Evergreen species in tropical forests are usually hardwood species with normally large leaves, but in boreal forests, evergreen species are usually softwoods with needle-leaves.

The ability of an individual tree to reach the overstorey depends on its relationship with neighboring trees and plants; specifically, how fast the tree grows and occupies the growing space and how it tolerates being affected by the surrounding plants on the site. Once a tree with a long life-span occupies the overstorey, it exerts great influence on the understorey of the community by affecting the growing conditions in the understorey. Dominant trees affect the illumination, temperature and m o i s t u r e conditions, and modify the e n v i r o n m e n t t h r o u g h o t h e r mechanisms such as allelopathy.
