Color/Appearance: Nepalese Alder tends to be a light tan to reddish brown; color darkens and reddens with age. There is no visible distinction between heartwood and sapwood. The overall grain pattern and appearance is similar to Birch (Betula genus)—though redder than Birch—and both genera are derived from the same family, Betulaceae.

Grain/Texture: Nepalese Alder has closed pores, and a fine, even, and straight grain.

Rot Resistance: Nepalese Alder is rated non-durable to perishable regarding decay resistance, and freshly cut logs should be quickly converted into lumber and dried to prevent staining or decay in the wood.

Workability: Nepalese Alder is very easy to work with both hand and machine tools; it sands especially easy. The wood is rather soft, however, and care must be taken to avoid denting it in some applications. Nepalese Alder has excellent gluing, staining, and finishing properties; it also turns well and behaves similar to Black Cherry.

Odor: No characteristic odor.

Allergies/Toxicity: Although severe reactions are quite uncommon, Alder in the Alnus genus has been reported to cause eye, skin, and respiratory irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.

Pricing/Availability: No data available.

Sustainability: This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.

Common Uses: Interior utility wood, plywood, boxes, crates, and turned items.

Comments: Nepalese Alder is a very fast growing tree that is native to Southeast Asia, but has been cultivated for plantation growth in a variety of tropical locations, such as Hawaii. The wood tends to be lighter and weaker than the domestic Red Alder found in the United States.
