Sat.-Sun., May 6-7, 2017: Rare Plant Treasure Hunt near Elizabeth Lake: CANCELLED BECAUSE OF FORECAST INCLEMENT WEATHER. The Rare Plant Treasure Hunt (RPTH) is an ongoing program of the CNPS begun in 2010 to obtain up-to-date information about many of California's rare plants. The program relies on participation from chapter members throughout the state. The RTPH event on May 6 and 7, 2017, is jointly sponsored by the CNPS state office, the environmental consultants WRA, Inc., and our CNPS chapter. It will focus on the Petersen Ranch Mitigation Bank, which includes two areas not previously explored by CNPS, the 4,000-acre Petersen Ranch and the 300-acre Elizabeth Lake property about 1 mile to the west. Chapter members and others are invited to participate. Participants may attend either day, or camp overnight Friday and/or Saturday. Be aware that you will be spending considerable time off trails with no facilities. Note that this is an active cattle ranch.

The leader is Catherine Curley of the CNPS state office. For details and to confirm attendance, please email Catherine at She needs to know which days you will be attending, estimated arrival and departure times, dietary restrictions (if any), what dish you can bring to the Saturday evening potluck, whether you will be camping, etc.

Background: The Petersen Ranch Mitigation Bank is the only mitigation bank in Los Angeles County, the largest in the State of California, and one of the largest in the United States. Situated within the boundaries of the proposed San Andreas Rift Zone Significant Ecological Area, it provides compensatory mitigation across a large part of Southern California. NOTE: Mitigation banking is the preservation, enhancement, restoration or creation (PERC) of a wetland, stream, or habitat conservation area which offsets, or compensates for, expected adverse impacts to similar nearby ecosystems. Petersen is the Petersen of Automotive Museum fame.
