Description: A study at the Institute of Forest Genetics, Placerville. Calif . showed that dwarfmistletoe could spread from infected overstory ponderosa pine into planted Jeffrey pine--a maximum distance of about 145 feet. About one-third of the trees within this distance were infected after 22 years. The level of infection in the trees remained low. however and the parasite had intensified only slightly. Dwarfmistletoe did not appear to have affected height growth. Differences in degree of infection were noticed among blocks of trees from different altitudinal zones.
