Western Red Rot Control for the Black Hills

The ponderosa pine forests of the Black Hills of South Dakota are the only local sources of timber in the midst of a vast treeless area. Losses from western red rot in old growth amount to about 25 percent of the volume cut. Little or no information on the incidence and development of the decay in young timber is available. This paper deals with the problem of controlling future rot losses in young stands, especially those subjected to improvement operations.
