Effect of firewood harvesting on birds in a California oak-pine woodland

Publications Posted on: August 01, 2018
Despite a history of oak clearing and thinning in California, little is known about the effects of firewood harvesting on wildlife in oak woodlands. We studied the effect of firewood harvesting on population trends of birds during the breeding season in an oak-pine woodland in the foothills of the northern Sierra Nevada, California.

Foraging ecology of Nuttall's Woodpecker

Publications Posted on: August 01, 2018
I studied relative abundances, foraging behavior, and foraging habitats of Nuttall's Woodpeckers (Picoides nuttallii# at three California locations. Population sizes at two areas in the foothills of the Sierra Nevada were larger than the population in the Tehachapi Mountains. These differences were attributed to habitat and weather differences.

Evaluating changes in drought resistance across California ecosystems

Science Spotlights Posted on: December 22, 2016
Using satellite imagery, this study identifies California ecosystems that are most resistant to drought. Changes in water use efficiency were used to measure ecosystem drought resistance, to improve our understanding of how ecosystems respond to water limitation.

Forest Service science bolsters sagebrush and sage-grouse conservation

Media Gallery Posted on: September 16, 2016
Sagebrush ecosystems are among the largest and most threatened ecosystems in North America. Greater sage-grouse has served as the bellwether for species conservation in these ecosystems and has been considered for listing under the Endangered Species Act several times. The 2016 Conservation and restoration of sagebrush ecosystems and sage-grouse: An assessment of USDA Forest Service Science assessment will help meet continuing widespread concerns and calls for science-based conservation to mitigate threats to sagebrush ecosystems, conserve populations of sage-grouse and other sagebrush-obligate species, and restore sagebrush ecosystems throughout the western United States. 

Forest Service science bolsters sagebrush and sage-grouse conservation

Science Spotlights Posted on: August 19, 2016
USDA Forest Service (FS) has been a leader for several decades in developing science and applications to support conservation and restoration of sagebrush ecosystems and sage-grouse populations. This spotlight describes an assessment that explains how and why understanding and supporting FS science is crucial for future management of sagebrush ecosystems.

The effectiveness and limitations of fuel modeling using the fire and fuels extension to the Forest Vegetation Simulator

Publications Posted on: June 09, 2015
Fuel treatment effectiveness is often evaluated with fire behavior modeling systems that use fuel models to generate fire behavior outputs. How surface fuels are assigned, either using one of the 53 stylized fuel models or developing custom fuel models, can affect predicted fire behavior. We collected surface and canopy fuels data before and 1, 2, 5, and 8 years after prescribed fire treatments across 10 national forests in California.

Use patterns and visitor characteristics, attitudes, and preferences in nine wilderness and other roadless areas

Publications Posted on: March 23, 2015
Presents a summary and analysis of data from a survey of visitors to eight wildernesses and related areas in the Montana and Idaho Rockies and to one wilderness in the California Sierra Nevadas.

Reducing post-fire runoff and sediment yields

Documents and Media Posted on: January 23, 2015
Agricultural straw, hydromulch (a matrix of organic fibers mixed with water that binds to soil), and wood shred or wood strand mulches increasingly are being used as postfire hillslope treatments. However, the differences in effectiveness in reducing measured runoff, sediment yields, and peak flow rates among these mulch treatments are not fully understood.
