Valdivian Temperate Rainforest

Located on the western coast of southern South America, it is one of the few temperate rainforests in the world, characterized by oceanic climate influence and high annual rainfall. Unlike tropical rainforests, it features distinct coniferous and broadleaf tree species adapted to cooler temperatures. It spans across regions of both Chile and Argentina.

The forest is the sole habitat of the endangered South Andean deer, locally known as the huemul. It is also home to the monito del monte, a tiny arboreal marsupial, and the world's smallest deer, the pudú. The region's geographical isolation has led to a remarkably high percentage of endemic species.

The ecoregion houses massive ancient trees like the Alerce, some of which are thousands of years old. Because it developed in relative isolation after the last ice age, roughly half of its plant species are found nowhere else on Earth. However, extensive logging and deforestation currently threaten this unique ecosystem.

The climate is heavily influenced by the adjacent Pacific Ocean, resulting in cool, damp, and highly humid conditions year-round. It receives significant annual rainfall, particularly during the winter months. These specific oceanic and climatic conditions are what allow the massive old-growth flora to thrive.
