Skunks, opossum, raccoons, coyotes, deer, and elk often are lumped into the unofficial taxonomic family “nuisance wildlife.” Actually, any kind of wildlife can fit this description, from rattlesnakes to woodpeckers, and even beavers. Most often, however, problems caused by nuisance wildlife can be managed or avoided altogether.
Renewable electrical energy sources are relatively easy to integrate at moderate penetrations, utilizing a combination of technical and market methods to increase grid flexibility. However, integrating high renewable portfolios is more challenging, and the optimal combination of resources will vary depending on the features of specific geographic areas. This study...
Fire is an important disturbance mechanism in big sagebrush (Artemisia
tridentata) communities, yet little is known about wildlife population dynamics during
post-fire habitat succession. I estimated the abundance of small mammals and birds in
relation to fire history in mountain big sagebrush (A.t. spp. vaseyana) communities on the
Sheldon National...
Historically fire has been the primary disturbance factor in the sagebrush-steppe. The settlement of the West by Euro-Americans, grazing by domestic livestock, and the concomitant spread of invasive species have altered the historical fire regime. Understanding the long-term vegetation structure and fuel succession of the various sagebrush-dominated communities of this...
• Premise of the study: Seed longevity and persistence in soil seed banks may be especially important for population persistence in ecosystems where opportunities for seedling establishment and disturbance are unpredictable. The fire regime, an important driver of population dynamics in sagebrush steppe ecosystems, has been altered by exotic annual...
The semi-arid sagebrush steppe ecosystem is one of the largest biomes in
North America. The steppe provides critical habitat and forage for wildlife and is
economically important to recreation and livestock industries. However, the ecosystem
is threatened primarily due to several negative effects associated with expansion of the
exotic annual...
1. Seeding native plants is a key management practice to counter land degradation across
the globe, yet the majority of seeding efforts fail, limiting our ability to accelerate ecosystem
recovery.
2. Recruitment requires transitions through several seed and seedling stages, some of which
may have overriding influences on restoration outcomes....

Greater Sage-Grouse (Centrocercus urophasianus) have experienced declines throughout their range over the last 50 years. Long-term declines in sage-grouse abundance in Nevada and Oregon have been attributed to reduced productivity. From 1995-1997, sage-grouse production on Sheldon National Wildlife Refuge (SNWR), Nevada was greater compared to Hart Mountain National Antelope Refuge...
The Lakes Basin Bibliography consists of over 600 references relating to the natural resources of Oregon’s Lakes Basin. Forty percent of the items listed are available to anyone online though not all links are persistent. The remaining sixty percent are held in at least one library either in print or...
