obtain particularly desirable items. Breeding occurs once per annum during the autumn. Adults attain sexual maturity by the end of their second summer. A female can be expected to generate approximately 50 to 120 eggs per breeding season, which remain attached to the mother for the entire winter. Studies on other family members suggest a lifespan for this species of several years. Conservation Syncaris pacifica and associated native aquatic species Protect and manage S. pacifica populations and habitat once the threats are removed and restoration has been completed Monitor and evaluate S. pacifica habitat conditions and populations Assess effectiveness of various conservation efforts Conduct research on the biology of the species Restore and maintain viable S. pacifica populations at extirpated locations Increase public awareness and involvement in the protection of S. pacifica and native cohabiting species Assess effects of various conservation efforts on cohabiting native species Assemble a S. pacifica recovery team There are individual efforts occurring in various stream segments, one of the most notable being Students and Teachers Restoring A Watershed (STRAW), a grassroots conservation program to restore over of Stemple Creek by students at Brookside School in Marin County. In this case students raised money, lobbied legislators and succeeded in obtaining grant funds to prevent cattle grazing within the creek, one of the greatest habitat threats. Although a new location of Syncaris pacifica was found in the 1990s at Olema Creek, the general trend for the population of this organism is decline. For example, 1999 surveys in Marin County found fewer individuals present than a comparable 1997 survey.
