Why This Research is Important
During the earlier period of timber exploitation, longleaf pine occupancy throughout the South was reduced from 93 to less than 3 million acres. Since this time, longleaf pine forests have come to be recognized as being among the most species-rich plant communities outside the tropics and yet one of the most endangered of terrestrial ecosystems in North America. In recent times, broad-scale collaborative efforts have developed which are aimed at restoring longleaf pine on several million new acres and improving the condition of longleaf pine ecosystems on many existing acres. The research undertaken by RWU-SRS-4158 "Restoring and Managing Longleaf Pine Ecosystems" focuses on providing new and improved methods, techniques and tools that will facilitate the restoration of longleaf pine ecosystems and provide guidance for sustainably managing longleaf pine forests for a broad range of products and services.

- Comparing Reproduction Techniques for Longleaf Pine Forests (2014)
- Methods of even-aged management for longleaf pine are well known, but techniques for uneven-aged management have been poorly understood and largely untested. New approaches to uneven-aged management increase the number of options available to forest managers, so a broader range of resource values and interests can be considered when recovering and sustaining these unique ecosystems.
- Dynamics of longleaf pine cone production in the southeastern U.S. (2017)
- Longleaf pine cone production is the result of complex interactions between trees and their environment. Multiscale entropy reflects the complex flow of information among these many ecosystem parts.
- Is the relationship between tree height and diameter consistent across species and ranges? (2017)
- Scaling exponents reveal differences in longleaf pine height-diameter relationships across its range, possibly due to water availability. Tree species adapted to swampy conditions have developed growth forms that result in deviations from expected relationships.
- New Management Technique Offers Promise for Longleaf Pine Forests and Beyond (2010)
- SRS researchers and partners developed a new technique for managing longleaf pine forests called the Proportional-B (Pro-B) Method. Results show forest personnel can easily learn and apply Pro-B and achieve desired outcomes in the forest.
- Restoration Treatments for the Post-Hurricane Recovery of Longleaf Pine (2012)
- Scientists recommend herbicide use to control hardwoods in plantings of longleaf pine after hurricane damage
- Selection silviculture can be well-suited to longleaf pine forests (2017)
- Uneven-aged silviculture continues to show promise as an effective way to regenerate longleaf pine stands. Uneven-aged silviculture also maintains continuous canopy cover that aids in the control of woody competitors and supports an array of resource values.
