Tools and Techniques

Models can be used to investigate changes in ecosystems and disturbance regimes across large landscapes and over long periods of time, i.e., at spatial and temporal scales that are typically not possible or practical using field-based observational or experimental methods. These spatially explicit models can also be used to investigate complex relationships and interactions among various...

Accurately quantifying and mapping wildlife habitat is critical to investigations of species distribution and habitat relationships, and can greatly facilitate management of forests for multiple resources. However acquiring field-based, empirical data is often costly and labor intensive. Modeling provides an alternative technique for describing and mapping habitat, but the usefulness of models...

Natural resource managers are faced with the prospect of dramatic climate change, the commencement of ecosystem- and landscape-scale restoration and management initiatives, as well as an interest in learning from and being accountable for restoration projects. The consequent needs for information have motivated many agencies to institute ecological monitoring programs and interdisciplinary...

Genetic and demographic analyses are key to understanding mechanisms of population and species declines and recovery potential. They are equally important to managers assessing risk of extinction relative to the provisions of the Endangered Species Act, and for establishing recovery goals and planning recovery actions. In addition to the methodologically and conceptually complex nature of these...

This research theme informs adaptive management and siting decsions in relation to bats at wind and solar power-generation facilities.

Resource managers contend with achieving goals and mandates in an ever-changing world of exotic species invasions, emerging diseases, extinction risks, and shifting public expectations among others. These challenges must be faced in the context of a changing climate, which potentially alters ecosystem structure and function and undermines the predictability of ecosystem response to management...

Aquatic invasive species, like bullfrogs, stocked fish, crayfish, and reed canarygrass can affect aquatic systems in a variety of ways and have been linked to declines in some amphibians.

This research theme addresses several issues important in deriving accurate and precise estimates of fatality at wind and solar power-generation facilities.

The LTDL was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The project...

Increased wildfire-induced loss of sagebrush in North American shrublands are outpacing natural recovery and leading to substantial habitat loss for sagebrush-obligate species like sage-grouse. The products and information developed for this project will help restoration practitioners, biologists, and land managers evaluate the efficacy of sagebrush restoration approaches as well as their ability...
