Effects of gypsy moth defoliation on acorn production and viability, litterfall, and litter layer depth and biomass in north-central Virginia and western Maryland
The effects of gypsy moth defoliation on acorn production (the seed
source for oak regeneration), and the forest floor regeneration
environment were investigated. Parameters measured included: acorn
quantity, weight, development, and viability; litterfall; and forest
floor depth and biomass. Nineteen plots in north-central Virginia and
western Maryland on which trees suffered heavy, moderate, or no
defoliation were monitored over a two-year period.
