Book Description
S2Bark beetles, primarily the peach bark beetle, Phlosotribus liminoris (Harris), are the major cause of gum spots in sawtimber-size black cherry, Prunus serotina Ehrh. Approximately 90 percent of all gum spots in the bole sections are caused by bark beetles. Gum spots were studied in 95 black cherry trees near Parsons, West Virginia. Over 50 percent of the bark beetle-caused gum spots occurred during the first 2 years following partial harvest cuts. Cambium miners, Phytobia pruni (Gross), peach tree borers, Synanthedon pictipes (Grote and Robinson) and S. exidiosa (Say) caused little degrade in the quality zone of veneer logs or in factory grade 1 and 2 sawlogs. S3.

Factors Affecting Recreation Participation by Vermont Residents

Category : Recreational surveys
Languages : en
Pages : 522
Book Description
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.
