Endangered Species Recovery Measures
The native crayfish community includes the federally and state-listed endangered Shasta crayfish, Pacifastacus fortis (Faxon, 1914) and the Branchiobdellida or crayfish worm, Magmatodrilus obscurus (Goodnight, 1940). Magmatodrilus obscurus is shown on a rock to the right of center (© B. Moose Peterson, Wildlife Research Photography).
One of the founders of Spring Rivers , Maria Ellis, completed her doctoral research on the interspecific interactions between Shasta crayfish and introduced crayfish species. She wrote the draft Shasta crayfish Recovery Plan for the California Department of Fish and Game and worked with the United States Fish and Wildlife Service to produce the final Recovery Plan for the Shasta Crayfish. Since publication of the Recovery Plan in 1998, Spring Rivers has sought and secured funding to implement high priority recovery measures.
