Why Plant Trees?

Trees have always been a key symbol of the environmental movement and there are many like-minded organisations devoting considerable time and energy to planting trees. However, a valid question to pose to any tree planting organisation is why dedicate time and resources to plant trees? Some reasons to justify this are obvious, some not so. Below are some key factors that attempt to show trees are more than a token symbol of environmentalism, they are in fact key components to global ecosystems.

 Carbon sequestration

Trees act as natural filters of our air. Through the process of photosynthesis trees absorb carbon dioxide (a key greenhouse gas and principle contributor to global warming) from the atmosphere and store the carbon in their trunk, branches, leaves, roots, soil and foliage, while releasing oxygen back into the atmosphere. The debate about the use of trees for climate change mitigation has been somewhat heated over recent times, however there is a solid consensus emerging from sound scientific studies that under certain conditions trees do provide a viable means for the net removal of CO2 from the atmosphere.

Trees Produce Oxygen

A fundamental requirement for all animals is a supply of oxygen. Through the process of photosynthesis, trees and other vegetation supply us with this vital gas. One mature tree produces enough oxygen for 10 people to inhale in a year.

Trees improve biodiversity and provide habitat for wildlife

Up to 90% of all terrestrial animals live in association with forest habitats. In simple terms, the less trees the less viable habitat for many species. This will ultimately lead to species extinction, first locally and in many cases globally. Through the restoration of native forest you are providing new or improved habitat for a number of animal species that rely on forests for food and shelter. The animal diversity not only improves in areas that have undergone restoration; plant life equally benefits. Once a framework of tree species is established nature takes over and many additional plant and tree species will regenerate naturally through actions such as seed dispersal facilitated by the increased presence of birds and mammals.

Soil erosion

The removal of trees from the landscape can have disastrous repercussions in terms of making such areas more prone to landslide. Erosion control most frequently involves the planting of tree, shrub or grass species. The roots of the vegetation bind the soil and prevent erosion.

 Water conservation

The instance of flash flooding has been shown to be reduced by the presence of forests. Also in areas prone to drought the addition of trees to the landscape can aid in the conservation of precious water resources. Trees slow down water runoff after periods of heavy rainfalls and help to recharge underground water-holding aquifers.
