New Hampshire’s Forest Health: Insects and Diseases workshop

UNH Extension

UNH Extension will hold a New Hampshire’s Forest Health: Insects and Diseases workshop at Southeast Land Trust’s Burley Farms property in Epping, NH on September 15th from 8:30 am to 3:30 pm

During this all-day, “in the field” workshop, small groups will rotate through six stations at Burley Farms. At each station there will be a unique set of insects, invasive plants, or diseases that a specialist will show you, let you handle, and then moderate a discussion of how these pests could influence your forest or habitat management.

Bring your own samples or pictures of pests or damage you’re seeing in the woods and our experts will ID them. Gather that weird forest insect or damage and stump the experts!

Station 1:  Defoliators. Kyle Lombard, Forest Health Coordinator, NH Division of Forests and Lands.

A session looking at examples of the most common forest defoliating insects in NH. Some of the pests included will be saddled prominent, forest tent caterpillar, Lymantria dispar, frost damage, maple leaf cutter, oakleaf skeletonizer, fall webworm, spruce budworm, and balsam woolly adelgid.

Station 2: Beech leaf disease, beech bark disease, and various other pathogens. Cameron McIntire, Plant Pathologist, US Forest Service.

Cameron will show signs and symptoms of beech leaf & bark diseases – a discussion of an old beech problem and a new one.  Other pathogens impacting our common trees will be presented with silvicultural options for mitigating these pathogens’ impact on growth and health.

Station 3: Hemlock Wooly Adelgid and hemlock issues. Ryan Crandall, Forest Health Specialist, NH Division of Forests and Lands.

Ryan will share his expertise with HWA and discuss the status of this well-established pest in southeastern NH and efforts to monitor and control HWA. Other pests such as elongate hemlock scale, hemlock borer, and others will be discussed.

Station 4: “What is that?” Dode Gladders, Sullivan County Extension Forester.

Back by popular demand, Dode will have hands on samples of all those insects and diseases you walk by in the woods and say, “what is that?” Stuff like pine bark adelgid, leaf galls, sugar maple borer, and oh so much more.

Station 5: Emerald Ash Borer. Bill Davidson, Forest Health Specialist, NH Division of Forests and Lands.

At this stop Bill will have samples of various life stages of EAB, damaged ash trees, and examples of blonded ash trees. Topics include silviculture recommendations, pesticide options, survey methods, quarantine requirements, and bio-control programs.

Station 6: Upland invasive plant species. Steven Roberge, Extension State Forestry Specialist.

Steve will have samples of invasive plants for you to get familiar with to heighten your identification skills and options for treatment and control. He will also discuss species that are close by and would benefit from “early detection/rapid response” management.


Cost of this workshop is $20 per person.  Participants should bring their own lunch.
