The forest biome is one of the most important terrestrial ecosystems on our planet. Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions. The temperature varies widely from season to season with cold winters and hot, wet summers. Another feature of temperate rainforests is that they have a dense canopy. Similar to other dense tropical forests, the lack of sunlight on the forest floor means that ferns thrive. Broad-leaved rainforests are found in countries and regions as diverse as New Zealand, Tasmania, Bulgaria, Northwest U.S., Japan, and South America.
