AI overview

Alnus is a genus of trees and shrubs commonly known as alders, which produce distinctive cone-like catkins and are found in forests and wetlands across the Northern Hemisphere and South America. These plants are ecologically important because they form relationships with nitrogen-fixing bacteria that enrich soil, making them valuable for forest ecosystems and land restoration efforts.

Alders are trees of the genus Alnus in the birch family Betulaceae. The genus includes about 35 species of monoecious trees and shrubs, a few reaching a large size, distributed throughout the north temperate zone with a few species extending into Central America, as well as the northern and southern Andes.
