ECOLOGY OF ECTOMYCORRHIZAE IN NORTHERN ROCKY MOUNTAIN FORESTS A1 an E. Harvey, Research Plant Pathologist USDA Forest Service, Intermountain Forest and Range Experiment Station Mi chael J. Larsen , Research Mycologist Center for Forest Mycology Research USDA Forest Service, Forest Products Laboratory Martin F. Jurgensen, Professor of Forest Soils Department of Forestry Mi chi gan Technological University ABSTRACT Activity of ectomycorrhizal symbionts depends on the nature of the soil and vegetation, as controlled by climate and natural or man- caused disturbances over time. Organic materials in the form of litter, humus, decayed wood or charcoal that occur in layers or mixed in the mineral soil are key factors governing ectomycorrhizal activities in forest soil s. Importance of these organic fractions to ectomycorrhizal activity can be predicted, based on their quantity and distribution in the forest floor, the season, and the relative position of the site along a temperature-moisture gradient. Organic materials are most important in the harshest soils. This appears to result directly from their ability to buffer wide variations of pH, moisture and temperature. Because the ectomycorrhi zal association depends on host trees, manipulations of the stand also provides direct control of ectomycorrhizal activity. KEYWORDS : harvesting, residues, fire, biological impact, soil qual i ty, ectomycorrhizae. INTRODUCTION The strong positive effect of soil organic layers or organic amendments on abundance of ectomycorrhizae (Mikola 1973; G6bl 1967; Rayner 1936) and the dependence of conifers on this symbiotic association (Trappe and Fogel 1977) suggests a relationship between organic materials and soil qual i ty. The ability of decayed wood to support ectomycorrhizae (Harvey and others 1976; Zak 1971 ;
