Biological Resource Inventories & Mapping

Project Name: Butler Ranch Subdivision Project, Ventura County, California Services: Biological Resource Inventories and Mapping Client: Robert Butler

Padre prepared an extensive biological inventory for a 600 acre property located between Moorpark and Simi Valley, in Ventura County, California. In addition, an Initial Study Biological Assessment was prepared according to the Ventura County ISBA Guidelines. Special-status species observed at Butler Ranch included Catalina mariposa lily, narrow-leaved stillingia, coastal western whiptail, white-tailed kite, Costa’s hummingbird, Nuttall’s woodpecker, oak titmouse, Southern California rufous-crowned sparrow, and lark sparrow. Padre biologists worked closely with the project engineer to develop a tract map that would minimize habitat loss for special-status species and allow for a biological preserve which would permanently preserve large habitat blocks within Butler Ranch totaling approximately 240 acres.
