Alnus (Alder)
Alders is highly adaptable to wet or poorly drained soils, making them a valuable asset in wetland restoration projects and waterlogged areas. Its nitrogen-fixing ability enriches the soil and supports the growth of other plants. Alder plays a crucial role in restoration projects, where their rapid growth and ability to thrive in wet soils help stabilize streambanks and improve water quality. Planting Alders along watercourses can enhance biodiversity and restore degraded habitats.
