The term "evergreen forest" refers to forests where the trees retain their leaves throughout the year. This is in contrast to deciduous forests, where the trees shed their leaves seasonally. Evergreen forests are typically found in tropical and subtropical regions, where the climate is warm and humid year-round. Rainforest is a type of evergreen forest that occurs in regions of high rainfall and humidity. Rainforests are home to an incredible diversity of plant and animal life, including many species that are found nowhere else on Earth.
