Potential defoliation by gypsy moth on Saratoga National Historic Park in 1990 - biological evaluation
Frank MS. 1990. Potential defoliation by gypsy moth on Saratoga National Historic Park in 1990 - biological evaluation
Saratoga National Historic Park encompasses 2458 acres, of which 1546 acres are forested. Severe gypsy moth defoliation could cause dieback or mortality in trees the park intends to keep or may negatively impact viewsheds. Gypsy moth egg mass surveys were conducted on the Saratoga National Historic Park on 20 August 1990. All five major Park areas had egg mass (EM) per acre estimates of less than 1000. The two trouble spots in 1989, Burgoyne's Headquarters and Fraser Burial Site, had 440 and 920 EM per acre respectively. These numbers are within acceptable limits. Overall, the population appears to be declining in the Park. It is recommended that Park personnel make informal egg mass surveys in these areas to keep appraised of any population buildup in the future.
