    Description

    The effects of small mammals on surface-sown northern red oak (Quercus rubra) acorns was assessed in highly productive Appalachian hardwood stands. Study plots were established in October 1990 on excellent (average site index of 89 feet for red oak) and good (average site index of 72 feet) sites. Each plot included: 1) a rodent-proof exclosure, 2) an exclosure accessible only to small rodents, and 3) a non-enclosed open quadrat. By comparing the survival of acorns on the rodent-accessible quadrats with that on the open quadrats, it was determined that small rodents have a highly significant effect on the acorn crop. Of the 360 acorns placed in the open, only 10 survived until June. Only seventeen of 360 survived on the partially enclosed quadrats. It was determined through snap-trapping that white-footed and deer mice (Peromyscus spp.) were primarily responsible for removal of the acorns from the partially enclosed quadrats. In addition, it was determined through the use of regression analysis that small rodent damage to the acorn crop was greatest in stands that included small snags and large non-red oaks in the upper canopy.
