摘要

Ongoing research within the 2002 Hayman burn provides an excellent framework for comparing effects of the Hayman burn to pre-fire forest conditions. Two pre-fire data sets support the proposed research. One characterizes historical landscape structure and key regulating processes and includes plot-level measurements of forest overstory structure, understory species composition, fuels, and fire history. The second dataset is pre-treatment monitoring data collected as part of the Upper South Platte Restoration Project, which includes forest overstory and understory plant data, surface fuels, and habitat monitoring for several species of concern. All of these plots burned with varying intensity. Our primary objectives focus on re-sampling our pre-burn plots near Cheesman Lake and Saloon Gulch to (1) evaluate the effects of burn severity, pre-fire stand characteristics, and topography on tree survivorship; (2) determine the effects of burn severity and pre-fire composition on post-fire understory species composition; (3) examine the effects of pre-fire fuels and vegetation structure on patterns of burn severity, and (4) investigate the effects of burn-severity on habitat for species of concern.
