To determine the number of cavity-containing aspens in old-growth (>80 years), we counted the number of stems containing cavities in 132 0.02-ha plots in Wyoming. There were 8.7 cavities/ha of aspen type. At least 84% of the cavity stems were alive when the initial cavity was constructed; 60% were alive when examined. Fruiting bodies and Phellinus tremulae (a heartrot fungus) were present on 71% of all cavity-bearing stems but on only 9.6% of all stems >15 cm d.b.h. Cavities were present in 7.7% and 0.2% of living stems with and without fruiting bodies, respectively. Average d.b.h. of cavity stems …

Recognizing the historical abundance of major vegetation cover types is the foundation for estimating the magnitude and significance of conversion from one cover type to another and the proportion of existing cover types that are in properly functioning condition. Techniques to determine desired conditions are discussed. Existing situations for the need to treat ecosystems where aspen (Populus tremuloides Michx.) occur are prioritized: highest—mixed-conifer with aspen but where conifers comprise greater than 50% of the canopy; high—aspen/sagebrush transition; and moderate—aspen dominated landscapes. Though aspen stands are evaluated, aspen landscapes are discussed in the context of aggregations of many stands. Within …
