Recent Research/Educational Projects:
Damage to Pennsylvania Agricultural Crops by Wildlife Wildlife, primarily white-tailed deer, damage agricultural crops. The intensity of damage varies by crop type, spatially and temporally. We have developed a sampling strategy and allocation scheme to provide unbiased county estimates of damage for two high-value crops, corn and cabbage. Statewide sampling will begin during the 1995 growing season.
White-tailed Deer Effects on Regeneration of Mixed-Oak Forests on Public Lands Effects of canopy opening and white-tailed deer on vegetation are being assessed in south-central Pennsylvania. Three levels of canopy openings were created March 1993 in three woodlots. Deer exclosures were established on one-half of the inventory plots. Herbaceous plants and woody seedlings were inventoried prior to treatment. Post treatment inventories are being conducted.
