The distribution of the greater sage-grouse (hereafter sage-grouse; Centrocercus urophasianus) has declined to 56% of its pre-settlement distribution (Schroeder et al. 2004) and abundance of males attending leks has decreased substantially over the past 50 years throughout the species’ range (Garton et al. 2011, Garton et al. 2015, WAFWA 2015). Livestock grazing is a common land use within sage-grouse habitat, and livestock grazing has been implicated by some experts as one of numerous factors contributing to sage-grouse population declines (Beck and Mitchell 2000, Schroeder et al. 2004). However, there are also numerous mechanisms by which livestock grazing might benefit sage-grouse (Beck and Mitchell 2000, Crawford...
U.S Geological Survey (USGS) scientists conducted field data collection efforts during the time periods of September 5 - 14, 2018, November 8 - 13, 2018, June 18 - 27, 2019, July 30 - August 8, 2019, September 13 - 19, 2019, and June 23 - July 1, 2020. These efforts used a combination of technologies to map twenty burned and twelve unburned forest plots at eleven sites in the Black Hills of South Dakota. Twelve burned plots at five sites and nine unburned plots at two sites are located within Custer State Park, five burned plots are located on private land adjacent to Custer State Park at two sites, three unburned plots are located at one site near Hazelrodt Picnic Area in the Black Hills National Forest, and three...
The Hawaii Forest Bird Survey (HFBS) systematically characterized plant and bird communities across transects spanning all major Hawaiian Islands except O‘ahu. This extensive dataset has now been organized into a database and associated geographic information system (GIS) layers. This baseline provides an opportunity to assess how forest ecosystems and their constituent bird and plant populations have changed over time. As part of the HaBiTATS (Hawaiian Biodiversity Trends Across Time and Space) project, a select area on Hawai‘i Island was surveyed in 2015 with the objective of demonstrating the potential of using the HFBS methodology to reassess the status of bird and plant communities across multiple geographic...

Simulated vegetation map for Yosemite National Park in 2069-99 under a future climate from the MIROC general circulation model using the A2 greenhouse gas emissions scenario from the Intergovernmental Panel on Climate Change. This map is fig. 3.5d from Simulating Vegetation Shifts and Carbon Cycling in Yosemite National Park.
This presentation aired as part of the Great Basin LCC webinar series on September 13, 2017. Speakers include Courtney Conway, Idaho Cooperative Fish and Wildlife Research Unit, and Paul Makela, Bureau of Land Management.Description: Greater Sage-grouse have declined since the mid-1960s, and grazing is the most extensive land use within sage-grouse habitat. The speakers will present progress on a 10-year project designed to document the effects of cattle grazing on: 1) demographic traits of Greater Sage-grouse; 2) sage-grouse habitat characteristics, 3) insect abundance, which is important prey for sage-grouse chicks, and 4) abundance of all other bird species. The research team works at five study sites in Idaho...
The Artemisia tridentata spp. wyomingensis (Beetle & A. Young) S.L. Welsh alliance is the most extensive of the big sagebrush complex in the Intermountain West and is characterized by a wide range of environments and vegetation heterogeneity. The purpose of this study was to identify environmental factors driving variation in plant species composition and determine the potential for using environmental factors to explain vegetation characteristics of the A. tridentata spp. wyomingensis alliance. Seventeen environmental factors and seven vegetation response variables were measured on 107 relatively undisturbed, late seral A. tridentata spp. wyomingensis sites across southeastern Oregon and northern Nevada. Non-metric...

FY2016Develop and utilize both correlative and experimental approaches to evaluate effects of different intensities of spring cattle grazing on sage-grouse habitat selection, insect abundance, and sage-grouse demographic and behavioral traits. Collect data and document the effects of different levels of spring cattle grazing intensity on:1) sage-grouse demographic traits; 2) abundance and biomass of arthropods; 3) sage-grouse nest concealment and other vegetation/habitat features.Analyze the relationship between cattle grazing and sage-grouse demography at multiple spatial scales and evaluate the effects of experimental changes in cattle grazing on sage-grouse reproductive parameters.
