Dry ponderosa pine/mixed conifer stands in the Southwestern United States create an overabundance of woody biomass during restoration and fuel treatments. It has been the job of land managers and resource specialists to develop management goals and practices to treat stands and lower the risk of catastrophic wildfires while managing for accumulations of woody biomass. Knowing the limitations, setbacks, and successes will help researchers, the United States Forest Service, and other land managers better improve woody biomass utilization. In conjunction with three previous ForBio Southwest studies, we present results from ten phone interviews from three Arizona and New Mexico ranger …

In an era of accelerated climate change, with persistent and increasing disturbance on our landscapes it is important to increase our knowledge of how these natural disturbances effect our lands. This study investigated the changes that take place in ponderosa pine (Pinus ponderosa) stems after death when killed by mountain pine beetle (Dendroctonus ponderosae) and by fire. Trees killed by mountain pine beetle as well as trees killed by fire were sampled and separated into two age classes, those dead 0-4 years and those dead 4+ years. Data was gathered on the modulus of rupture, modulus …
