The term forest-dependent people is used to describe any of a wide variety of livelihoods that are dependent on access to forests, products harvested from forests, or ecosystem services provided by forests, including those of Indigenous peoples dependent on forests. [70]
However, as the term forest connotes an area inhabited by more than one organism, forest ecology most often concentrates on the level of the population, community or ecosystem. Logically, trees are an important component of forest research, but the wide variety of other life forms and abiotic components in most forests means that other elements ...
Old-growth forests tend to have large trees and standing dead trees, multilayered canopies with gaps that result from the deaths of individual trees, and coarse woody debris on the forest floor. [8] The trees of old-growth forests develop distinctive attributes not seen in younger trees, such as more complex structures and deeply fissured bark ...

An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus , live oak , acacias , magnolia , and banksia in more temperate zones, and rainforest trees in tropical zones.
Genetic diversity is needed to maintain the vitality of forests and to provide resilience to pests and diseases. Genetic diversity also ensures that forest trees can survive, adapt and evolve under changing environmental conditions. Furthermore, genetic diversity is the foundation of biological diversity at species and ecosystem levels.
The current oak–hickory forest includes the former range of the oak–chestnut forest region, which encompassed the northeast portion of the current oak–hickory range. When the American chestnut population succumbed to invasive fungal blight in the early 20th century, those forests shifted to an oak and hickory dominated ecosystem.
