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.
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 ...
Although a forest is usually defined by the presence of trees, under many definitions an area completely lacking trees may still be considered a forest if it grew trees in the past, will grow trees in the future, [20] or was legally designated as a forest regardless of vegetation type.
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 open woodland in North Lanarkshire, Scotland. A woodland (/ ˈ w ʊ d l ə n d / ⓘ) is, in the broad sense, land covered with woody plants (trees and shrubs), [1] [2] or in a narrow sense, synonymous with wood (or in the U.S., the plurale tantum woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American and ...
A pine forest is an example of a temperate coniferous forest Forest communities dominated by huge trees (e.g., giant sequoia, Sequoiadendron gigantea ; redwood, Sequoia sempervirens ), unusual ecological phenomena, occur in western North America, southwestern South America, as well as in the Australasian region in such areas as southeastern ...
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. Forest genetic resources are therefore important to consider in forest management. [16]
[2] [3] Complex early seral forests develop with rich biodiversity because the remaining biomass provides resources to many life forms and because of habitat heterogeneity provided by the disturbances that generated them. [4] [5] In this and other ways, complex early seral forests differ from simplified early successional forests created by ...
