Additionally, alder wood is valued for its durability and is used in carpentry, furniture-making, and as fuel.
In summary, Genus Alnus is a taxonomic classification referring to a group of trees and shrubs known as alders. They are characterized by their deciduous nature, distinctive leaves and catkin flowers, and their ability to enrich soil through nitrogen-fixation. Alders are ecologically important and have practical applications in various industries.
