1 Introduction

The South's forests are expansive, diverse, and vital. Many forces-ranging from development to environmental change to timber management-continue to shape them. Although change has been constant, the rate of change is accelerating and has raised questions about the sustainability of southern forests and the broad complement of values they provide.


Sustainability is a sweeping concept-ensuring opportunities for the future as resources are used today. Pursuing sustainability requires broad and long-term commitment and ongoing monitoring, study, and action. The first step is to understand and anticipate the forces of change that will directly shape forested ecosystems and the social factors that are likely to drive those changes. Ultimately, society must manage change to achieve sustainability.


The Southern Forest Resource Assessment documents and analyzes the many factors that are affecting the forests of 13 Southern States (Figure 1.1). Our goal has been to answer several specific questions about southern forests and their uses, and in the process, to create a comprehensive base of information about them. This undertaking is complex given the multiple factors that influence forests, the diversity of the region's people and biota, and the history of land and resource uses.

The South has a strong regional identity that is shaped in large part by its agrarian past and the predominantly private ownership of its land. With more than 5 million private owners controlling


89 percent of southern forests, forest area and conditions are influenced by diverse landowner interests and objectives. An ever-changing patchwork of forest uses and conditions has resulted.


Not surprisingly, interest in these forests extends far beyond landowners to all who use their varied goods and services. As organizers of this Assessment, we have tried to convene these many interests, elucidate and analyze their concerns with science and data, and present findings in a useful way (Figure 1.2). Monitoring change at a broad, multi-State scale and describing cumulative changes is a logical and important role for government in the area of private forestry.

This Assessment was organized around 23 questions that summarized public concerns about southern forests and their uses (Table 1.1). These questions were refined during a process that involved considerable public review in venues ranging from large meetings to one-on-one discussions. More than 750 people participated in the meetings; hundreds more provided written input. Once the questions were finalized, a rapid scientific assessment process was developed and employed to address each using available knowledge and data. Each question was addressed by subject experts who comprised the Assessment Team, and their work is presented as individual chapters in the Assessment's Technical Report. Data used in the Assessment has been assembled and made available through a public Web site. This report synthesizes and provides some interpretation of the detailed information contained in the Technical Report, but does not provide an exhaustive compilation of all of its findings.

The Assessment effort was designed by participating agencies as a two-tiered approach. The Summary Report and the Technical Report represent the first tier, a broad comprehensive assessment of resource questions. The second tier will begin by identifying small areas within the South for additional study at finer scales. Findings from the broad scale assessment will be used to identify areas where forces and implications of change are currently strongly focused or are expected to be strongly focused. The number of subregional assessments sponsored by the Assessment will depend on availability of funding and other resources. Specific questions to be addressed will be determined by the issues faced in each area and will be defined at a later date. In addition, the findings of the Assessment coupled with the identification of small areas may prove useful for focusing the efforts of future researchers.


In the sections that follow, we examine how several forces of change have shaped and may continue to shape the forests of the South. Forces of change include social, biological, and physical forces. We then examine the history, status, and possible future of southern forests in four different dimensions: social and economic systems, forest area and conditions, terrestrial ecosystems, and aquatic ecosystems. We conclude by examining the broad implications of these findings and list major knowledge gaps and scientific uncertainties.


Throughout the sections that follow, the Technical Report is the source of all of our findings. Accordingly, individual sections that follow refer to the specific chapters in the Technical Report from which the findings are drawn, using the naming convention shown in Table 1.1. For example, SOCIO-1 refers to the first chapter in the Social and Economic Systems section, which addresses the question: "How have land uses changed in the South, and how might changes in the future affect the area of forests?" Each section is keyed to the chapters that are primary sources of findings. The individual chapters provide in depth analysis of the issues and extensive citations to primary references on each topic and should be reviewed for more detailed information.
