Extended Rotation Forest
An extended rotation forest is a forest stand for which the harvest age is increased beyond the optimum economic harvest age to provide larger trees, wildlife habitat In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ..., and other non-timber values. Advantages of extended rotation forestry included enhanced carbon storage, better wood quality and the ability to create habitat for old growth dependent species. The main disadvantages of extended rotations is the lower present value of the stand and timber supply issues. These impacts can be mitigated by the application of commercial thinning. In the Pacific Northwest of the United States, commercially thinned stands have yet to reach cumulation age in spite of reaching ages of over 100 years on good to moderate sites.

Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...
