Report provides a brief history of longleaf pine in Virginia, the original range of longleaf pine, longleaf and fire, the search for native longleaf pine, the case for conserving and restoring Virginia’s longleaf pine, the importance of Northern-source seedlings for longleaf pine restoration, seed collection and seedling production, orchard development, where we are restoring longleaf pine, special programs available to promote the restoration effort, and future goals and challenges. Printed copies available.

The Virginia Department of Forestry (DOF) and the Meadowview Biological Research Station (MBRS) recently acquired land that expands an existing conservation easement on the Joseph Pines Preserve in Sussex County. The 196-acre purchase by MBRS increases the preserve property to nearly 428 acres. The easement, donated to DOF by MBRS, includes the entire preserve.

Report provides an update on the effects of planting date on longleaf pine survival in Virginia.

Report provides 10-year results from a study comparing the survival and growth of longleaf pine seedlings from Alabama, Florida, Georgia, Mississippi, North Carolina (two sources), South Carolina, and Virginia. Primarily due to earlier growth initiation and better survival, the Virginia source produced significantly more volume per acre and ranked higher in fitness score than the other provenances.

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.

Report summarizes field data gathered in Orange County, VA in shortleaf and loblolly pine plantations.

Report provides growth data from a 1937 Buckingham County plantation containing both loblolly and shortleaf pine that was thinned at age 19 and again at age 24, providing evidence of the more rapid growth of loblolly pine.

Report provides first-year results of a study to test spot seeding as a method of establishing loblolly, Virginia and shortleaf pine on cutover land.

Report summarizes a three-year study of planting survival of loblolly, shortleaf and white pine, including more than 3,300 different plantings.

Report provides results of a 1967 study to compare flowering dates of the different genetic lines of loblolly and shortleaf pines in the DOF seed orchard at that time.

Report summarizes yield data from 57 shortleaf pine stands in 40 different plantations in 25 different piedmont and mountain counties.

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.
