Using Prescribed Fire as a Management Strategy in the Turnbull NWR
Year: 2015
Management strategies developed for Turnbull NWR call for the integration of a variety of techniques to restore natural stand conditions, reduce hazard fuels and improve wildlife habitat. These strategies include various types of thinning followed by the application of prescribed fire. On April 14, 2015 the NW Fire Science Consortium sponsored a technical field tour to the refuge led by Mike Rule, refuge wildlife biologist, and Doug Frederick, Assistant Fire Management Officer. The tour included five stops; starting at the Headquarters for an overview of the refuge and discussion on…

Fire Without Borders: Observations, Experiences, and Lessons Learned from the 36-Pit Fire
Year: 2015
The 36-Pit fire near Estacada, OR broke out on September 13, 2014 and spread quickly, burning a total of 5,524 acres. The fire started by a target shooting accident in the 36 Pit quarry. Conditions were very hot and dry when the fire broke out, with temperatures ranging from the upper 80s to the mid-90s, and the relative humidity around 34%. In addition, there were 30 mph winds blowing from the east through the Clackamas River canyon...

A state-and-transition simulation modeling approach for estimating the historical range of variability
Year: 2015
Reference ecological conditions offer important context for land managers as they assess the condition of their landscapes and provide benchmarks for desired future conditions. State-and-transition simulation models (STSMs) are commonly used to estimate reference conditions that can be used to evaluate current ecosystem conditions and to guide land management decisions and activities. The LANDFIRE program created more than 1,000 STSMs and used them to assess departure from a mean reference value for ecosystems in the United States. While the mean provides a useful benchmark, land managers and…

Increasing weight of evidence that thinning and burning treatments help restore understory plant communities in ponderosa pine forests
Year: 2015
For more than a century ecosystems around the world have experienced an increase in the dominance of woody species. While the drivers of woody plant proliferation are complex, interactions between climate and land-use change are commonly invoked as primary contributing factors. In ponderosa pine forests of western North America, substantial increases in tree densities are impacting overall forest health and increasing the risk for severe wildfires and insect and disease outbreaks. Addressing this problem through the use of ecological restoration projects is widely advocated. Our objective was…
