Sites where edaphic endemic plants have evolved exist in isolated, often small patches throughout the Great Basin. Gypsophytes, plants that live on gypsum soil outcrops, are one group of edaphic endemic plants about which information on localities and habitat requirements is needed. An opportunity to provide some protection to gypsophyte species in White River Valley, Nevada, arose with the revision of Ely BLM's Resource Management Plan. Field surveys to gather locality data were performed in 2005 and 2007, and 1840 new localities were identified. Species distribution modeling can be a useful tool for delineating areas for special management to benefit species of concern. Species distribution model inputs included gypsophyte localities, elevation, slope, aspect, and remotely sensed data on probability of gypsum springmound occurrence. Model outputs were refined using field surveys, and four sites with gypsum springmounds with BLM sensitive-status gypsophytes for Area of Critical Environmental Concern (ACEC) status were proposed. These four sites have since been designated, and provide some degree of protection to gypsophytes, though the scattered, isolated nature of gypsum springmounds and other edaphic endemic plant habitats highlights the importance of the use of rare plant locality point data, as well as remotely sensed data and field surveys by land management agency staff in carrying out National Environmental Policy Act (NEPA) planning for projects that have the potential to harm rare plant populations.
