Gunnison sage-grouse lek site suitability modeling
In order to better understand and protect species with minimal or decreasing populations, it is imperative to determine their actual existing population size. The focal species for this project is the Gunnison sage-grouse (GUSG), which became a proposed endangered species under the Endangered Species Act, thus confirming the need for better population estimates.

Monitoring intensity and patterns of off-highway vehicle (OHV) use in remote areas of the western USA
The continued growth of off-highway vehicle (OHV) activities – demonstrated by the dramatic increase in OHV sales, number of users, and areas experiencing OHV use – has elevated concerns about their ecological effects, the impacts on wildlife, and the sustainability of OHV use on secondary and tertiary road networks. Conflicts between visitors and wildlife are raising concerns about system resilie

A Regional Approach to Wildlife Monitoring Related to Energy Exploration and Development in Colorado
The U.S. Bureau of Land Management (BLM) is currently developing a National Monitoring Strategy that will guide efforts to create an efficient and effective process for monitoring land health by BLM. To inform the ongoing development of the national strategy, BLM selected two States (Colorado, Alaska) to serve as focal areas on which to base a flexible framework for developing monitoring programs

Environmental effects of off-highway vehicles on Bureau of Land Management lands: A literature synthesis, annotated bibliographies, extensive bibliographies, and internet resources
This report and its associated appendixes compile and synthesize the results of a comprehensive literature and Internet search conducted in May 2006. The literature search was undertaken to uncover information regarding the effects of off-highway vehicle (OHV) use on land health, or “natural resource attributes,” and included databases archiving information from before OHVs came into existence to

Public access management as an adaptive wildlife management tool
Wildlife populations across the United States are benefiting from improved wildlife management techniques. However, these benefits also create new challenges including overpopulation, disease, increased winter kill, and forage degradation. These issues have become the challenges for natural resource managers and landowners. Specifically, elk (Cervus elaphus) populations in the Gunnison River Valle

Roads and traffic: Effects on ecology and wildlife habitat use; applications for cooperative adaptive management
The land of the United States in dissected by more than 4 million miles of roads that fragment wildlife habitat on both public and private lands. Traffic on these roads causes additional effects. On secondary roads, which provide access to the most natural habitat, the levels, timing, and types of traffic are seldom known. In order to understand the effects of traffic on wildlife, USGS is conducti

Evaluating Trends in Greater Sage-Grouse Populations With Quantile Regression
USGS scientists are evaluating the use of quantile regression to develop models of sage-grouse population changes across the United States.
Landscape Genetics of Sage Grouse
Greater and Gunnison sage-grouse populations are species considered for listing under the Endangered Species Act of 1973. Loss and fragmentation of sagebrush habitats are among the primary causes of decline in these species. A fundamental need for species conservation is to identify and subsequently maintain a set of connected populations. Landscape genetics combines the fields of population...
Lek Disturbance Buffer Analysis data, Western Colorado, Derived from Gunnison Sage Grouse Location Data 2010 - 2014
This data release consists of three files (Crawford_and_WGB_Location_Data_S1.csv, Lek_Dist_S2.csv, and Home_Range_Area_S3.csv). The first data set represents specifics about each GPS location representing temporal and spatial relationships used in our analysis including the Month, day and year and local time each location was collected along with distance between locations, elevation in meters, d
