Calling all site plan reviewers, landscape architects, arborists, grounds staff, environmental planners, and property managers! Want to spend a hands-on and dirty day excavating tree roots of all sizes growing in various growing conditions? Join us for a day of studying the intricacies of roots! If you don’t want to get hands on, not a problem – you’ll still learn tons! Make sure to dress for the weather! Bring your own tools, such as a hand trowel, garden fork, long handled or short handled pointed shovel, or brush to expose finer roots.

The moderator and originator of root appreciation day workshops since 1991 is Chris Cowles, MD RPF, Senior Urban Forestry Consultant, Wetland Studies and Solutions, Inc.

Special thanks to Vincent Verweij, Urban Forest Manager for Arlington County for hosting and Wetland Studies & Solutions, Inc. for preparation support.
