Project Summary:
School Spring is located within the Warm Springs complex. The Warm Springs complex contains the only population of the Warm Springs pupfish (Cyprinodon nevadensis pectoralis). The springs within the Warm Springs complex are small in comparison to other springs at Ash Meadows. However, numerous species can be found at the site such as the thermal endemic Warm Springs naucorid (Ambrysus relictus) and Ash Meadows riffle beetle (Stenelmis calida). Numerous threatened and endangered plant species, such as the Ash Meadows Ivesia (Ivesia eremica) and Ash Meadows sunray (Enceliopsis nudicaulis var. corrugata), can also be found within the Warm Springs complex. Modification of springs in the Warm Springs area for culinary and agricultural use began in the late 1800’s to early 1900’s associated with small homesteads.
Two habitat restoration efforts have been completed at School Spring. Beginning in 1969, two earthen ponds were excavated in the vicinity of School Spring and an enclosure fence was installed. One pond was located inside the enclosure and a second pond was located outside of the enclosure for public viewing purposes. The ponds present at School Spring today were constructed in 1983. The habitat construction efforts in 1983 included the construction of concrete and stone lined ponds. The existing concrete ponds are cracked and improved habitat for Warm Springs endemic species is necessary.
The purpose of restoration at School Spring is to create refuge habitat that will promote the recovery of the Warm Springs pupfish and other thermal endemic species that occur within the Warm Springs complex. Restoration at School Spring will serve as an experiment to determine the best approach to habitat construction and restoration at other springs within the Warm Springs complex. In addition, School Spring will serve as a storage facility for native species during restoration efforts at other springs within the Warm Springs complex.
School Spring is isolated from other springs in the Warm Springs complex. Crayfish, a non-native species that competes with and preys upon native species, are present at School Spring. The isolated nature of School Spring may allow the eradication and continued absence of non-native species. Prior to habitat restoration, the water will be diverted from the existing habitat and an attempt will be made to eradicate crayfish from the site by drying out the existing habitat. Habitat construction and restoration will begin following the eradication of crayfish.

Implementation of this project is underway. Stay tuned for updates.
