The introduction of exotic pests significantly impacts the health of our forests. The health of eastern hemlocks is threatened by both hemlock woolly adelgids and elongate hemlock scales, both native to Asia. Use of systemic insecticides has been critically important for conservation of hemlocks, both in the Delaware Water Gap National Park and in the Great Smoky Mountains National Park. These insecticides provide a stop-gap measure to preserve stands of hemlocks until effective natural enemies are established. This work aims for long-term conservation of the genetic stock that they represent. Dr. Cowles will describe the methods used in these parks for conservation of hemlocks, optimization of treatments, and also in determining the degree of environmental contamination resulting from these actions. While the current outlook has improved for hemlocks in these sites, long-term global climate change may overwhelm these conservation efforts.
Our own Northwest Camp is located in a stand of Hemlocks and would lose much of it's beauty if these trees were lost.
Dr. Richard Cowles obtained his undergraduate degree from Cornell, and his graduate degrees from Michigan State. After a stint as the statewide extension and research ornamentals and turf specialist for California, he came to work at the Connecticut Agricultural Experiment Station. For the past 22 years, he has been working to find appropriate solutions to insect, mite, and disease problems in turf, small fruits, forests, and Christmas trees.
