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 HSC was first established in 1988 by a small group of public agencies and industries. 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.
