Investigating Calving Areas for Rocky Mountain Elk on the Plumas National Forest: Implications for Land Management

Creator:: Marshall, Abigail C.
Abstract:: Sustainable elk (Cervus canadensis) habitat management on U.S. Forest Service (USFS) lands involves a complex relationship between management practices and ecological processes. A relatively novel Rocky Mountain elk population (Cervus canadensis nelsoni) on the Plumas National Forest (PNF) in northeastern California became established in the early 2000s, but there is...

Evaluation of the effects of silvicultural and fuels treatments on potential fire behaviour in Sierra Nevada mixed-conifer forests

Creator:: Stephens, Scott Lewis
Abstract:: Fire suppression has increased fuel loads and fuel continuity in mixed-conifer ecosystems, resulting in forest structures that are vulnerable to catastrophic fire. This paper models fire behaviour in a mixed-conifer forest and investigates how silvicultural and fuels treatments affect potential fire behaviour. The computer program FARSITE was used to spatially...

Southern Sierra Nevada Fractional Land Cover 2014 - 2018

Creator:: McGregor, Eric L., Green, Rebecca E., Purcell, Kathryn L., Tucker, Jody M., Matthews, Sean M., and Green, David S.
Abstract:: This dataset is designed to capture landscape changes brought on by a severe tree mortality episode in California's southern Sierra Nevada range, by mapping multiple land cover types in a continuous way at annual time-steps throughout the mortality event. By mapping multiple land cover types we can see not only...

Nest trees of northern flying squirrels in the Sierra Nevada

Creator:: Meyer, Marc D., Kelt, Douglas A., and North, Malcolm P.
Abstract:: We examined the nest-tree preferences of northern flying squirrels (Glaucomys sabrinus) in an old-growth, mixed-conifer and red fir (Abies magnifica) forest of the southern Sierra Nevada of California. We tracked 27 individuals to 122 nest trees during 3 summers. Flying squirrels selected nest trees that were larger in diameter and...

Forest pattern, fire, and climatic change in the Sierra Nevada

Creator:: Miller, Carol and Urban, Dean L.
Abstract:: In the Sierra Nevada, distributions of forest tree species are largely controlled by the soil-moisture balance. Changes in temperature or precipitation as a result of increased greenhouse gas concentrations could lead to changes in species distributions. In addition, climatic change could increase the frequency and severity of wildfires. We used...

A study of soil disturbance and compaction resulting from the use of ground-based logging vehicles in the Sierra Nevada

Creator:: Lysne, David Holtan
Abstract:: Some results of a study conducted in the Sierra Nevada Mountains west of Lake Tahoe are reported. The study measured soil impacts resulting from the use of a Caterpillar Tractor model D6D, a John Deere wheeled skidder model JD-640, and an FMC Corporation model FMC 21OCA logging vehicle. The three...

Reconnecting aquatic habitats : validating historical habitat use by anadromous fishes using telemetry and stable isotope analysis above barriers

Creator:: Lewis, Sierra Koch
Abstract:: I conducted a study to identify potential spawning habitat for anadromous salmonids above a 60-year-old hydropower dam in the headwaters of the North Umpqua River in Oregon. Like many other historical salmonid-bearing rivers, little documentation exists for anadromous fish presence above potential natural obstacles upstream of Soda Springs Dam. My...

Soil arthropod responses to different patch types in a mixed-conifer forest of the Sierra Nevada

Creator:: Marra, James L. and Edmonds, Robert L.
Abstract:: The Teakettle Ecosystem Experiment in the southern Sierra Nevada is using thinning and prescribed fire to recreate historical stand conditions. As part of Teakettle we assessed pretreatment diversity and density of the soil arthropod community in 1998 and 2000. We determined the density and diversity of soil microarthropods among treatment...

Skyline logging production in the southern Sierra Nevada mountains: a case study

Creator:: Mann, John William
Abstract:: This paper describes the results of a time study conducted on the Sierra National Forest to determine production capacity of the Madill 044 Skyline Yarding Crane operating in a partial cut situation for old-growth mixed conifer stands. The yarder was rigged in the running skyline configuration and used a Danebo...
