Gypsy Moths are a permanent resident of the park. They were first discovered in the park during the winter of 1983-84, and prey primarily on Oak trees. The good news is that these bugs are now controlled by other parasites, disease and predators.
Another dangerous insect to the park is the Hemlock Woolly Adelgid. These bugs, first spotted in Virginia around 1950, suck the sap from the base of young needles, which can stunt new growth and even kill mature needles. Park biologists have joined with other agencies to develop ways for controlling this parasite. However, to date they have had no success.
Prescribed burns
Fires will be deliberately set in the park periodically, mostly to control the accumulation of vegetation and dead wood. “There is a benefit to burning,” said Ms. Rothgeb. Problems can arise, however, when the weather doesn’t cooperate.
In the spring, a controlled fire in the south portion of the park got out of control due to an unexpected change in the weather. Instead of rain, they received stiff winds. The Park Service, however, feels that controlled fires are safe and will continue to use them as a method of vista management.
