IES - Gypsy Moth Plot Tree
||To assess the role of habitat differentiation in gypsy moth
population dynamics - (focal area).
||4 sites: Pachaug State Forest North Stonington, CT.
Otis AFB, MA.
Bryant Mountain, Salisbury, VT.
Harvard Black Rock Forest, Cornwall, NY.
VT:15 banded plots and 15 unbanded plots.
NY:15 banded plots and 35 unbanded plots.
MA:16 banded plots and 21 unbanded plots.
CT: 16 banded plots and 16 unbanded plots.
|Likelihood of Locating Study Areas:
||None besides natural defoliation from gypsy moths.
||Bryant Mountain, Vermont was monitored from 1983 to 1991 while
other sites were disbanded before 1991. Vegetation was data
collected once and updated periodically. Except for wing measurements,
the same variables were measured for the life of the study.
|Variables and Sampling Frequency:
||All stages of the gypsy moth:
Egg mass: pre-hatch counts: 1985-1988. post-hatch counts: 1984-1987.
Lab egg oviposition: 1982-1987.
Larval count: 1984-1988.
Pupal tally - low density: 1984-1988.
Pupal tally - high density counts: 1984-1988.
Vegetation: tree sp., d.b.h., height, canopy height, basal
area in square meters: 1984.
||proofread data before and after computer data entry. Proofread
output analyses (charts and graphs) for trends.
||Raw data resides on the Data General computer both in ASCII
format and in the Oracle database. All of the data, including
summaries, is located at the USDA Forest Service in Hamden,
CT. The information will be transferred to the new Forest Service
computer platform during fiscal year 1998.
