The purpose of the California Weed Mapping Handbook is to provide resources and methods for field collection of weed observation and monitoring data that can be analyzed and shared. This is the second edition of the California Weed Mapping Handbook, first published in 2002. Materials found here are intended for weed managers looking for help designing a monitoring and data collection program as well as trainers seeking materials for weed mapping workshops.
