The Blacks Mountain Experimental Forest was formally designated in 1934 as the Station's principal site for management studies in the interior ponderosa pine (Pinus ponderosa Dougl. ex Laws. var. ponderosa) type. Studies going back as far as 1910 had resulted in new theories of management, silviculture, and insect control. A primary objective of the Experimental Forest was to develop these theories into a system of management and to test, demonstrate, and improve the system through continuous operation of a timber tract on a commercial scale.
