Historic Range of Variability for Upland Vegetation in the Medicine Bow National Forest, Wyoming

Book Description
An approach for synthesizing the results of ecological research pertinent to land management is the analysis of the historic range of variability (HRV) for key ecosystem variables that are affected by management activities. This report provides an HRV analysis for the upland vegetation of the Medicine Bow National Forest in southeastern Wyoming. The variables include live tree density, dead tree (snag) density, canopy cover, abundance of coarse woody debris, species diversity, fire return intervals, the abundance of various diseases, the proportion of the landscape in different land cover types, and the degree of patchiness in the landscape. The variables were examined at the stand and landscape scales, using information available in the literature and USFS databases. High-elevation landscapes were considered separately from low-elevation landscapes. Much of the report pertains to forests dominated by lodgepole pine, subalpine fir, and Engelmann spruce at high elevations, and by ponderosa pine and aspen at lower elevations. We defined the HRV reference period for the MBNF as approximately 1600 to 1860.

Book Description
This book presents cascading effects of ecological disturbances on a multitude of ecosystem components. It includes agricultural development, large infrequent disturbances, forest harvesting, non-native grazing in deserts, ground transportation, powerline corridors, fires, urban ecology, disturbance in aquatic ecosystems, land-use dynamics on diversity, habitat fragmentation, sedimentation of wetlands, and contemporary climate change. The book facilitates users in understanding why disturbances are occurring while recommending mitigation and remediation strategies.
