Rare Plant Communities Initiative Update

In early February, 2011, CNPS Vegetation Program staff conducted a field-based workshop in the Sonoran Desert of eastern Riverside County. This workshop focused on identifying, surveying, and mapping of rare vegetation. The workshop’s main goals were to learn about the desert’s diversity of vegetation types, highlight areas containing rare plant communities, and discuss ways for CNPS Chapters and others to contribute surveys/mapping in priority areas.

Approximately 20 participants gathered for this workshop around Palen Lake near Desert Center. Palen Lake is an alkali playa surrounded by series of active, semi-stabilized, and stabilized dunes and areas of desert pavement. It includes a myriad of vegetation patterns including creosote shrublands, mesquite bosques, desert wash woodlands, saltbush scrubs, and groundwater-dependent sink scrubs in addition to the dune and desert pavement habitats. Participants included individuals from the Kern, Los Angeles/Santa Monica Mountains, San Diego, and San Gabriel Chapters of CNPS, as well as college students and biological consultants. Also in attendance were representatives from the Bureau of Land Management’s Palm Springs/South Coast Field Office.

During the workshop, we sampled 15 vegetation stands and made several additional observation points. CNPS staff person, Deborah Stout, remained on site for a couple additional days of sampling and mapping. Rare communities included Parkinsonia florida (blue palo verde), Olneya tesota (ironwood), Propopis glandulosa (mesquite), and Psorothamnus spinosus (smoke tree) woodland alliances; and Suaeda moquinii shrubland (bush seepweed) alliance.  Stand locations have been plotted in GIS, and we entered the survey data into our ever-expanding Access database for future classification and mapping efforts.

Several participants are interested in leading follow-up trips to survey rare vegetation in their local areas, and CNPS staff is thrilled to receive correspondence from participants asking for additional information and support. This workshop provided a wonderful opportunity to meet and work with Southern California chapter members, and to continue developing our rare plant communities initiative. CNPS extends special thanks to BLM staff for use of their 4WD vehicles. This workshop was supported in part by a private bequest to CNPS, and we are looking for additional funds to continue this important work.

Fen Vegetation Assessments

The CNPS Vegetation Program, in partnership with US Forest Service Region 5 and UC Davis, has completed a classification and mapping report on fen vegetation and related wet meadows for 3 locations of the Shasta-Trinity National Forest (NF). We will continue mapping of fen/wet meadows for this NF later this year.

We are also in the process of finalizing a report that assesses fen vegetation throughout the entire Sierra Nevada region. An overview poster of this assessment was presented by CNPS staff during the January 2011 Northern California Botanists Symposium. You can view both the Shasta-Trinity fen report here and the overview poster by clicking here.

Vegetation Mapping in the Northern Sierra Nevada Foothills

CNPS has been working with the Department of Fish and Game and Aerial Information Systems to produce a detailed vegetation map of the northern Sierra Nevada foothills, an area of approximately 2.6 million acres.  The entire map has been completed and will be posted online along with a vegetation mapping report by March, 2011.  For more information, please click on this link


Updated Natural Community List Now Available


Our partners at the Department of Fish and Game’s Vegetation Classification and Mapping Program (VegCAMP) have recently updated the state “Natural Community List”.  The VegCAMP website provides a link to background information and to the current list of Alliances and Associations (per A Manual of California Vegetation, Second Edition, Sawyer et al. 2009). The use of this standard vegetation classification system will enable more unified habitat assessments and conservation efforts across California.
