Old-growth forests are unique, usually having multiple horizontal layers of vegetation representing a variety of tree species, age classes, and sizes, as well as "pit and mound" soil shape with well-established fungal nets. [20] As old-growth forest is structurally diverse, it provides higher-diversity habitat than forests in other stages.
The trees that form the principal structural and defining component of a forest may be of a great variety of species (as in tropical rainforests and temperate deciduous forests), or relatively few species over large areas (e.g., taiga and arid montane coniferous forests). The biodiversity of forests also encompasses shrubs, herbaceous plants ...
Since the forest is considered an ecosystem, it is dependent on all of the living and non-living factors within itself. This is a major part of why the forest needs to be sustainable before it is harvested. For example, a tree, by way of photosynthesis, converts sunlight to sugars for respiration to keep the tree alive. The remains of the ...
Forest ecology shares characteristics and methodological approaches with other areas of terrestrial plant ecology, however, the presence of trees makes forest ecosystems and their study unique in numerous ways due to the potential for a wide variety of forest structures created by the uniquely large size and height of trees compared with other ...
All people depend upon forests and their biodiversity, some more than others. [6] Forestry is an important economic segment in various industrial countries, [7] as forests provide more than 86 million green jobs and support the livelihoods of many more people. [6]
Dec. 27—Last week, the U.S. Forest Service issued a Notice of Intent to amend the Northwest Forest Plan, which encompasses 19 million acres of federal forest lands in Washington, Oregon, and ...
An example of the biodiversity of fungi in a forest in North Saskatchewan (in this photo, there are also leaf lichens and mosses). Biodiversity is the variability of life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and phylogenetic diversity. [1]
Since the 1970s, forest managers worldwide have considered it best environmental practice to allow dead trees and woody debris to remain in woodlands, recycling nutrients trapped in the wood and providing food and habitat for a wide range of organisms, thereby improving biodiversity.
