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 (Pseudotsuga menziesii).

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 20 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.


At A Glance

Red alder Growth and Yield Model! - After many years of development, the first-of-its-kind red alder plantation growth and yield model has been developed using the ORGANON architecture. In addition, a new user-friendly interface for this model has been created by the Center for Intensive-planted Silviculture (CIPS). Click here for the link to download the model and here for the link to download the model interface.
