Red Alder Growth and Yield Model

The RAP-ORGANON red alder plantation growth and yield model has been updated by the Center for Intensive-planted Silviculture (CIPS) using additional datasets containing older and larger trees. Evaluation of the updated model indicated improvement of density, basal area and stand volume on both control and thinned plots variables relative to the original equations. The updated is currently undergoing rigorous testing and will soon be publically available on the CIPS website.
