Thickets of Speckled Alder are used as protective shelter by deer, rabbits, moose and other forest mammals. Moose, beavers, muskrats and rabbits will browse the leaves and twigs of this selection. The seeds and catkins that are produced are eaten by game birds such as grouse and woodcock. The Speckled Alder provides valuable nesting cover for many upland, wetland and songbirds alike. This species is important to beavers as they often use it to construct dams and dens. It's also beneficial when grown along banks of trout streams as it helps keep water temperature lower by providing suitable shade.
