Restoring and Managing Longleaf Pine Ecosystems (SRS RWU 4158)
To provide knowledge and strategies for restoring, managing, and sustaining longleaf pine ecosystems
Initiated during the realignment of the Southern Research Station in 2007, SRS RWU- 4158 is a team of 6 scientists and support personnel whose mission is to provide knowledge and strategies for restoring, managing, and sustaining longleaf pine ecosystems in the southeastern United States. Scientists in the Unit work on two overarching research problems. They design and carry out research studies that seek to solve these problems or overcome related limitations to our knowledge of longleaf pine ecosystems. The Unit's scientists work with partners to provide knowledge and technologies needed to successfully restore and manage these ecosystems which are increasingly affected by a variety of human and natural influences in times of environmental stress and cultural and climatic change. The problem areas are as follows:
- Providing fundamental physiological knowledge needed to understand the processes that affect longleaf pine seedling production, establishment, and growth and development.
- Providing ecological information about population and community processes that affect restoration of longleaf pine woodlands and at risk native plant species.
- Providing practices, strategies, and models that quantify and predict the influence of management on maintaining and restoring longleaf pine ecosystems.
Our scientists work with partners and cooperators to provide knowledge and technologies needed to successfully restore and manage these ecosystems as they are increasingly affected by a variety of human and natural influences in times of environmental stress and cultural and climatic change.

Longleaf Pine Stand Understory
Longleaf pine trees once rose to the sky on more than 90 million acres across the Southeast, towering over grasses and flowers and providing habitat for many animals that are now rare. Less than 3 million acres of these forests remain, but returning degraded ecosystems to longleaf pine forests is a priority for many managers and organizations.
U.S. Forest Service scientist Joan Walker and her colleagues developed a roadmap for restoring these forests, especially the understory plant communities. Walker, a plant ecologist at the Forest Service Southern Research Station Restoring Longleaf Pine Ecosystems unit, co-authored a study that quantified and evaluated a reference model for use in restoring southeastern U.S. longleaf pine woodland understory plant communities. The study was led by Lars Brudvig, a professor at Michigan State University, and published in an article in PLoS ONE. Read more in the CompassLive article.

Pro-B, a method developed by U.S. Forest Service research, helps make uneven-aged management of longleaf pine and other forest types a practical and efficient option for landowners and managers. A field study by researchers showed that after less than three hours of training on the Pro-B (proportional basal area) method, managers were able to accurately mark stands using only a single marking pass.
Dale Brockway, research ecologist with the Forest Service Southern Research Station (SRS) Longleaf Pine Restoration and Management unit, worked with SRS emeritus scientist Ken Outcalt and Auburn University’s Ed Loewenstein (formerly of the Forest Service Northern Research Station) to create a technique that managers can easily use to apply uneven-aged management in the forest. Pro-B may be used to implement selection silviculture in a variety of forest types in the Southeast, elsewhere in North America, and perhaps on other continents as well.
