Dr. Yeiser established his first research project in forest vegetation management in 1984. He has established one or more new projects each year since. His projects include, but are not limited to, (1) the herbicidal preparation of sites for planting with crop trees (either hardwood or pine), (2) the herbicidal release of seedlings (pine and hardwood) from herbaceous competitors, and (3) the herbicidal release of food crops for wildlife. He has significant research experience with loblolly pine in the Coastal Plain of Arkansas and Texas, slash pine in the Lower Coastal Plain of SW Louisiana, and longleaf pine in East Texas. He has field tested all of the forestry herbicides commonly in use today, including the following active ingredients: glyphosate, imazapyr, metsulfuron, triclopyr, sulfometuron, picloram, and hexazinone. His field research has contributed to the development of labels for all the products commonly used in forestry today. As a result of his research experience, he is commonly an invited speaker for workshops in vegetation management sponsored by the University of Georgia, Clemson University, and Mississippi State University. Furthermore, he also hosts a vegetation management research workshop on odd years and on even years, a workshop on forest vegetation management and forest herbicides for beginners.

Research

1. Loblolly Pine Growth Response To Midrotation Fertilization And Yaupon Control: Objectives are to monitor resource reallocation and resultant growth of midrotation loblolly pine when fertilized with and without yaupon competition.

2. Screening of Woody and Herbaceous Plant Herbicides: Objectives are to screen various existing and new chemicals for potential use in forest tree systems.
