SUMMARY:Partner Webinar: Underplanting Longleaf Pine: The ecology behind this regeneration technique & lessons learned from a case study in Georgia
DESCRIPTION:Hosted by The Longleaf Alliance \nSpeakers: Nathan Klaus\, Georgia DNR and Dr. Joan Walker\, USDA Forest Service Southern Research Station (Retired) \nRegistration Link \nUnderplanting is the practice of introducing a new generation of trees under an existing overstory. This could be done to convert the stand to a different species\, sometimes called “conversion with retention.” It can also be done with seedlings of the same species as the overstory if a multi-aged stand is desired\, but natural regeneration is insufficient to achieve this structure. Some questions to be addressed: Why plant longleaf pine seedlings under an existing pine canopy? Is it possible to establish a longleaf pine stand without clearcutting? What preparation is needed for converting loblolly pine stands to longleaf pine dominance? How does one manage an underplanted stand to reduce damage and encourage growth? \n\n\nThis webinar has been postponed from the original date of September 26\, 2024 to November 14\, 2024. \nMany landowners are interested in restoring native longleaf pine forests for the diverse values they provide\, for wildlife habitat and recreational opportunities\, and valuable forest products and services. \nWhen landowners want to establish longleaf pine\, traditional approaches would indicate clearcutting followed by planting nursery-grown seedlings. The practice of underplanting would avoid a clearcut-and-replant sequence\, and instead favor thinning the overstory to a target basal area\, and planting longleaf under that remaining canopy. Similar goals might be met with planting in natural or created openings or gaps. \nThis approach keeps the look of a forest\, rather than the poor aesthetics of a clearcut\, an important consideration for some. \nRetaining the overstory structure is not just for looks; it provides habitat for a diversity of wildlife that may use every part of the stand from the groundcover layer to the developing sapling class of trees to the upper reaches of the canopy. \nEven if conversion to longleaf pine is desired\, an existing canopy could be providing current value that the landowner does not want to forfeit. For example\, if the loblolly stand is young\, premature harvest would reduce the landowner’s return on investment needed to establish it. \nRetaining the overstory trees also secures a fuel source in the form of pine needle litter\, allowing for prescribed burning to continue. Maintaining fine fuels to carry fire can be difficult in other replanting scenarios if the groundcover is depleted following comprehensive herbicide applications or ground disturbing site preparations. \nPart I of the program will introduce the dynamics of various canopy cover scenarios for longleaf pine regeneration\, from Joan Walker\, US Forest Service Southern Research Station (Retired). \nPart II will take viewers through an underplanting project and examine the benefits and possible limitations of this technique\, as well as provide real-world guidance for managing stand activities\, with Nathan Klaus\, Georgia Department of Natural Resources. \nQuestions will be taken by both presenters following the presentation.
