These planning units are characterized by similar bird communities, habitats, and resource management issues. The UMGL JV region is largely covered by BCRs 22 (Eastern Tallgrass Prairie), 23 (Prairie Hardwood Transition), and the U.S. portion of BCR 12 (Boreal Hardwood Transition). Portions of BCR 24 (Central Hardwoods) and 13 (Lower Great Lakes / St. Lawrence Plain) also occur within the JV boundary.</p><p style='background-color:rgb(255, 255, 255); border:0px solid currentcolor; box-sizing:border-box; color:rgb(74, 74, 74); font-family:&quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px; font-style:normal; font-variant-caps:normal; font-variant-ligatures:normal; font-weight:400; letter-spacing:normal; margin:0px 0px 1.5rem; text-align:start; text-decoration-color:initial; text-decoration-style:initial; text-indent:0px; text-transform:none; word-spacing:0px;'>This Model:<br />Targeting conservation to achieve biological objectives for Waterfowl and social objectives for People is a priority for JVs. Blue-winged Teal (BWTE; <i>Spatula discors</i>) is one of UMGL JV's focal waterfowl species. We produced a spatial model (this Polygon dataset) in BCRs 12 and 23 within the JV region to help estimate BWTE population density during the breeding period. We published its map in the JV Waterfowl Habitat Conservation Strategy – 2017 Revision (Appendix A).&nbsp;<br />We started the analyses with BWTE population data from the Waterfowl Breeding Population and Habitat Survey (WBPHS, 2005–2014) conducted in Michigan, Wisconsin, and Minnesota (BCRs 12 and 23). Density estimates from survey segments (400 m wide × 8–48 km long) were calculated, and these estimates were spatially joined to overlapping suitable cover types (potential habitats, extracted from the National Wetland Inventory). Habitat cover types were converted to multiple random points with 100 meter tolerance in-between; these points were then used along with their inherited data from survey segments to conduct kriging interpolation analysis. Portions of BCRs 12 and 23 had no aerial-survey coverage but species distribution was interpolated from neighboring surveyed areas within the BCR. Interpolation was performed while reducing negative effects of spatial auto-correlation, data trends, and directionality. Several models were generated and the best model was selected based on statistical results of cross-validation, such as mean prediction error and standardized root-mean-square of prediction error.&nbsp;<br />This dataset comes with 32 classes of estimated BWTE density and it was summarized in 5 bins for simplicity. For smooth map, it is recommended to visualize using a graduate-color ramp with the 32 classes.
