Description
This data package includes data that were collected from 2007-2018 as part of the Southern Colorado Plateau Network's habitat-based bird community monitoring protocol. Data were collected at eight ecological sites, representing homogenous habitat and soil types, at six national park service units (BAND, CACH, GRCA, MEVE, PEFO, WUPA). Data was collected in four overall habitat types: grassland-shrubland, riparian woodland, pinyon-juniper woodland, and mixed-conifer forest. The data set contains habitat-specific repeat visit bird survey data collected every three years at each park using point counts with distance sampling. Covariates influencing species detectability were collected during each survey, including percentage cloud cover, wind speed, precipitation, environmental noise, and survey time and date. In addition, microhabitat data was collected in each survey year at each point count station, including plotless measures of tree basal area by species and snag basal area, percentage canopy cover, sapling density, and categorical measures of foliage cover and foliage height in six different vegetation strata (herbaceous, dwarf shrub, shrub, sub-canopy, canopy, and emergent).
