Te distribution of prepart type is closely linked to climate zone. Distinct present formations emerge along gradients of temperatur i d precipitation, with each type exhibiting unique structural criteria, species composition, and ecological dynamics. Understanding these accordicosts providees a framework for predisting how forests and timber resources may respond to environmental change.

Tropical Forests

Tropical forests arene found between the Tropic of Cancer and thee Tropic of Capricorn, where temperatures remain consistently warm year-round annual precipitation is abundant.
