This paper discusses opportunities for timber utilization improvement that will 1) increase efficiency of wood use, 2) reduce the cost of wood products and the cost of using wood in applications, and 3) provide new or improved wood products or wood use applications. A key purpose here is to propose…

Surface soil disturbance was compared among a commercial thinning, group selection, patch cut, 2-age, and clearcut. The thinning, group selection and patch cut units had significantly higher percentages of undisturbed area. The 2-age unit had a significantly higher percentage of area disturbed with…

Estimates of the amount of nutrients removed by dormant-season harvests of coppice American sycamore indicated that harvesting once (at age 4) or twice (at ages 2 and 4) removed 20-145 kg/ha of N, P, K, Ca, and Mg and small quantities of Mn, Zn, Fe, and Cu. Calculations of nutrient drain indicated…

In recent years, nonpoint source pollution (NPS) has been recognized as one of the major threats to the nation's water quality. Clearly, forest operations such as harvesting and site preparation have the potential to have degrading impacts on forest water quality. However, there exists a gap in the…
