Other forms: forests; forested; foresting
A forest is a densely wooded area, or land covered with trees and shrubs. As a verb it means to establish a forest where none existed before.
Famous forests include the Sherwood Forest of Nottinghamshire, England, associated with legend of Robin Hood; the Black Forest of southwestern Germany, so named because it's so dense that very little light enters it; the Amazon Rainforest in Brazil (and 8 other countries of South America); and the forests that make up the Redwood National and State Parks of California, where you can find the tallest trees on earth.
