CNPS Chapter-Based Rare Vegetation
Sampling/Mapping Workshop

Saddle Creek North, Orange County  
June 8-9, 2013

The CNPS Vegetation Program is conducting a field-based sampling/mapping workshop in Orange County at the Saddle Creek North property, which is managed by the Conservation Fund. This property is located near the intersection of Santiago Canyon Road and Live Oak Canyon Road (near “Cook’s Corner”).

This two day workshop will focus on techniques to identify and survey rare natural communities using our combined CNPS/CDFW protocols. The overall goals of the workshop are to learn about the vegetation on site, learn to identify discrete stands of vegetation and estimate percent covers, and become familiar with the Relevé method for sampling vegetation. We will also discuss low-tech options for contributing to vegetation mapping efforts.

The property is diverse and will allow sampling of scrub oak chaparral and coast live oak woodland. Other vegetation types we hope to sample include coastal sage scrub and cactus scrub.

The cost of the workshop is only $25 for CNPS members and $70 for non-members, which includes a one-year membership to CNPS. The precise meeting location, agenda, and options for lodging (with specifics on camping, hotels, and important items to bring) will be posted at

If you are able to attend, please RSVP to Deborah Stout () no later than Friday May 24, 2013 if possible, so that we can arrange travel plans and other specifics. The Vegetation Program staff looks forward to meeting and working with the Orange County Chapter members!

Workshop Goals:

  • Provide tools to chapter members and the public to sample/ map vegetation in priority areas that need additional inventory
  • Use existing CNPS/DFG Relevé and Rapid Assessment protocols to collect new data on rare vegetation types
  • Use aerial photos to discuss mapping of rare vegetation and other special features
  • Discuss how data can be utilized in conservation planning
