Objectives

Target Audience: Professional and student botanists, ecologists, resource managers, and conservationists. Participants should have an initial understanding of the subject matter and basic plant identification skills.

Full Description: This course will be a combination of lecture and field exercises in vegetation sampling with a focus on collecting data using the CNPS-CDFW combined vegetation rapid assessment and relevé methods. We will discuss applications of fine-scale vegetation sampling, classification, and mapping, how to document rare natural communities, and how vegetation information fits into planning documents.

To earn a certificate of completion, participants will need to successfully complete two vegetation rapid assessment field forms on the final day.

Participants will learn:

  • Applications of fine-scale vegetation sampling, classification and mapping
  • How vegetation sampling is used for mapping projects
  • How to collect data using the CNPS-CDFW combined vegetation rapid assessment/relevé method
  • How to document rare natural communities
  • How vegetation types and attributes can be mapped
  • How vegetation information fits into County General Management Plans, CEQA, HCP’s, NCCPs, etc.
