Serpentine Species Monitoring for the Tulare Hill Safe Harbor Agreement

Nomad Ecology conducted eight years of annual monitoring for the 45-acre Tulare Hill property based on a Safe Harbor Agreement developed with the Sacramento Office of the U.S. Fish and Wildlife Service. Species covered, monitored, and subject to this agreement include: bay checkerspot butterfly (Euphydryas editha bayensis), federally Threatened; Santa Clara Valley dudleya (Dudleya abramsii subsp. setchellii), federally Threatened; and Metcalf Canyon jewelflower (Streptanthus glandulosus subsp. albidus), federally Endangered. Nomad collected vegetation data in 25 square meter plots including cover of all plant species, height of all plant species, cover of rocks, litter, and soil, aspect, and slope.

Photographs were taken at all of the plots. This data was used to monitor the quality of habitat for bay checkerspot butterfly. Fenced serpentine rock outcrops were monitored for Santa Clara Valley dudleya. Dudleya plants located within fenced enclosures were counted and photographed. Fenced enclosures and unfenced plots were surveyed for Metcalf Canyon jewelflower. An annual monitoring report was prepared that included setting description, background information, results of the monitoring including an analysis of vegetation, and recommendations. The annual reports were submitted to the U.S. Fish and Wildlife Service.
