Growing a rare plant mapping and floristic project with local support.

In October, 2006, the UC Davis Center for Plant Diversity initiated a local collecting and mapping project at the Bureau of Land Managementís Payne Ranch property in Colusa County, California. Several special-status plant species were known to occur on the property, yet the nearly 15,000 acre ranch had never been surveyed, lacked a plant list, and the locations of special-status species were mostly unknown. During the 2006-2007 academic year, ten field trips were carried out to prepare a specimen-based plant list and locate and map special-status species populations. Over 50 people participated in the first yearís field effort, including college students, local hikers from Yolo, Colusa, Sacramento, and Lake counties, and state and federal agency employees. Field trips were advertised via the Tuleyome Yolohikers email list serve as well as a local gardening email list serve. Volunteer curation days held the following winter (2007-2008) were advertised in local papers and attracted helpers from several counties, as well as a student service group, and these volunteers assisted in specimen databasing, mounting, and filing. The project was mentioned in local newspaper articles sponsored by Tuleyome as well as in the Center for Plant Diversity newsletter, and this helped to attract more interest. The first field trip of the current academic year on March 30, 2008 attracted 17 participants, nine of whom were new to the project, and the participants helped map several new special-status species occurrences. The plant list for the ranch is now over 400 species long, and over 25 rare plant occurrences have been mapped. The project has received funding from the National Fish and Wildlife Foundation.
