Species distribution modeling is one of many tools available to assist managers in understanding the potential distribution of rare and endemic species when regulating and prioritizing different land-use scenarios. Developing a predictive model of the distribution of a particular species can involve several different techniques, and be reported under a variety of names. In this study we used an iterative modeling approach to investigate the potential distribution of two rare species: Physaria (Lesquerella) congesta (Dudley Bluffs Bladderpod), and Physaria obcordata (Piceance twinpod).
