Our mission: To provide knowledge, strategies, and tools for restoring, managing, and sustaining longleaf pine ecosystems in the United States, and to foster insight about ecosystem restoration globally.
Initiated during the realignment of the Southern Research Station in 2007, RWU-4158 is a team of 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.

News & Events
In the early 1800s, longleaf pine-dominated forests stretched from eastern Texas to southern Virginia and south into central Florida. These forests covered about 90 million acres — nearly the size of the state of Montana.
Today, what once covered 90 million acres is less than 5 million acres, which would easily fit into New Jersey.
