The purpose of this paper is to evaluate and discuss the evolution of forest management practices in the United States. The paper discusses the trends in forest management that have occurred within the United States in general, and specifically within the western (Oregon) and southern (North Carolina and Florida) United States. The trends discussed include the three (3) to four (4) epochs of management and use that are generally accepted within the forest management literature, with the exception of North Carolina that is in the process of a fifth (5). The comparative analysis within the paper discusses the western model of management which tends to be distinctly different from the southern model in terms of regulatory approaches. The western model (i.e. Oregon) tends to be highly regulated, while the southern model is primarily voluntary, and quasi-regulatory in terms of using alternative mechanisms of regulation (i.e. Best Management Practices that regulate water quality). The paper also discusses the role of professionalism within the various forest services in each state, although the regulatory mechanism is the most important explanatory variable. In general, each state's forest services tend to be highly professional with licensing requirements, educational services and cooperative management. The two models are also distinctly different in terms of ownership, with Oregon being owned (nearly 50%) by the public, whereas the southern states are dominated by Nonindustrial Private Forest Owners (NIPF).
