The Hardwood Silviculture Cooperative (HSC) is a multi-faceted research and education program focused primarily on the silviculture of red alder (Alnus rubra) and mixed stands of red alder and Douglas-fir (Pseutotsuga menzeisii).

The Hardwood Silviculture Cooperative (HSC) was first established in 1988 by a small (and visionary) group of public agencies and industries. The HSC has been providing information for foresters interested in hardwood management for over 15 years.

The HSC has the oldest and most extensive red alder growth database in existence. The study design includes thirty-six study installations from Coos Bay, Oregon to Vancouver Island, British Columbia. The goal of the HSC research is simple, to improve the understanding, management, and production of red alder.
