No. 143 Site Prep vs. Release for Woody Competition Control in Loblolly Pine: 15-Year Results

September 14, 2022 - Report provides age 15 results from a study of the effects on loblolly pine growth of seven herbicide alternatives for hardwood competition control (all with and without an additional year one herbaceous weed control treatment). After 15 years, pine productivity increased by 70% with the best site prep treatment compared to 40% with a second-year release.

No. 142 Five-Year Effects of Herbicide Tank Mixes and Surfactants for Loblolly Pine Release

September 14, 2022 - Report provides results from a study of the effects of five surfactants when applied with three common herbicide mixes for loblolly pine release. Pine damage was associated with the Arsenal (imazapyr) x Accord (glyphosate) tank mix – either with or without surfactants – and was temporary. Five-year pine growth was significantly better with release despite the damage.

Fire Adaptive Landscaping for Native Habitats and Wildlife in the Southern Coastal Plain

April 27, 2022 - Book was prepared by the Georgia Forestry Commission, U.S. Fish and Wildlife Service, Coastal Wildscapes, and Firewise Communities to provide every resident and business owner has the opportunity to enhance wildlife habitat and natural ecological systems by maintaining, or where necessary, restoring connectivity to the surrounding forests and other natural communities through landscaping and gardening activities. They can also address the very important issues of water conservation and loss of... Read More

Crop Tree Release Improves Competitiveness of Northern Red Oak Growing in Association with Black Cherry

April 19, 2022 - In 1993, a crop tree study was established in a pole-sized stand consisting of black cherry (Prunus serotina Ehrh.) and northern red oak (Quercus rubra L.). Ten-year mean height growth of northern red oak exceeded that of released black cherry, but not that of unreleased black cherry crop trees. Crown expansion and diameter at breast height (dbh) growth also increased as a result of crop tree release for both species,... Read More

Effect of Thinning on Height and Diameter Growth of Oak and Yellow-Poplar Saplings

April 19, 2022 - Studying the response to thinning of a 7- to 9-year-old upland hardwood sapling stand, we found that height growth of yellow-poplar and oak trees was markedly reduced by heavy thinning. This suggests that stand density should be carefully controlled to achieve maximum benefit from thinnings in very young stands. By Rufus H. Allen, Jr. and David A. Marquis.

Intensity of Precommercial Crop-Tree Release Increases Diameter and Crown Growth in Upland Hardwoods

April 19, 2022 - In 1988, seven study areas were established in Connecticut to examine the effects of precommercial crop tree release on bole and crown growth. Relative to unreleased trees, 4-yr diameter growth of northern red oak increased by 86%, black/scarlet oak by 65%, red maple by 56%, and black birch by 52%. Release slowed height growth of dominant and codominant oaks for only the first 2 yr. In sapling stands with few... Read More
