Marci releasing bull troutMarci currently supervises and administers the Recovery Assessment and Planning Program at CRFPO.  Her primary responsibilities include recovery planning and implementation for bull trout, providing technical assistance to other Service offices regarding aquatic trust resources, and managing CRFPO’s social media presence (i.e., Facebook).  Marci started her career with the U.S. Fish and Wildlife Service in 2006 in the Carlsbad Fish and Wildlife Office where she worked as a biologist on Section 7 consultations and Section 10 habitat conservation plans under the Endangered Species Act.  She worked with a variety of listed upland, riparian, and aquatic species including coastal California gnatcatcher, least Bell’s vireo, light-footed clapper rail, thread-leaved brodiaea, tidewater goby, southern California steelhead, arroyo toad, and the Laguna Mountains skipper.  Marci’s research background includes examining the interactive effects of changing environmental conditions (i.e., climate change and eutrophication) on the growth, behavior, and predation risk of kokanee salmon, as well as salmonid bioenergetics and foraging ecology.  Additionally, Marci worked on several projects involving the use of aquatic invertebrates to assess water quality and aquatic ecosystem health.
