What is the term for an area that consists of a significant number of trees?

The correct term for an area that consists of a significant number of trees is "forest." A forest is defined by the presence of a large number of trees and a complex ecosystem that includes various plant and animal species. Forests can vary in size and type, ranging from dense tropical rainforests to temperate and boreal forests.

While the term "woodland" might also refer to areas with numerous trees, it typically denotes a less dense growth compared to a forest. "Park" usually refers to the designated land area that may contain various recreational facilities and open spaces, which can also include trees, but does not specifically describe an area dominated by trees. "Forestry" relates to the science and management of forests, including practices like planting and harvesting trees, rather than being a term for the area itself.
