November 3, 2020 - Report provides results from diameter monitoring plots in 32 black walnut stands scattered over the piedmont and mountain regions of Virginia and 57 black walnut planting study sites.
November 3, 2020 - Report provides information about a study where loblolly pine seedlings were planted in rows that had either been ripped to a depth of 16 inches or not ripped on eight different tracts. At age six, neither survival nor height were significantly affected by treatment, but the gain in diameter of 0.13 inches was statistically significant.
November 3, 2020 - Report provides results of the effects of top-clipping treatments on loblolly pine seedlings with varied root collar diameters in the nursery and field (through age three).
November 3, 2020 - Report provides seven-year results from two studies comparing varying rates of nitrogen fertilizer applied loblolly pine seedlings in the nursery seedbed. Nitrogen rate did not have any effect on survival or growth of the seedlings seven years after planting.
November 3, 2020 - Report provides 20-year results of a comparison of seedlings from five open-pollinated loblolly pine parents sown either separately or randomly mixed in the nursery bed. Survival was not affected by sowing pattern, but at age 20, the randomly-mixed seedlings were taller than those sown in pure lots and there were differences among genotypes.
November 3, 2020 - Report summarizes yield data from 59 plots installed in 48 different white pine plantations over a 30-year period that was used to construct volume tables and site index curves and project board-foot volumes.
November 3, 2020 - Report provides 15-year growth information on three locations of plots in the piedmont of Virginia planted with 200, 300, and 400 loblolly pines per acre. This study demonstrated that relatively low-density plantings of loblolly pine can result in well-stocked stands capable of supporting a merchantable thinning by age 15.
November 3, 2020 - Report summarizes past studies and results from a new test of varied storage times, exposure during grading and planting, and transport. Survival ranged from 46% to 91% and was reduced by cold storage over four weeks when combined with prolonged exposure during planting and exposure during transportation.
November 3, 2020 - Forestry topic information sheet provides information about possible control treatments for some of Virginia’s most common non-native invasive plant species.
November 3, 2020 - Brochure provides an overview, as well as detailed fire law information in the Commonwealth of Virginia, encouraging citizens to know the forest fire laws and local ordinances before burning, and safety tips for burning. Printed copies available.
