The U.S. Forest Service has formally commended Rocklin High School senior Rosie Perrot for her efforts in conducting important field research in the Sierra National Forest. Perrot, 17, conducted habitat assessments and species inventories for the Yosemite toad (Bufo canorus). The Yosemite toad is endemic to only the high elevations of the Sierra Nevada mountain range. Researchers believe this species has declined by more than 50 percent over the past three decades and as result the U.S. Fish and Wildlife Service has recognized the Yosemite toad as a candidate species for listing under the Endangered Species Act. The Forest Service commended Perrot because the information she collected while hiking the high country identified several sites occupied by the Yosemite toad. Despite the Yosemite toad’s reclusive lifestyle, Perrot was able to identify several adults in their natural habitat, providing valuable information for further research. The Sierra Nevada mountain range is familiar territory to Perrot. She has been hiking the remote trails with her family each summer since she was 7 years old. Perrot is a published writer as a regular contributor to the Pacific Crest Trail Association's magazine "The Communicator" over the past several years. “Nature has always been my passion,” Perrot explained. “I was thrilled that the Forest Service was interested in having me do research. It felt good to know that I was able to appreciate nature and contribute to helping scientists restore a rare species at the same time.” Perrot is an honor student at Rocklin High School and plans to apply to the University of California system, as well as competitive private universities. She is active in theatre and music at Rocklin High and a member of the Thunder cross country and track teams. She is the daughter of Daniel and Laurie Perrot of Rocklin.
