DescriptionA survey of ponderosa pine needle blight during 1955 and 1956, principally in eastern Oregon (where the disease is much more abundant than in Washington), provided information on extent of damage and on association of infection with certain environmental factors. Observations were largely confined to localities where the disease was known to be more than ordinarily common, and further bias was caused by restriction of the survey to the immediate vicinity of roads. Results, however, were in fairly close agreement with estimates by local foresters and with information from other sources, and are considered indicative of the blight situation in localities where the disease is severe enough to be causing appreciable damage.
