On behalf of Waynesboro Parks & Recreation, Trees Virginia, and the Virginia Department of Forestry, we are pleased to present the 21st annual Waynesboro Tree Workshop: Reveling in the Magnificence of Trees and ArborMaster Training. The workshop is divided into two tracks, ArborMaster and Lecture. The ArborMaster track teaches hands-on techniques and skills vital for tree climbers, groundsmen, and anyone in the production side of tree work. The lecture track is divided into two sessions of indoor lectures and outdoor demonstrations and is geared towards those working in municipalities, government agencies, and private industry. There is something for everyone at this workshop and regardless of track, you will be hearing from arboriculture and urban forestry experts. 

Workshop Morning Lectures (indoors at best western)


Virginia Big Tree Program: Sharing Stories of Arboreal Giants~Dr. Eric Wiseman

The Virgina Big Tree Program has a 45-year history of documenting the largest specimens of native and non-native tree species found in Virginia. The Virginia Big Tree Register and its online searchable database comprises over 1,300 trees and boasts over 60 national champions, the fourth largest total in the country. In this presentation, you will learn about the history and mission of the Virginia Big Tree Program, how it is administered, and what you can do to support the program's cause. 

Arboriculture's "Most Wanted" List- tree killers on the loose ~ Dr. Gretchen Pettis

The number of invasive insects entering and subsequently spreading through urban forests is on the rise. Knowing which ones are critical threats and what symptoms and signs to look for could be the key to saving and preserving valuable landscape trees. Find out the latest on emerging insect pests of concern, methods of detection, and means to fight them. 

A Diamond in the Rough: Selecting young trees which will become gems of the urban forest... a growers perspective ~ Mike Worthington

How do nurseries manage plant growth to produce structurally sound trees? What should you look for when selecting or inspecting trees? What are the differences between container and field-grown trees? What trees are finding favor with wholesale nurseries and what trees are seeing increased disease and insect pressure? A wholesale grower shares his views on these topics and more. 

Stormwater Regulations and Tree Canopy: A Local Perspective ~ Keith Cline

Our urban and community forests make a significant contribution to water quality and stormwater management. But what are those contributions and how can we quantify their value? Although the science and understanding of the impact of trees and tree canopy on rainwater flow and volume is fairly well established, the water quality benefits of tree canopy are not as well documented or as clearly defined and accepted by state and federal regulatory agencies.  In this presentation, I discuss the process of incorporating urban trees and forests into the Environmental Protection Agency and state regulatory requirements under the Clean Water Act, including Municipal Separate Storm Sewer System Permits (MS4) for stormwater discharge into surface waters and Total Maximum Daily Load (TMDL) Action Plans for impaired waters. 


Workshop Afternoon Demos (outdoors at ridgeview park)

Nominating and Measuring Big Trees ~ Dr. Eric Wiseman

Virginia Big Tree Program Coordinator Eric Wiseman will discuss and demonstrate the tools and techniques for nominating and measuring big trees for the Virginia Big Tree Register.

20/20 (Pest Scouting) Vision ~ Dr. Gretchen Pettis

There are known signs and symptoms characteristic of specific insect pests. Dr. Pettis will demonstrate efficient and effective pest scouting methods and techniques to help you hone your diagnostic skills to improve plant health management. 

Creating Good Branch Architecture ~ Mike Worthington

Mr. Worthington will demonstrate techniques for pruning young trees to improve their overall structure. 

Stormwater Solutions: the Ridgeview Park Example ~ Tony Smith/Keith Cline

Take a closer look at a parking lot retrofitted with stormwater enhancements- what was the problem, what was the remedy, what are the ongoing challenges.
