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.

This dataset represents inputs for a hierarchical Bayesian model of bird population density with respect to fire history in Yosemite National Park (YOSE) and Sequoia and Kings Canyon National Parks (SEKI). The model uses avian point-count data, fire history data and biophysical metrics to assess localized bird population response to years-since-fire and burn severity at thousands of locations across these parks (Ray et al. 2025). Avian point-count time series were generated by The Institute for Bird Populations in collaboration with the Sierra Nevada Inventory and Monitoring Network (SIEN) of the U.S. National Park Service (Siegel & DeSante 2002, Siegel & Wilkerson 2005, Siegel et al. 2010). Fire dates and boundaries were provided by SIEN staff. Biophysical data were accessed from on-line repositories (LANDFIRE and LEMMA GNN). For more information, please refer to Ray et al. 2025.

This data package contains North Coast and Cascades Network (NCCN) Inventory and Monitoring Program landbird monitoring data collected during 2005-2023 at Lewis and Clark National Historical Park (LEWI), Mount Rainier National Park (MORA), North Cascades National Park Complex (NOCA), Olympic National Park (OLYM), and San Juan Island National Historical Park (SAJH). The protocol, publications, and all other associated links can be found in the project reference at: NCCN Landbird Monitoring https://irma.nps.gov/DataStore/Reference/Profile/2097578 National parks in the North Coast and Cascades Network (NCCN) 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 Pacific Northwest 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.

Landbirds are vital to every Northwest ecosystem. They 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 monitoring them is one of the most efficient ways to take the ecological pulse of an area. Surveys were conducted in three large wilderness parks: North Cascades (NOCA), Olympic (OLYM), and Mount Rainier (MORA) National Parks and in two small parks: Lewis and Clark National Historical Park (LEWI) and San Juan Island National Historical Park (SAJH). 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 five NCCN parks during the breeding season and 2) track changes in the breeding season distribution of landbird species throughout accessible areas of the large wilderness parks.

The landbird monitoring protocol established by the Northern Colorado Plateau Network (NCPN) keeps track of landbird populations in its park units to monitor ecosystem/habitat integrity, population declines of certain species of landbirds, and to contribute to regional bird monitoring efforts. Both a point-count and a transect count are done throughout the course of a survey. Observers stop at a designated point-count station for five minutes to record any birds seen within that interval. After the five minute interval, observers walk along the transect to the next point-count station, recording any birds they encounter along the way. The observed bird's species, the approximate distance and heading from the observer to the bird, and environmental conditions during the survey are recorded. This package contains datasets from surveys conducted in 11 park units within the NCPN from 2005-2023, and a separate dataset for monitoring at Pipe Spring National Monument (PISP) from 2009-2019.

This dataset covers three years of parkwide landbird monitoring data collected from 2022-2024 at six national parks and monuments within the Southern Colorado Plateau Inventory Monitoring Network. These data were collected with the objective of monitoring trends in breeding-season density of bird species frequently detected during point count surveys and tracking changes in breeding-season bird community composition at both the parkwide and network-wide scales. Data was collected yearly at Bandelier National Monument, Canyon de Chelly National Monument, Grand Canyon National Park, Mesa Verde National Park, Petrified Forest National Park, and Wupatki National Monument. These parks span an elevational gradient ranging from 1300 to 3000 masl, and encompassing varied habitats including arid grassland-shrubland, riparian woodland, pinyon-juniper woodland, ponderosa pine forest, and mixed-conifer forest. Survey data consists of unlimited-radius, seven-minute passive point-count surveys and includes time removal (interval of detection) and distance sampling (horizontal distance from observer) data. All individuals of all bird species detected by sight or sound were recorded during surveys, which were conducted during a 3.5 hour window immediately following local sunrise. Surveyors additionally classified the habitat at each point count station, and recorded survey-specific environmental covariates including wind speed, environmental noise, cloud cover, and precipitation. Surveys took place from late April through the end of June, with each park or monument surveyed once per year in order of increasing mean elevation. Surveys were conducted off-trail along transects following semicardinal bearings, with transect origin points situated on roads or trails within each protected area. Monitoring transects were randomly placed in a spatially representative manner using the GRTS algorithm.
