Forest

A forest, also referred to as a wood or the woods, is an area with a high density of trees. As with cities, depending on various cultural definitions, what is considered a forest may vary significantly in size and have different classifications according to how and of what the forest is composed. These plant communities cover approximately 9.4 percent of the Earth's surface (or 30 percent of total land area), though they once covered much more about 50 percent of total land area
