These data are statistical model outputs for tricolored blackbird (Agelaius tricolor) species distribution, completed by Frank Davis’ Biogeography Lab at UC Santa Barbara. The UCSB Biogeography Lab used Maxent to generate predictions of habitat occupancy for ~70 species for the CA Energy Commission’s project “Cumulative Biological Impacts Framework for Solar Energy in the CA Desert”, 500-10-021. Species distribution models were produced at 270 m resolution using a subset of 22 environmental variables. Models were evaluated with 10-foldcross validated AUC scores. Results are preliminary and have notyet been reviewed by expert biologists. Both continuous probability surfaces and binary layers are available...

This dataset represents current terrestrial intactness values (estimated at the 1km level) within the modeled distribution of the Tricolored blackbird (Agelaius tricolor). Terrestrial intactness is high in areas where development is low, vegetation intactness is high, and fragmentation is low. Consequently, this dataset serves as a general* indication of habitat quality within the distribution of this conservation element. Estimates of current terrestrial intactness were generated by an EEMS fuzzy logic model that integrates multiple measures of landscape development and vegetation intactness, including agriculture development (from LANDFIRE EVT v1.1), urban development (from LANDFIRE EVT v1.1 and NLCD Impervious...

These data are statistical model outputs for Tricolored blackbird (Agelaius tricolor) species distribution, completed by Frank Davis’ Biogeography Lab at UC Santa Barbara. Based on consultation with biologists, CBI used the model's narrow extent output clipped to the following land cover classes: 'Agriculture', 'Grassland', 'Wetland', 'Riparian'. Land cover classes were derived from Dr. Todd Keeler-Wolf’s updated Land Cover/Natural Vegetation Communities dataset generated for the DRECP study area. This vegetation dataset does not extend beyond the DRECP boundary. Consequently, the binary representation of tricolored blackbird habitat is constrained to the DRECP boundary, while the continuous surface extends...
