A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle
Master's Projects and Capstones
Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an extent …

Opportunities And Constraints Of Sierra Nevada Meadow Restoration For The Mountain Yellow-Legged Frog Species Complex, Allie E. Sennett
Master's Projects and Capstones
Amphibian populations worldwide are experiencing precipitous declines as a result of disease, introduced species, habitat loss, and climate change. The mountain yellow-legged frog (MYLF), once considered the most abundant vertebrate in the Sierra Nevada, has suffered dramatic population declines in recent decades, and implications of their decline include biodiversity impacts throughout this region. Specifically, the distribution of MYLF has severely contracted within their geographic range, with an obvious shift in overall abundance to sites toward the upper reaches of their elevation range. MYLF occupying high-elevation habitats (i.e., lakes and ponds) must overwinter for especially prolonged periods, which decreases their ability …
