The concept of Keystone emerges from the nest-building behaviour of certain birds. These permanent nest structures serve as habitat for many life forms. The nests become essential parts of their ecosystems, a centerpiece which many different species benefit from. Such keystone species become crucial in providing opportunities for other beings to grow and evolve. The Keystone Foundation is born out of this simple ecological principle of the interdependence of natural systems, and strives to provide the opportunity for the growth of all life in the NBR.
