September 15, 2022 - Forestry topic information sheet provides program information about the Logger Best Management Practice (BMP) Cost-Share Program providing cost-share assistance to loggers for installation of best management practices.
September 14, 2022 - Report proivdes results from a series of four studies of tree-of-heaven control using triclopyr ester applied at different times during the year by basal spray or cut stump application methods. A mixture of 25% triclopyr ester herbicide in an oil-based carrier achieved excellent tree-of-heaven control for trees up to 16 inches in diameter.
September 14, 2022 - Report provides results from a study of the effects on loblolly pine growth of five hardwood competition control strategies (pre-plant site prep, year-one release, year-two release, one-year layout followed by pre-plant site prep, and no control). After five years, all treatments had effectively controlled hardwood competition and differences in pine growth were directly related to the timing of hardwood control.
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.
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.
Evaluating Initial Responses of Natural and Underplanted Oak Reproduction and a Shade-Tolerant Competitor to Midstory Removal
August 11, 2022 - This study describes growth 6 years after mid-story removal of planted and natural black oak, northern red oak, and white oak, and natural red maple competition. Article by Jared M. Craig, John M. Lhotka, Jeffrey W. Stringer, Society of American Foresters. Forest Science, Volume 60, Issue 6, December 2014, Pages 1164–1171.

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
