Research Summary

  • Dwyer’s current research emphasis has been in the evaluation and assessment of production from various cottonwood clones collected from the Midwest. Along with this evaluation of physical productivity is the evaluation of cottonwood flood tolerance under various flooding regimes. Dwyer has also been involved in the management of northern red oak and sugar maple grown on Menominee Tribal Lands in Wisconsin. These studies involve determining the relationship between tree characteristics and volume and value of these trees managed over time. Dwyer is also involved in determining the impacts of raising cattle, forage, and thinning on Ozark oak stand dynamics. His other interests include using low-value, small diameter hardwoods in bio-fuel projects to reduce hazardous fuels buildup and also to improve the health and growth of stands suffering from Red Oak Decline and Red Oak Borer infestation. He also has an interest in the identification and evaluation and development of superior black walnut cultivars for timber production.
