S2Damaged germinating northern red oak, Quercus rubra L., acorns in pitfall traps were significantly more attractive to two species of acorn insects than undamaged germinating acorns. Significantly more adults of the weevil Conotrachelus posticatus Boheman and the sap beetle Stelidota octomaculata (Say) were caught in traps containing germinating acorns cut into halves versus traps containing uncut, germinating acorns. Larvae of the acorn moth Valentinia glandulella (Riley) also preferred damaged over undamaged acorns, but few larvae were caught and the results were not analyzed. S3.

S2Appalachian hardwood stands in West Virginia were managed for 30 or more years using single-tree selection regeneration practices. Stand yield data suggest that current stand growth will provide economical harvest cuts for several future cutting cycles. This case study indicates that single-tree selection has potential for landowners who want to maintain continuous overstory cover and are willing to accept the gradual species shift to more shade-tolerant species.S3.

Long-term recreation planning requires an understanding of recreation participation patterns. This study examined Vermonters' participation in 27 leisure activities from three domains (outdoor, resource based, and indoor) to see how such participation differed in each domain. Indoor activities were the most popular, followed by resource-based activities and general outdoor activities. Overall participation declined with age, though this effect was mitigated somewhat for older parents. Other socioeconomic and demographic variables had limited effects on participation.
