Ash Tree Inventories

  • Ash inventory in Bennington

One of the most important steps in preparing for a tree pest infestation is to conduct a community tree inventory to determine the potential risk to your community’s urban forest resource.  These inventories can be species-specific, focused solely on ash for emerald ash borer preparedness plans, or all inclusive, as resources and time allow.

At a minimum we recommend you examine ash trees in high use areas (such as town greens, schools, playgrounds and dense residential areas), high use roads (such as Class 1 roads, some Class 2 roads, and emergency access routes), and around emergency facilities.

  • Size
  • Location
  • Any significant ash shade trees in good health that you may want to preserve with an insecticide.

Depending on the scope of your inventory, the survey can be completed relatively quickly and efficiently by in-house staff, volunteers with minimal training, or professionals. 

Visit the Vermont Forest Pest Planning Case Studies page to learn how nine Vermont communities inventoried their town’s ash trees and developed an Emerald Ash Borer Preparedness Plan. These towns varied widely in population, size, and resources, which makes each town’s experience and lessons learned unique.
