Covington spent his youth in Oklahoma and West Texas. His father, who died when Covington was young, instilled in his son a love and respect of nature. They spent every other weekend out of doors, living off the land. He also introduced his son to the teachings of restoration pioneer Aldo Leopold, who became a major influence on Covington. Covington's mother was a schoolteacher, and encouraged his scholastic nature. Covington excelled at school, and received his B.A. in Biology at the University of North Texas in 1969. He enrolled directly in medical school, with the intention of studying pediatric oncology. The emotional nature of the work took its toll, however, and he left to teach school in Gallup, New Mexico. Shortly after, inspired by ecology classes taken as an undergraduate, he enrolled in the graduate program at the University of New Mexico, where he earned a M.S. in ecology in 1972. Covington continued on to earn a M.Ph. in 1974 and Ph.D. in 1976 from Yale University's Forestry Department, where Leopold studied. Covington joined the faculty at Northern Arizona University in 1975, and began researching the Ponderosa pine forests in the area. In 1996 Covington became the director of the new Ecological Restoration Program at NAU, which operated within the university's School of Forestry. Researchers from the program began to work with land managers to design, implement, and monitor restoration treatments at a variety of sites in the Southwest, the largest of them at Mount Trumbull in far northern Arizona. In 2000 the program evolved into the Ecological Restoration Institute (ERI), with a focus on research, outreach, and education. The ERI provides work experience, formal course work, and thesis opportunities for undergraduates at NAU. Covington has been recognized as Outstanding Teaching Scholar by NAU for his dedication to involving undergraduates in his applied research projects, and bringing research results into the classroom and the field. Covington also presents invited testimony before congressional and state natural resource committees, gives presentations, and provides field trips for leaders of conservation agencies, such as the Forest Service, the Bureau of Land Management, the National Park Service, and Washington Offices of agencies, such as the Secretary of the Interior, and the Secretary of Agriculture. |

William Wallace Covington (1947, Oklahoma) is a Regent's Professor of Forestry at Northern Arizona University (NAU), and the Director of the Ecological Restoration Institute at NAU. Covington is known for his theories on forest health and restoration, drawn from thirty years of research on the Ponderosa pine forests that surround Flagstaff, Arizona. He has been called perhaps the nation's most visible - and controversial - forest scientist, by Science magazine.[1].

They spent every other weekend out of doors, living off the land. He also introduced his son to the teachings of restoration pioneer Aldo Leopold, who became a major influence on Covington.

Work
Covington has made important contributions to the field of forest ecology in his theories of evidence based conservation, adaptive environmental assessment, ecological restoration, and use of presettlement conditions. He has introduced important theories in Ponderosa pine forest management, including a return to presettlement conditions in order to combat major fires, protect wildlife and endangered species, and increase forest health. [2] His early work at Yale University on organic matter in forest soils and carbon levels led to a theory known as "Covington's curve," which suggested that logged soils lost 50% of their organic matter, and hence their ecologically important loads of carbon, within 20 years. Though the applicability of the theory has been questioned, it continues to have influence in the field.[3] For the last three decades Covington has worked tirelessly to reclaim the glory of the declining Ponderosa pine forests. His goal is to return forest structure and the density of trees to conditions approximately those of natural forests before they were disturbed by the impacts of Euro-American settlers. Research on these "presettlement conditions" led to a series of 1994 papers that present the case that many presettlement Ponderosa stands were swept regularly by cooler, low-intensity fires, making them far less dense than today's forests. In Covington's presettlement model of restoration includes establishing reference conditions, removing younger trees and accumulated ground litter, and application of controlled low-intensity fires in an attempt to reduce competition and produce forests with larger, healthier trees less prone to disease and catastrophic fires.
