Utility scale renewable energy development projects are currently proposed across the deserts of the Southwestern United States. Agencies that manage biological resources must understand the potential impacts of these projects and infrastructure (e.g., transmission corridors, substations, access roads, etc.) in order to select appropriate development sites and to mitigate for anticipated effects. Of major concern is determining how future development will impact wildlife movement and genetic exchange among core protected areas and whether increased fragmentation will impact species' abilities to adapt to changing environmental conditions. The adaptive and evolutionary potential of a species is ultimately dependent...

These data are statistical model outputs for Mojave monkeyflower (Mimulus mohavensis ) species distribution, completed by Frank Davis’ Biogeography Lab at UC Santa Barbara. Predictions of habitat occupancy for ~70 species were generated from Maxent models 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-fold cross validated AUC scores. Binary layers depicting predicted suitable habitat were derived using the equal training sensitivity and specificity threshold. Mimulus mohavensis, Max Sensitivity...

These data are statistical model outputs for triple-ribbed milk-vetch (Astragalus tricarinatus) species distribution, completed by CBI. Predictions of habitat occupancy were generated from Maxent models for the DRECP. This species distribution model was produced for a limited extent within the DRECP region, defined as a union of USDA ecoregion subsections with occurrences and 10km buffer of occurrences, at 270 m resolution with 90 detections points obtained March 2013 from CNDDB (California Department of Fish and Wildlife, Biogeographic Data Branch), Consortium of California Herbaria (http://ucjeps.berkeley.edu/consortium/), Â and USFWS Carlsbad Fish & Wildlife Office (http://www.fws.gov/carlsbad/GIS/CFWOGIS.html).The...

DRECP species distribution model output for White-margined beardtongue (Penstemon albomarginatus ).Patrick McIntyre and Kara Moore of UC Davis generated predictions of rare plant habitat occupancy from Maxent models using an approach designed to maximize model ability to identify new occurrences in the field. A three-stage approach was used to build, assess, and finalize distribution models for focal taxa. First, the team built preliminary models at 270 m for each species. Second, field surveys were conducted based on preliminary model predictions. Third, final models were built based on all occurrences, including field data, and assessed for potential biases and model fit. Models were evaluated for their ability...
