RestoreNet is partnering with the Gornish lab at the University of Arizona to better understand how a plant’s source location (provenance) influences its performance in a restoration setting. This greenhouse experiment will be conducted by PhD student, Sierra Lauman.

Early Life Stage (ELS) tests are used as an alternative to traditional whole-animal testing methods for evaluating toxicity of chemicals. ELS for birds involve injection into the air cell of fertile eggs early in development and artificial incubation for several days at which point tissues are sampled for analysis.

Once thought to be extinct, the Pacific pocket mouse (Perognathus longimembris pacificus) was rediscovered in 1993 and is currently found at three population sites along the southern California coast.

The United States is developing renewable energy resources, especially solar, at a rapid rate.

The light-footed Ridgway’s rail, a handsome but secretive waterbird that lives on tidal marshland fragments in southern California from Santa Barbara County south to Baja California, Mexico.

USGS is gathering and analyzing DNA from blood samples throughout the subspecies’ range to document the light-footed Ridgway’s rail’s genetic health.
