Forestry
A
forest (also called a
wood,
woodland,
wold,
weald,
holt,
frith, or
firth) is an area with a high density of
trees. There are many definitions of a forest, based on the various criteria. These plant communities cover approximately 9.4% of the
Earths surface (or 30% of total land area), though they once covered much more (about 50% 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
Earths
biosphere. Although a forest is classified primarily by trees a forest
ecosystem is defined intrinsically with additional species such as
fungi.
