What is the natural Habitat of alder plant?

Alder plants primarily thrive in wetland areas, such as riverbanks, floodplains, and marshes. They prefer moist, well-drained soils and are often found in regions with abundant water sources. Alders can also tolerate a range of soil types, including sandy and clay soils, and are commonly found in temperate zones of North America, Europe, and Asia. Their ability to fix nitrogen makes them beneficial for improving soil fertility in their natural habitats.
