Leguminous trees are a type of tree that belongs to the family Fabaceae, commonly known as the legume, pea, or bean family. These trees are characterized by their ability to fix nitrogen in the soil, thanks to a symbiotic relationship with specific bacteria. This process enriches the soil, making it more fertile and beneficial for other plants. Examples of leguminous trees include Acacia, Albizia, and Mimosa. These trees are often used in reforestation projects and agroforestry systems due to their ecological benefits. Additionally, they provide shade, timber, and food sources for various wildlife and humans alike.
