This document compares and contrasts the Guánica State Forest and Caribbean National Forest in Puerto Rico. It discusses how the biodiversity, flora, fauna, and climate differ between the two ecosystems. The Guánica State Forest has higher biodiversity and is more diverse overall due to its location near the coast and exposure to varying temperatures and precipitation, while the Caribbean National Forest has adapted to harsher and more arid conditions inland. The conclusion is that the Guánica State Forest is the more diverse of the two forests compared.
