Abstract

In parts of Pennsylvania, oak regeneration after harvest cutting or natural disturbances has been very poor. Studies on the Tuscarora State Forest suggest that the primary cause of natural regeneration failure may be a lack of viable acorns; on some sites acorn insects and rodents destroy nearly all acorns, even in good seed years. Artificial regeneration is not without difficulties either: rodents were able to reach direct-seeded acorns even through plastic protectors; and planted seedlings have been severely damaged by deer browsing.
