Abstract

Mixed-conifer forests occupy about 6,000 square miles of southwestern Oregon. These forests are characterized by a mixture of Douglas-fir, sugar pine, ponderosa pine, and other species, with Douglas-fir the most abundant. This paper reports the results of a study comparing the site index of Douglas-fir, sugar pine, and ponderosa pine in the South Umpqua drainage above Elk Creek and gives preliminary recommendations concerning choice of species to grow.
