Medium-density fiberboards of acceptable quality were made from a mixture of barky chips from 14 southern hardwoods. Boards made from fiber refined at three different plate clearances did not vary significantly in bending, internal bond (IB), or linear expansion. But, lack of replications and the fact that the refiner was not loaded to capacity caused these results to be inconclusive. Increasin...

In natural stands, trunk borers are economically the most serious insect pests. The larvae construct galleries in the trunks of living trees, causing the greatest damage in the lower portion (Beal 1952; Hay and Wootten 1955). The quality of the butt log, which is potentially the most valuable portion of the tree, is greatly reduced. Oaks suffer more damage than other hardwoods in the South (Hay...

Fiber development in pulp refining can be characterized by three parameters: number of impacts on pulp, N; energy per impact, I, and bar force fibers, F. These parameters enable comparisons radically different conditions; determination intensity for hardwoods softwoods; assessment effect width fiber shortening; predictions tensile strength increases.

Dynamic zoning (systematic alteration in the spatial and temporal allocation of even-aged forest management practices) has been proposed as a means to change the spatial pattern of timber harvest across a landscape to maximize forest interior habitat while holding timber harvest levels constant. Simulation studies have established that dynamic zoning strategies produce larger tracts of interior...
