This data release provides pinyon jay (Gymnorhinus cyanocephalus) counts and local-scale vegetation data associated with summertime point count surveys conducted throughout the InterMountain West under the Integrated Monitoring in Bird Conservation Regions (IMBCR) program, 2008 - 2020. We also provide code written in the R programming language to model pinyon jay abundance as a function of local-scale covariates.

This data release provides avian data for 11 songbird species (Bewick’s wren [Thryomanes bewickii], black-throated gray warbler [Setophaga nigrescens], Brewer’s sparrow [Spizella breweri], gray flycatcher [Empidonax wrightii], gray vireo [Vireo vicinior], green-tailed towhee [Pipilo chlorurus], juniper titmouse [Baeolophus ridgwayi], loggerhead shrike [Lanius ludovicianus], sagebrush sparrow [Artemisiospiza nevadensis], sage thrasher [Oreoscoptes montanus], and Townsend’s solitaire [Myadestes townsendi]) associated with summertime point count surveys conducted throughout the InterMountain West under the Integrated Monitoring in Bird Conservation Regions (IMBCR) program, 2008 - 2020. Additionally, remotely sensed environmental data used in analyses, summarized at various spatial extents, is included in this data release. Finally, we provide code written in the R programming language to model avian abundance as a function of environmental covariates, evaluate model output for fit and chain convergence, and summarize model results in both table and figure formats.

Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for Californias wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education, and research involving terrestrial vertebrates in California. CWHR contains information on life history, management status, geographic distribution, and habitat relationships for wildlife species known to occur regularly in California. Range maps represent the maximum, current geographic extent of each species within California. They were originally delineated at a scale of 1:5,000,000 by species-level experts and have gradually been revised at a scale of 1:1,000,000. For more information about CWHR, visit the CWHR webpage (https://www.wildlife.ca.gov/Data/CWHR). The webpage provides links to download CWHR data and user documents such as a look up table of available range maps including species code, species name, and range map revision history; a full set of CWHR GIS data; .pdf files of each range map or species life history accounts; and a User Guide.

,This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado. The data table and associated metadata document, which is in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection. The Breeding Bird Survey is a large-scale survey of North American birds. It is a roadside survey, primarily covering the continental United States and southern Canada, although survey routes have recently been initiated in Alaska and northern Mexico. The BBS was started in 1966, and the over 3,500 routes are surveyed in June by experienced birders. Routes 305, Nunn and 901, Rockport are located in the area of the SGS research site. The primary objective of the BBS has been the estimation of population change for songbirds. However, the data have many potential uses, and investigators have used the data to address a variety of research and management objectives. In the USGS-BBS Home Page, reults from the BBS are summarized, and pictures of birds and other species information. Data from 1966 - 2002 were managed by the SGS-LTER project.

This data package contains Sierra Nevada Network (SIEN) Inventory and Monitoring Program landbirds tabular data collected during 2011-2024 at Yosemite National Park (YOSE), Sequoia and Kings Canyon National Park (SEKI), and Devils Postpile National Monument (DEPO). The protocol, publications, and all other associated links can be found in the project reference at: Bird Monitoring Protocol for National Parks in the Sierra Nevada Network: https://irma.nps.gov/DataStore/Reference/Profile/2124954 National parks in SIEN can fulfill vital roles as refuges for bird species dependent on late-successional forest conditions and as reference sites for assessing the effects of land-use and land-cover changes on bird populations throughout the larger Sierra Nevada region. These changes may result from regional processes such as land conversion and forest management, or from broader-scale phenomena such as global climate change. Monitoring population trends at ‘control’ sites in national parks is especially important because the parks are among the few sites in the United States where population trends resulting from large-scale regional or global change patterns are relatively unaffected by local changes in land use. Long-term monitoring of landbirds throughout SIEN provides information that can inform decisions about important management issues in the parks, including visitor impacts, fire management, and the effects of introduced species. Landbirds are critical food-chain links, eating millions of seeds and insects and in turn, are prey for other creatures. Because they have specific needs for food, nest sites, and habitats they are easily impacted by change. For these reasons, birds are among the most sensitive indicators of ecosystem health and counting them is one of the most efficient ways to take the ecological pulse of an area. Surveys were conducted in two large wilderness parks: Yosemite (YOSE) and Sequoia and Kings Canyon (SEKI) National Parks, and in one small park: Devils Postpile National Monument (DEPO). Objectives are to 1) detect trends in the density of as many landbird species (including passerines, near-passerines, and galliformes) as possible throughout accessible areas of three SIEN parks during the breeding season and 2) track changes in the breeding season distribution of landbird species throughout accessible areas of SIEN parks.

These data represents the results of point surveys for birds in west-slope Sierra Nevada forests. There is accompanying habitat data (see Central Sierra Hardwood Study - Habitat) for the survey plots. Please be aware that the coordinates of the points displayed in the text data display of this data set are California Teale-Albers NAD27 projection, but that the data point viewer displays these data points and the background layers in California Teale-Albers NAD83 projection. TIME PERIOD COVERED.The data was collected during the 2003 field season (May-July) by field crews working for California Department of Fish and Game.GEOGRAPHIC EXTENT OF THE RECORDS. Point count locations extend from El Dorado to Tuolumne counties in the central Sierra Nevada between 2000-6000 ft elevation. NUMBER OF RECORDS. There are 64 stands with four landbird point counts per stand. BASE DATA STRUCTURE. The file is a flat excel table which gives the number of landbird species found in each stand. Each stand is represented by two key fields called "Quad" and "Grid" which relate to habitat data from the same plots in another data table. WHAT EACH RECORD REPRESENTS. Each record in the table represents the number of point count locations, average number of individuals, and total number of individuals counted in each stand for each species detected during the counts. There was only one count done at each stand in 2003.
