November 3, 2022 - Report provides results from a study of the effects of seedling source (NC orchard mix, GA mountain and GA coastal), competition control methods and planting depth on the establishment and early growth of longleaf pine on an old-field site. Five-year results show that the most important factor in establishment success was scalping. Shallow planting and Oustar at 8 -12 oz./acre were also helpful.
November 3, 2022 - Report provides results from three locations of a study of competition control and fertilizer treatments for establishing shortleaf pine on old-field and cutover sites. Herbaceous weed control (using herbicides or mechanical scalping) at the beginning of the first growing season improved survival and growth of planted shortleaf pine on both old field and cutover sites after two years.
October 21, 2022 - Invasions of nonnative plants into forests of the Southern United States continue to spread and include new species, increasingly eroding forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. This book provides the latest information on how to organize and enact prevention programs, build strategies, implement integrated procedures for management, and proceed towards site rehabilitation and restoration. Effective control prescriptions are provided for 56 nonnative... Read More
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 provides 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.
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.
May 26, 2022 - Forestry topic information sheet provides information about the mission and services of the VDOF Forest Utilization and Marketing Program and how VDOF works to support and promote Virginia’s forest products industry while maintaining a sustainable forest resource.
