What types of trees are planted? Do you plant only indigenous species?
The issue of invasive species is something we deal with very carefully.
We primarily use species that are already naturalized in an area or are native to the area, but, as many of our projects involve working on degraded lands, one of the main criteria is finding trees that will grow quickly and will establish an environment that allows for the native flora to return on its own.
While our goal is the rapid and continued return of indigenous diversity to these lands, the damage to the forests that once stood there makes it impossible to begin with a wide range of indigenous trees and other plants.
Many of the climax species that once inhabited the forest are unable to withstand harsh, direct sunlight. They need the shade that is no longer there. In order to restore the biodiversity, we must plant multi-purpose, fast-growing trees to create conditions that allow the native species to thrive
In this process, we are quite careful to avoid using invasive species, but we do not restrict ourselves to strictly native species. We learned over the years that by initially introducing the proper pioneer tree species, we can bring back the former conditions. Within a very short time, we can bring about the natural regeneration of much of the past diversity that we all desire.
