Description
Our study examined fire ecology and addressed ecological effects following wildland fires at high elevations and the fuel mitigation technique of mastication in Colorado and Wyoming, USA. We present in Chapter 1 a brief timeline of wildfire history in North America tailored toward United States Forest Service history. We then present a literature synthesis on anthropogenic changes to fuel structures, and global climate change and bark beetle projections on fire characteristics. We further discuss fuel mitigation techniques available to federal managers as well as their viability, and federal wildland fire expenditures with projections exceeding 3 billion USB by 2037. In Chapter 2 we explore ecological effects following the Beaver Creek and Broadway wildland fires of 2016 at high elevations on the Medicine Bow-Routt National Forests. We employed regression with AICc model selection techniques and multivariate ordination analyses to evaluate top models for three single response variables predicting recovery, and to better understand complex ecological relationships post-fire. In Chapter 3 we evaluated mastication in a ponderosa pine (Pinus ponderosa Lawson & C. Lawson) system as a fuel mitigation technique on the Medicine Bow National Forest. We utilized mixed models to evaluate functional group cover and species metrics in response to mastication treatments. We also created a least squares regression model predicting graminoid cover with woody debris cover.
