Pioneer Forest - A Half Century of Sustainable Uneven-aged Forest Management in the Missouri Ozarks

Guldin, James M.; Iffrig, Greg F.; Flader, Susan L. 2008. General Technical Report, SRS?108. Asheville, NC: U.S. Department of Agriculture, Forest Service, Southern Research Station. 123 p.

This is a collection of papers which analyze Pioneer Forest, a privately owned 140,000-acre working forest in the Missouri Ozarks, on which the science and art of forest management has been practiced for more than 50 years. The papers discuss how this half century of management has contributed to forest restoration and sustainability on the forest itself and, through its example undergirded by a remarkable body of research, throughout the Ozark region and beyond.

Pioneer Forest: A Case Study in Sustainable Forest Management

Detailed overview of the Design and Description of Single-Tree Selection Forest Management as Used on Pioneer Forest. Data for the period 1957-1997 are presented showing volume measurements for seven major species groups and basal area by diameter class from 6 inches to 24 inches or greater. Economic advantages of this system of forest management are demonstrated by looking at market price increases from Pioneer Forest for the period 1950-1999. Using this information an economic model is applied to an average acre of Ozark forestland managed for the most recent 24-year period (1975-99) using clearcutting versus single-tree selection harvest. From the two management scenarios, including management costs for conducting each sale, the authors showed a nearly doubled rate of return by using single-tree selection harvests.

Missouri's Pioneer in Sustainable Forestry

S.L. Flader. 2004. Forest History Today. Spring/Fall: 2-15.

Susan Flader interviewed Leo and his staff as well as reviewed historical files and Leo's own collection of personal papers at the Western Historical Manuscripts Collection housed on the University of Missouri-Saint Louis campus. Here she shares a wealth of information as well as historical photographs from the Pioneer Forest archives. Flader chronicles Pioneer's long history beginning in the 1950s. She reviews the adopted method of management known as single-tree selection harvesting and the disfavor it received beginning in the 1960's as even-aged management became the focus of state and federal land management efforts. Flader also presents the more recent history and the recognition that has come to Pioneer Forest by way of a host of research projects, all pointing favorably toward the management and its effects on the forest and its biota.
