BLM REA NWP 2011 Grassland Bird Assemblage Overlapping Moderate and Optimal Maxent Output (WYNDD)

This data set is comprised of a potential distribution model for the Grassland Bird Assemblage within the Northwestern Plains Ecoregion. Observations used in maxent were from 1990 - present and during the months of May - September (birds only). The assemblage includes Baird's sparrow, chestnut-collared longspur, McCown's longspur, Sprague's Pipit and one non bird species, swift fox. Observations for swiftfox related to road kill were removed from the observations.The moderate and optimal maxent model threshold for WYNDD was extracted for each species in the assemblage and overlaid to show where multiple species values overlap. 1 = one species, 5 = all 5 species optimal habitat overlapping.

BLM REA NWP 2011 Fire Return Interval (Majority) by HUC12 for Grassland Bird Assemblage

Grassland habitats are well adapted to periodic wildland fire. Periodic wildland fires maintain high grass vigor, reduce the buildup of thatch, and prevent the encroachment of woody species. Frequency of wildland fire is a major factor influencing the quality of habitat for grassland bird species. Baird’s sparrow reaches peak densities within 2-4 years after a fire, followed by a decline in density. Sprague’s pipits are most abundant in the first 2-3 years post-fire and, in portions of their range, may be absent from native prairie that has not been burned or grazed in more than 8 years. In drier portions of their range, Sprague’s pipits may exhibit high abundance in undisturbed native prairie for longer periods....

BLM REA NWP 2011 Development Layer used for Anthropogenic for Grassland Birds

This development layer was used as part of the Distance to Anthropogenic sources Key Ecological Attribute for the Grassland Birds Assemblage. Its was created by buffering point and line features (roads, oil wells, etc) and merging with raster data such as developed and agricultural lands taken from GAP data sources.
