Grey Alder

Grey alder (Alnus glutinosa pictured)

Common Name(s): Grey alder, speckled alder

Scientific Name: Alnus incana

Distribution: Native to Central Europe; various subspecies are also found in temperate regions of North America and Asia

Average Dried Weight: 29.2 lbs/ft3 (465 kg/m3)

Janka Hardness: 770 lbf (3,410 N)*

*Estimated hardness based on specific gravity

Comments: Grey alder is closely related to Alnus glutinosa, another alder species native to Europe. However, grey alder tends to occur as smaller, more multi-stemmed trees that are less suited to commercial harvesting for lumber. However, if clear, defect-free pieces can be obtained, the wood from the two species are very comparable.

Hello, I live in Canada (B.C.). We have two types of alder growing here. I would recommend, adding some of the ecological benefits that alders add to ecosystems.
