Process Step:
Process Description: The distribution of the Mojave desert tortoise is represented based on the results of a USGS maximum entropy model of tortoise (Nussear et al. 2009). We used a threshold value of 0.7 to convert the continuous surface of habitat suitability values generated by this model into a binary representation of habitat/non-habitat, and clipped the model extent at the Colorado River to only capture the Mojave population. The original data is mapped at 1-km resolution but was resampled to 30 meters for consistency with other data sets.
