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. 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 the NCCN 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 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 geodatabase represents the sampling design used to meet the project's purpose. The sampling design relies upon systematic sampling for smaller parks (LEWI and SAJH) and spatially balanced, GRTS sampling for larger parks (MORA, NOCA, OLYM). The objectives of the landbird monitoring program 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 geodatabase represents the sampling design used to meet the project's objectives. The sampling design relies upon systematic sampling for smaller parks (Lewis and Clark National Historical Park [LEWI] and San Juan Island National Historical park [SAJH]) and spatially balanced, Generalized Random Tesselation Stratified (GRTS) sampling for larger parks (Mount Rainier National Park [MORA], North Cascades National Park [NOCA], Olympic National Park [OLYM]). The GRTS sample design was created using stratified equal probability survey design. Potential transect starting locations were defined based on road and trail networks. The sample design formed the basis for office and field evaluation of selected locations and the subsequent establishment of long-term monitoring transects.

The Southeast Coast Network (SECN) initiated a pilot program using the Variable-radius circular plot point count method as a way to establish a quality-control method for data collected via automated recording devices (ARDs). Landbirds were selected as a vital sign for monitoring due to their interaction with several trophic levels in the environments they reside in, leading to landbird populations being an effective way to analyze the ecological conditions of those environments. The monitoring was performed in the spring of 2009 and 2010, where selected park units were surveyed once. Observations were made from sampling locations scattered throughout each park. Observed birds, either visually or audially, were recorded throughout a 12-minute time period at each sampling point. Over 19,000 observations of 173 species were made across 14 NPS park units in 2009 and 2010. Data collected under this protocol are stored in the SECN data management system and are available online in the Integration of Resource Management Applications (IRMA) database maintained by the Inventory and Monitoring Division national office located in Fort Collins, Colorado.
