Abstract:

As a result of repeated forest regeneration failures on poor sites in southwest Oregon and northern California, some clearcuts have remained without conifers for several years. A greenhouse bioassay with Douglas-fir (Pseudotsuga menziesii) and ponderosa pine (Pinus ponderosa) as hosts, was conducted to compare abundance of ectomycorrhizal fungus propagules in soils from 36 such clearcuts and adjacent undisturbed forests. Mycorrhizal colonization after 14-16 weeks was high (80-100 percent of root tips mycorrhizal) for seedlings grown in soils from undisturbed forests. Approximately 20 percent fewer mycorrhizae formed on seedlings grown in soils from clearcuts which had not been burned; there was a 40 percent reduction in mycorrhizal colonization of seedlings grown in clearcuts which had been burned. Forest Sci. 30:300-304.
