Location Details/Description: Pixley National Wildlife Refuge, Earlimart, CA


The spatial scope of the project focuses on four resources of concern at Pixley National Wildlife Refuge. These resources are the Remnant Tulare Basin Wetlands, Northern Claypan Vernal Pools, San Joaquin Valley Floor Uplands, and Tulare Basin Riparian Habitat. Deer Creek, which makes up the majority of the riparian habitat for the refuge, has been the main avenue for invasive plant species to establish. Management of riparian areas consist of the chemical treatment of established invasive species and subsequent monitoring for resprouts or new establishments. Whereas management of upland areas primarily consists of cattle grazing to help provide optimum habitat for blunt-nosed leopard lizards (Gambelia silus), Tipton kangaroo rats (Dipodomys nitratoides nitratoides), and San Joaquin kit fox (Vulpes macrotis). Irrigation of the seasonal wetlands occurs to encourage the growth of beneficial foraging vegetation for migratory birds. The remaining acreage of the Refuge is made up of upland habitat, including a wide variety of plant communities such as nonnative annual grass and alkali playas with vernal pools scattered throughout. Most of the upland units of the refuge are adjacent to agricultural fields, where farm workers and equipment can potentially spread invasive species.
