Description: Many stands in southeast Alaska harvested since 1950, especially where there has been a high degree of disturbance of mineral soil, have regenerated to red alder (Alnus rubra Bong.) and are now approaching maturity. The availability of red alder raises questions addressed in this study about the recovery of lumber from this resource. Information in this study was obtained from trees estimated to be 46 years old on a site outside of Ketchikan. Rates of recovery using a thin-kerf portable band mill were higher than those reported by larger production mills in Washington and Oregon. Grade yields of the Alaska material are comparable to those attained in other regions. This study determined that there were no significant differences in material characteristics that would set this Alaska log resource apart from red alder in the other regions of North America. The potential value of the products is sufficient to allow production in Alaska for use in the manufacturing of value-added products within the state or shipment of finished lumber to domestic or export markets.
