Maintenance of oak species and a lack of oak regeneration are major silvicultural problems in many upland oak forests of the Eastern United States. Advance oak regeneration where present generally is small and lacks vigor. As a result, artificial regeneration is sometimes used, but planted oak seedlings usually do not grow well. Plastic tree shelters have been used to protect planted and natural oak seedlings from deer browsing and to promote seedling height growth and survival. This study examined the growth and survival of planted and natural red oak seedlings and seedlings from planted acorns within translucent tree shelters, fences, and unprotected controls with and without herbicide application under a shelterwood seed-cut stand. After 2 years, surviving control planted seedlings were significantly shorter than those protected by tree shelters and fences. The average height of seedlings planted within tree shelters and fences was 0.88 foot and was not significantly different. Planted control seedlings were shorter after the second year than the first, suggesting that these unprotected seedlings had been browsed by deer. The best survival of planted seedlings was inside the fences, with and without herbicide. Survival in shelters was 82 percent when herbicide was used and 40 percent without herbicide, probably due to low light intensity. Survival of planted control seedlings was unsatisfactory whether or not herbicide was applied, likely the result of browsing. Only 16 percent of the acorns planted within shelters produced seedlings and none grew outside of shelters. Small mammals destroyed most planted acorns. Natural seedlings grew little and their height inside and outside of shelters was not different from that of planted seedlings. Recommendations based on these results should improve results when tree shelters are used.

S2In West Virginia, yellow-poplar (Liriodendron tulipifera) is abundant and is a prime candidate for increased utilization in a variety of manufacturing industries. Computer simulations are a cost-effective tool for estimating potential cutting yields from lumber. They can be used to promote increased use of yellow-poplar in the furniture, cabinet, and architectural woodworking industries and may also lead to increased utilization of the lower grades of lumber. This paper describes the data collection methods and the format of the new West Virginia yellow-poplar lumber defect database that was developed for use with computer simulation programs. The database contains descriptions of 627 boards, totaling approximately 3,800 board feet, collected in West Virginia for grades FAS, FASIF, No. 1 Common, No. 2A Common, and No. 28 Common.S3.
