Target Audience: Professional botanists, ecologists, land managers, resource specialists, and conservationists.

Description: Using classroom and field exercises, the workshop will focus on the role of plant population monitoring for adaptive management. Participants will learn how to develop good management objectives. Topics cover principles of sampling and several sampling designs, field techniques for measuring vegetation, analysis of monitoring data, and presentation of results. Participants will receive a copy of the BLM-published book, Measuring and Monitoring Plant Populations by Caryl Elzinga, Dan Salzer, and John Willoughby, a binder with all of the material presented at the workshop, and a CD containing helpful computer programs, papers, and other materials.

Participants can expect to:

  • Acquire a higher level of knowledge and confidence in monitoring plant populations
  • Learn the two basic types of management objectives and the tools you can use to develop good objectives
  • Understand the principles of sampling and the importance of setting good sampling objectives for monitoring studies that involve sampling
  • Learn about the most common sampling designs used to monitor plant populations and when each design is appropriate
  • Become more familiar with the field techniques used to measure plant populations in the field and their advantages and disadvantages
  • Understand the data analysis associated with the two types of management/sampling objectives
  • See examples of different ways to present monitoring results

About the Instructor:
John Willoughby, M.A., is a consulting botanist, recently retired from the Bureau of Land Management, where he served as California State Botanist for 28 years. He is the coauthor of two widely cited textbooks on the monitoring of plant populations and vegetation, and has instructed dozens of workshops on the subject. He served as an adjunct professor at California State University, Sacramento, for more than 20 years, and has experience and training in statistical sampling techniques, nonparametric statistics, multivariate analysis, population modeling, and remote sensing of vegetation. He has designed many monitoring studies, including one of the largest and most intensive plant monitoring efforts ever implemented, involving 10 years of rare plant monitoring in the Algodones Sand Dunes.
