A deciduous forest is a biome dominated by deciduous trees which lose their leaves seasonally. The Earth has temperate deciduous forests, and tropical and subtropical deciduous forests, also known as dry forests. Another name for these forests is broad-leaf forests because of the wide, flat leaves on the trees. Trees in tropical deciduous forests lose their leaves in the dry season and regrow them in the rainy season. In temperate deciduous forests, trees lose their leaves in the fall and regrow them in the spring.
