Identifying The Effects Of Land Use And Policy On Disturbance Regimes In The Teanaway Community Forest, Washington, Savannah Bommarito
Identifying The Effects Of Land Use And Policy On Disturbance Regimes In The Teanaway Community Forest, Washington, Savannah Bommarito
All Master's Theses
The historic fire regime of the forests of the Eastern Cascades, Washington, has been described as one of high-frequency, low-severity fires using fire scar analysis. Over the past few centuries, the historically open, park-like ponderosa pine-dominated stands have been significantly altered due to Euro-American land use change such as fire exclusion, grazing, mining, and logging. The eventual encroachment of shade-tolerant species has resulted in a high-density forest structure that promotes rare, but extreme fire behavior and heightened susceptibility to insect attacks. As a result, the current disturbance regime is significantly less frequent and of higher severity, posing risks to forest …
Holocene Fire History Reconstruction Of A Mid-Evaluation Mixed-Conifer Forest In The Eastern Cascades, Washington, Zoe Rushton
Holocene Fire History Reconstruction Of A Mid-Evaluation Mixed-Conifer Forest In The Eastern Cascades, Washington, Zoe Rushton
All Master's Theses
Fire histories of mid-elevation mixed-conifer forests (MEMC) are uncommon, particularly in the eastern Cascades of Washington. As a result, fire regimes and the effects of 20th century fire suppression in these forests are not well understood. In the summer of 2014 a 7.80 meter-long sediment core was extracted from Long Lake, located approximately 45 km west of Yakima, WA, which exists in a grand fir-dominated mixed-conifer forest. Fire activity for the Long Lake watershed was reconstructed using macroscopic charcoal analysis and pollen analysis was used to reconstruct vegetation change through time. Charcoal results show low fire activity in the early …

Incorporating User Data In Cross Boundary Trail Mangement: A Case Study Of The Foothills Trail Systemnear Wenatchee, Wa, Beth Macinko
All Master's Theses
Land managers for areas where recreation occurs balance minimizing impacts on the landscape with providing recreation opportunities. Use characteristics including type of use, use frequency, and use patterns have been shown to influence the severity of landscape impacts from recreation. Collecting and incorporating user data is critical to effective recreation management. The Foothills trail system is a nonmotorized, day use trail system adjacent to the city of Wenatchee, Washington that crosses public and private properties. This thesis obtained data on user demographics, use characteristics, user perceptions, and spatial use patterns through a questionnaire administered through a mixed method sampling approach …
