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.
