Title: Effects of Prescribed Burning on Mycorrihizal Fungi in Crater Lake National Park

Project Proposal Abstract: Mycorrhizal fungi are essential for survival and growth of all woody terrestrial plants in western North America. The fruit-bodies of these fungi are also important food resources for most forest mammals. Over 90% of the diet of the northern flying squirrel, a major prey species of the northern spotted owl and hence an important component of the owl's habitat, consists of fruiting bodies of truffle and truffle-like species of mycorrhizal fungi. Many mycorrhizal fungi produce edible mushrooms of recreational and commercial value, such as chanterelles, matsutakes, and morels. Effects of prescribed fire on populations and fruit-bodies of mycorrhizal fungi are little studied but constitute an important ecological aspect of burning. The study proposed here will utilize the replicated prescribed burn study by Dr. James Agee and Dr. Mark Huff funded by JFSP, and established in 2002 in Crater Lake National Park. Treatments are early and late spring and fall burns plus nonburned controls. Fungus plots will be placed within each burn treatment replicate for collection of data in spring and fall over 3 years, beginning in 2003, as follows: number of species of mycorrhizal fungi, number and biomass of fruit-bodies by species, and area occupied by mycorrizal mycelial mats in the soil. Both epigeous (mushroom forming) and hypogeous (truffle forming) species will be collected. Data on explanatory variables collected by Dr. Agee and us will be shared to expand the statistical analyses and interpretive value of both studies. The results will be interpreted in terms of effects of the treatments on fungal fruiting populations with special reference to providing managers with information for scheduling prescribed fire to minimize damage to mycorrhizal fungi and their ecosystem functions.
