Global analysis of streamflow response to forest management

Planting large numbers of trees may contribute to improving an ecosystem and mitigating atmospheric CO2 levels. But planting trees in arid areas can sometimes worsen the environmental circumstances, especially the water availability ...

Forest

A forest is an area with a high density of trees. There are many definitions of a forest, based on the various criteria. These plant communities presently cover approximately 9.4% of the Earth's surface (or 30% of total land area) in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. Although a forest is classified primarily by trees a forest ecosystem is defined intrinsically with additional species such as fungi. A woodland, with more open space between trees, is ecologically distinct from a forest.
