Thank You Don..

Another Great Data Request.. :thumb:





Many utility scale renewable energy projects are currently proposed across the Mojave and Sonoran Ecoregions. Agencies that manage biological resources throughout this region need to understand the potential impacts of these renewable energy projects and their associated infrastructure (e.g., transmission corridors, substations, access roads, etc.) on species movement, genetic exchange among populations, and species’ abilities to adapt to changing environmental conditions. Understanding these factors will help managers select appropriate project sites and possibly mitigate for anticipated effects of management activities. We are using maximum entropy and resource selection functions with pseudo-absence methods to develop predictive habitat suitability maps for 15 species across the Mojave and Sonoran Ecoregions. We are combining the species suitability maps with genetic diversity data to identif regions containing high genetic diversity and divergence within and among populations and within high suitability habitat that may be important to protect future evolutionary potential. When multiple co-distributed species show spatial overlap in high genetic diversity and divergence, these regions can be considered evolutionary hotspots. See Vandergast et al. 2013 for more details and Mojave results.

Requested Species:
Arizona elegans
Anaxyrus punctatus
Chionactus occipitalis
Coluber flagellum/Masticophis flagellum
Crotaphytus bicinctores
Crotalus cerastes
Dipsosaurus dorsalis
Gopherus agassizii
Lichanura trivirgata
Plestiodon gilberti
Phrynosoma platyrhinos
Sauromalus ater
Sceloporus magister
Uma scoparia
Xantusia vigilis


Intended Use:
NAFHA data will be used to augment species distribution models for multiple species in the Mojave and Sonoran ecoregions.

Scope of data being requested:
All records for species in the list below from the following states: California, Nevada, Utah, and Arizona. See attached map- dashed line.

Potential risks of data being released:
The USGS and its partners are aware of the sensitive nature of the information requested by the project, and will make every effort to keep it secure. Data will not be released publicly, though maps and models of habitat suitability will be made available.
