Taxonomic uncertainty can be assessed using genetic data, along with other lines of evidence (such as morphological and behavioral characteristics). Such data can be used to identify and assess taxonomic boundaries (species, subspecies, hybrids) and in many cases redefine them. Such delineations are highly relevant for species status determinations (endangered, threatened, or at-risk).

Family relationships and mating systems can be investigated and defined using genetic data. This information is potentially important for conservation and management as it may influence effective population size and levels of genetic diversity.

Population models can incorporate genetic data to assess potential impacts of different management strategies on connectivity, effective population size, and genetic diversity.

The ultimate success of North American Waterfowl Management Plan (NAWMP) depends on maintaining relevance to stakeholders and society. In order to be relevant, a first step is to better understand what people value in regard to waterfowl and their habitats.

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...

USGS and university researchers analyzed changes in male sage-grouse lek counts in Wyoming from 1984 through 2008, measuring disturbance owing to oil and gas development.

USGS scientists and partners investigated sage-grouse population trends in Wyoming and at multiple spatial scales.

US Geological Survey scientists and collaborators are using genetic information contained in sage-grouse feathers collected at leks to define the rangewide network of breeding populations.

USGS has developed Greater Sage-grouse habitat-selection models for the nesting, summer, late brood rearing, and winter life stages in Wyoming to assess habitat quality and responses change across large landscapes.
