Scientists typically publish research results in scientific journals in formats, language, and styles that are not always useful to many professional and general public users. To address this gap in technology transfer, we developed a method to get research published in journal articles out to a broader spectrum of users. This paper uses a study of oak regeneration to illustrate how scientific ...

We compared the initial effects of four forest regeneration treatments (single-tree selection, group selection, shelterwood, and clearcut), and unharvested controls (mature, second-growth forest) on relative abundance of small mammals and smallmammal habitat throughout the Ouachita Mountains of western Arkansas and eastern Oklahoma. We compared small-mammal capture rates in 20 forest stands (4 ...

We compared indices of total hard mast production (oak and hickory combined) in 20, secondgrowth, pine-hardwood stands under five treatments to determine the effects of different reproduction treatments on mast production in the Ouachita Mountains. We evaluated mast production in mature unharvested controls and stands under four reproduction cutting methods (single-tree selection, group selecti...

Many mixed hardwood stands found in bottomlands have been degraded by past harvesting practices that resulted in high grading the stand, thereby leaving the forester few options other than regeneration. Economic considerations usually constrain the choices to some form of complete overstory removal if adequate advance regeneration or sprouting potential is available. Success, in terms of number...

Partial cutting is thought to be an alternative to achieve sustainable management in boreal forests. However, the effects of intermediate harvest intensity (45%–80%) on growth remain unknown in black spruce (Picea mariana (Mill.) B.S.P.) stands, one of the most widely distributed boreal species with great commercial interest. In this study, we analysed the effect of three experimental shelterwo...

David S. Dyson Longleaf Pine

Longleaf pine once was present on 90 million acres of the southern landscape, ranging from coastal Virginia to east Texas and from central Florida to the mountains of Alabama. On nearly two-thirds of that area, longleaf pine grew in nearly pure (single-species) stands maintained by frequent, low-intensity surface fires of both natural and human origin. The remaining one-third of that area was s...

Eastern white pine (Pinus strobus L.) is a cultural keystone tree species in the forests of eastern North America, providing numerous ecosystem services to Indigenous people. White pine abundance in the landscape has considerably decreased over the last few centuries due to overharvesting, suppression of surface fires, extensive management, and plantation failure. The Kitcisakik Algonquin commu...
