A deciduous forest is a type of forest characterized by trees that lose their leaves each autumn. These forests are typically found in temperate regions, where there are four distinct seasons: spring, summer, autumn, and winter. Common trees in deciduous forests include oak, maple, and birch. The changing seasons create a dynamic environment, with vibrant foliage in the spring and summer, colorful leaves in the fall, and bare branches in winter. Deciduous forests support a variety of wildlife, including deer, foxes, and numerous bird species, making them rich ecosystems that play a vital role in the planet's biodiversity.
