is present throughout the year giving dense shade. The leaf blade is nearly round, usually palmate 3-5-lobed. 

It is propagated by seeds, root suckers or cuttings. It coppices well. Leaves can be used as fodder. The wood is used as fuel and for making charcoal. The tree is valued for the leaves which are lopped for fodder. In the wild, leaves are eaten by the elephants, sambar, deer and bison. The wood is a good source of commercial potash. The young bark is mucilaginous and cold infusion of it is used for clarifying sugarcane juice. The tree is harvested from the wild for its fibre, which is used locally to make coarse ropes. Due to profuse flowering, Kydia flowers during September-October. It attracts number of bees, butterflies, insects and birds during this period having a significant role to play in Apiculture. Bees visiting the tree tend to produce thick and sweet honey. 

Medicinally, the parts of Kydia tree are known to have the analgesic and anti-inflammatory properties. It is often utilised as shade tree or windbreak. The tree is also valued for erosion control. Being such a spectacular tree, it should be planted in gardens, along the roads and societies due its ornamental properties. 

The Yellow Teak

Haldu (Haldina Cordifolia/हळदू, हेदू, गिरिकदंब) is a deciduous tall tree with a large crown and is the sole species in the genus Haldina. The tree has long, straight, clean bole and is often buttressed & fluted at the base. The buttresses are sometimes of irregular and fantastic shapes. When growing in more isolated positions it produces a thick bole and massive branches with a large spreading crown.

Leaves are opposite, broadly ovate, heart shaped glossy green in colour. Flowers are tiny, yellow, in globose pedunculate heads and fragrant with protruding stigmas. The new leaves give a magnificent look, followed by creamy yellow flowers. The tree attracts lots of bees and insects and subsequently birds. The grey or light-black bark is startling yellow when freshly cut but turns pale red-brown on exposure. Hence the name Turmeric wood or Yellow teak. 

Haldu has a striking similarity with Kaim (Mitragyna Parvifolia/कळम) as the flowers and leaves appears almost same. But the leaves of Haldu are nearly circular, heart-shaped at base and with a pointy tip. Also there is difference in the stigma of flowers, if closely admired!

Natural regeneration of this species is difficult as the tiny seeds as well as young seedlings in forests are easily washed away. The proportion of seedlings which survive and establish themselves in forests is relatively very small. Further available trees are cut due to demand for its wood, which is reported to be acid-resistant, making it suitable for use as laboratory bench tops etc. 

Haldu is propagated by seeds. Seed is very small and so should only just be covered with soil. The seed is best sown in a seed-box that is placed in light shade and protected from heavy rain. It should be watered carefully with a very fine spray. Germination ordinarily takes place in about 20 - 40 days. Young seedlings grow very slowly in their first year and are very susceptible to being washed away or beaten down with rain at this time. Plants develop a thin but long tap root in their first year, this thickens and develops considerably in the second year. Growth is faster in the second year and onward.

Young trees prefer a position in light to moderate shade, but become more light demanding as they grow older. It succeeds in most of the soils but well-drained soil, growing best in deep, fairly fertile conditions. For instance, on lower slopes of hills among boulders. Usually growing along rivers or transitional areas between swampy wetlands and dry loamy areas, which are flooded for short periods. The tree has a massive tap-root system in proportion to its size, which makes it very resistant to drought. The tree can tolerate temperatures within the range of 5°- 47°C. 

The Yellow Teak is also harvested for local medicinal use. It pacifies vitiated pitta and known to be useful in inflammation, urinary retention, wounds and ulcers, skin diseases, biliary colic, infection, dysentery, fever and burning sensation.

Haldu is often planted as ornamental, avenue tree and even for its shade. But the tree is potentially great agroforestry species too! The tree produces fuel wood and fodder for livestock. It can be coppiced within limits. It provides good amount of green manure. It yields a yellow dye, which was used for dyeing wool and linen. In some parts of India, the tree has a religious significance in Hindu marriage rituals.

Compost : From Garbage to Garden...

From last post, we have come to know that for solid waste management, there is no throwing ‘away’. The solid waste can be out of our sight, but not out of our environment. Everything we are doing to manage the waste is directly or indirectly affecting us and our ecosystem through pollution.

Composting is a great way of recycling unwanted food scraps & yard waste into a useful garden additive. There is a bit of work involved in composting, but the extra effort well is worth the resulting nutrient rich soil amendment. 

There are many different ways to make compost, with no one method being right or wrong. Many people will try to tell you the ‘proper’ way to compost. But the fact is good compost can be achieved with whatever materials you have available; provided it is biodegradable and free of chemicals, disease or other toxins.

As I previously said, there is no right or wrong way to compost. However, there are good & bad things to compost. Try your own mix of ingredients until you find a recipe that works for you.

The tree leaves that accumulate in and around your landscape represent a valuable natural resource that can be used to provide a good source of organic matter and nutrients for use in your landscape. I have seen many urban dwellers who want to get rid of these fallen leaves. Rather they consider these leaves as nuisance. Either they burn them or send these leaves to dumping yard. Being both of the ways wrong, You must remember that there is no word as ‘waste’ in Mother Nature’s dictionary. Everything that comes from Nature has to go back or it will harm us all. The leaves needs to composted and given back to our soil. It is an established fact that the trees in one acre of forest shed as much as two tons of leaves each year. You may complain that your neighborhood outdoes any forest, but be thankful. Save your leaves. And if your neighbors don’t want them, hang on to theirs. It makes no sense to send valuable treasure to the dump or to burn them!

In forests, sacred groves (देवराई) and pastures, tree leaves and other organic wastes form a natural carpet over the soil surface which conserves moisture, modifies temperatures and prevents soil erosion and crusting. In time, bacteria, fungi and other natural occurring organisms decompose or compost the leaves and other organic material, supplying the existing plants with a natural, slow release form of nutrients. You can, and must, take advantage of this same concept. 

It may be a long process, but I can’t think of any one reason not to make compost for use in your garden. It’s free, simple to do and made from a resource that is never in short supply.

There isn’t anything much easier than making leaf mold. If you have some space in your garden, this is a good way to start composting. While making leaf mold, one can add their kitchen scraps to the pile. This way, he/she can reduce the amount of waste (or a resource!) going to dumping yard.

You want to begin by making sure the leaves are thoroughly moistened. Dry leaves begin to lose nitrogen and this will slow the process of decomposition. There are a few ways to turn leafs into one of the most valuable additives you could put in your soil.

Be sure to mix more brown materials than green materials into your pile to prevent terrible odors. That means you should add more dried stuff such as dried leaves, stalks or straw than the green stuff like fresh yard trimmings, Kitchen vegetable scraps, Weeds, Dead houseplants, Garden debris and cow/horse manure. 

The materials like diseased plants, Meat, bones or fish, glossy paper etc should never be added to a compost pile.

An easy ambitious method is to make a 3 feet by 3 feet cage using stakes & wire. You just have to pile up the leaves in the cage. To ensure even decomposition it is advised to turn the pile occasionally. Always sprinkle water if pile starts to dry. Or you can also rake your leaves into a pile in your yard and leave them there for a year or so. Remember to cover green scraps by dried leaves.

If you have a proper condition for earthworm’s proliferation, then you can get your compost within a really short period of time. Vermi-composting is a way to make high quality compost using earthworms. Worms are food eating machines. Once you have an active worm bin, your kitchen scrapes will quickly become a nutrient rich organic fertilizer.

Some urbanites residing in apartments may excuse that they do not have space required for composting. They can use method which usually consisting of aerated Matkas or drums. There are many NGOs or shops selling these types of compact composting units which can easily fit in your balcony or terrace. One has to have the will, then only there will be a way! Watch this video of Vani Murthy, who composts in her own apartment.

Once the leaf mold is ready, you can use it in many ways. Leaf mold is one of the best soil conditioners, it helps to loosen the soil, making it less dense & easier for roots to penetrate and take up nutrients.

Soil Enrichment - Leaf mulch returns nutrients back to the soil. Your plants and garden will require less or no fertilizer and other additives.

Water Conservation - Leaf mulch helps retain moisture in soils. When soil is covered with leaf mulch, the mulch lowers the soil’s exposure to sun and wind which reduces evaporation.

Save Money - By managing your biodegradable waste on site, you eliminate the costs of pick up & transport and fuel to landfill, making you a more responsible earth inhabitant. 

Insulation - Mulch acts like an insulating barrier from the heat in the summer, from the cold in the winter and from the wind all year round. Mulch prevents compaction and erosion of soils from wind and rain.

Weed Control - Leaf mulch can help prevent the growth of weeds. Add a thick layer (2 to 3 inches) to gardens to reduce the need for herbicides.

With all these great uses why not turn your kitchen and yard waste into a free source of all natural nutrient rich soil additive/fertilizer..?! Composting is a growing solution to solid waste management. Today, knowledge and interest in the science of composting is increasing dramatically. Whether an ancient art or a modern science, composting is a useful and environmentally sound gardening practice for you.

Don't waste the Waste..!

Well… we all have heard, talked or read about the three R's - Reduce, Reuse and Recycling. There is nothing new about them, isn’t it?! But we hardly implement them in our day-to-day life. And that may be because we don’t know or understand the necessity to implement them and about their outcomes. What the R’s are for..?

Nashik is fast growing city. And like any other developing city, our municipal corporation is facing countless challenges due to increase in urban populations such as crowding, transportation, traffic, slums, water supply, power shortages, drainage, and above all, pollution. Pollution is the result of many variables. While air pollution and water quality get maximum share of attention, one pollution source that is largely ignored, though it often stares us in the face is Solid Waste.

Solid waste is defined as non-liquid material that no longer has any value to the person disposing it. Commonly known as garbage, rubbish or trash. Solid Waste Management (SWM) is usually the largest budget item for cities, especially in developing countries. Uncollected solid waste is often the leading contributor to local flooding, air & water pollution and can have an enormous impact on health, local environment as well as on the economy. As cities become larger, consumption of goods and services increases leading to more & more waste. Nashik generates about 450 tons/day of waste. That will be roughly around 165 Metric tons/year. Guess what will be the waste generation of whole world. We need to look at SWM quite seriously now onwards.

This is Garbage Dumping yard of Nashik located near 'Pandavleni'. Everyday, whatever Garbage Vans pick up, is dumped over here. Forget the sight, but it generates terrible smell which one can not stand even for few minutes. To add fuel to the fire, corporation started burning the garbage to create more space for more ‘garbage’, thus making it one of the most polluted area! Basically, Burning or Incineration of waste is not a solution at all! 'Worsening the waste' is what I call it! Burning releases very poisonous & harmful invisible gases Dioxins which are dangerous to human as well as birds & animals. In simple words, burning your waste will result in Landfills in the Sky. With all these, the residential area is not very far from the place. Almost all nearby societies complain about the smoke and smell from the site. The picture speaks for itself. There are people working in this horrible condition for management of this huge amount of garbage, which is increasing day by day. And most of all, the waste management is taking away huge amount of taxpayer's money.

Dumping or Land-filling is the most commonly used method for waste control in developing countries, with many of the dumps in the developing world being open dumps and unsanitary landfills, polluting nearby aquifers, water bodies and human settlements.

How much amount of garbage must be here? Guess... My camera couldn't cover every corner even in it's wide angle. Please see the following image full screen. And just try to compare the height of a human standing in blue outfit near the rising smoke with the height of the garbage mountain...


With no proper planning for waste disposal in place, there is no surprise that our precious but easy resources are over exploited and garbage mountains are being increasingly seen everywhere and the residents are slow-poisoned by the emissions of the burning.

Keeping our cities clean begins with each one of us. When we walk down the streets in our cities we see litter all around us - sometimes garbage bins have more litter around them than inside them. It is so easy to blame the litter and accuse paper, plastics, tin foil and food waste for making our environment dirty and unhealthy. But does paper, plastics, tin, foil and food waste appear magically on our streets and in our neighbourhoods? No, it’s thrown away and disposed of irresponsibly by each one of us!

Waste management in our cities continues to be a problem due to our littering habits and inadequate waste management systems. If we as responsible citizens use and dispose of waste correctly, we can contribute to protecting our environment, conserving natural resources and keeping our cities clean. A waste reduction strategy must be incorporated by each of us whether at home or at work by following the 4R's principle. Yes! Lets add one more R before rest of them.

REFUSE : I think, this is more important principle than the rest 3R. Refuse the single use or disposable products. Items with unnecessary complex packaging can also be refused and to see what can be deleted from our shopping list!

REDUCE : The best way to manage waste is to not produce it. This can be done by shopping carefully and being aware of our choices. Ex. at work, one can cut down on paper use. At home you can begin by purchasing things with lesser packaging, more durable & refillable items, carry your own shopping bag, avoid disposable items and reduce the use of plastics. 

REUSE : It makes economic and environmental sense to reuse products. Sometimes it takes creativity. You can reuse old bottles, jars as storage bins and buy reusable items rather than disposable ones.

RECYCLE : It is a series of steps that takes a used material & processes, re-manufactures and sells it as a new product. Segregate your waste for better disposal and purchase recycled/green products. A ton of paper from recycled material conserves about 7,000 gallons of water, 17-31 trees, 60 lb of air pollutants and 4,000 KWh of electricity. 

The four R's - all help not only to cut down on the amount of waste we throw away, but they also conserve natural resources, landfill space & energy.
Plus, the these R's save the soil or land and money used for landfills.

How?

We can sell unwanted newspapers, glass bottles, old electronic items to the raddiwallas and kabadiwallas (waste traders) - because there is a value in them. There is value too in the waste we dispose of everyday. We can unleash this value only if each household separates its waste into wet and dry. Then may be, we'll all come to know : Waste is actually a resource!

Wet Waste: Food, vegetable peels, egg shells and other organic materials. These are easily biodegradable and can break down and become compost or soil within a short period. Therefore, this waste should go into a compost pit. You can build your own vermi-compost pit in your colony/home and convert all wet waste into useful compost. This would reduce the pressure on our landfills also.

Dry Waste: Paper, plastics, tin, foil, glass, cloth and other materials that do not biodegrade. These materials can be recycled and made into useful products.

Better administration and public infra-structure are an immediate necessity in lower income countries. Most importantly, public attitude needs to be changed as soon as possible. And the change should start from oneself. Unless there is a shift towards a more responsible attitude, no enduring solution is possible. Public education that informs people of options to reduce waste, increase recycling and composting are a good starting point. There is also a need for the design of longer-lasting and reusable products. Municipalities can encourage people to form groups, segregate waste and process it at their end. Repairing, donating, selling and reusing products when possible, especially in the case of e-waste, is also essential. For example, only 5% of India’s electronic waste gets recycled due to absence of proper infrastructure and legislation. And last but not least, each & everyone of us should make an sincere effort to Refuse, Reduce, Reuse And Recycle..!

Today is 5th Anniversary of Gifting Trees. Let us join hands to reduce the load on dumping yard. We all must have a goal of reducing the amount of waste going into landfills by 40 percent. Everyone can help meet this goal and save natural resources, energy and money by following the four R's. Reducing waste also means conserving our limited resources.
