He also studies changes in forest plant communities and soil productivity following forest management treatments. He has directed a region-wide study team since 1984 that has been documenting pine plantation development and the influences on plant diversity and soil changes in seven southeastern states. This study has international recognition.
He has published over 100 reports and popular articles: most noteworthy is the book and CD-version entitled Forest Plants of the Southeast and Their Wildlife Uses coauthored with Dr. Karl Miller, noted wildlife professor at the University of Georgia. Over 10,000 copies have been sold by the University of Georgia Press with proceeds going to the graduate student program for the Southern Weed Science Society.
He has designed and initiated a regional monitoring system for tracking invasive plants used by the Forest Service and state partners. Current maps can be viewed at invasive.org/south/. The identification guide used for this survey, Nonnative Invasive Plants of Southern Forests: A Field Guide for Identification and Control, has 140,000 copies distributed in the U.S. An expanded two volume version will soon be available.
Miller's work has been honored by two national U.S. Secretary of Agriculture Awards, besides other State and regional awards.
