Annual Vermont Forest Health Highlights (2019) is Available

Vermont Forest Health Highlights for 2019 are now available online.

A few highlights from the highlights:

  • Emerald ash borer (EAB) has now been confirmed in eight counties. Parts of five additional counties are also within the mapped area considered to be at risk. Any ash within the mapped area should be treated as if it may be attacked by EAB in planning for management, removal, or utilization. Infested area maps, recommendations for management and for slowing the spread of EAB, and links for reporting suspect trees are at

  • Based on acres defoliated and moth trap counts, the forest tent caterpillar outbreak is drawing to a close. We continue to see sugar maple decline and mortality, incited by forest tent caterpillar defoliation, which was mapped on over three thousand acres, with dry weather likely to have contributed to the decline.

  • The Forest Biology Lab moved to the new Vermont Agricultural and Environmental Laboratory on the campus of VTC in Randolph.
