Urban tree monitoring: A field guide

This report provides detailed protocols for urban tree monitoring data collection. Specifically, we discuss the core variables necessary for field-based monitoring projects, including field crew identification, field crew experience level, tree record identifier, location, site type, land use, species, mortality status, crown vigor, and trunk diameter. The intent of this Field Guide is to serve urban forest managers and researchers who collect longitudinal field data on urban trees, as well as interns and citizen scientists. This report is a companion document to Urban Tree Monitoring: A Resource Guide.
