FNR 2020 Year in Review: The Research
FNR Research Breakthroughs
Dr. Rod Williams and his hellbender lab team were instrumental in the success of Mesker Park Zoo in getting captive hellbenders to breed naturally.The state of Indiana also selected the Eastern Hellbender project to highlight as part of the Association of Fish and Wildlife Agencies (AFWA) national effort.
Dr. Mike Saunders and researchers with the U.S. Forest Service looked at the impacts of prescribed fire on quality and economic value of lumber in a treated area.
Dr. Songlin Fei analyzed 16 years of U.S. Forest Service forestry inventory analysis regarding the impact of the emerald ash borer on the destruction of ash forests and concluded that in impacted areas, young trees are dying before they can reach their reproductive stages.
Dr. Guofan Shao’s work on map accuracy was recognized and affirmed by colleagues in “Overselling overall map accuracy misinforms about research reliability.”
Dr. Shao co-supervised a research team composed of several electrical and computer engineering (ECE) undergraduates, who have accomplished real-time measurements of tree attributes, including diameter at breast height (DBH) computation and lowest branch detection. The team successfully demonstrated the capability to automatically measure 1,000 trees in Martell Forest within 36 minutes by driving through a red oak plantation. The driving speed can be doubled or tripled when measuring a walnut plantation with clear ground conditions.
Major Grants
Dr. Tomas Hook and his research team will be providing a checkup on the Coreyon Reef Project in Saginaw Bay in Lake Huron through a new grant from the Michigan Department of Natural Resources and the Environmental Protection Agency.Dr. Jacob Hosen is part of a team that will be studying how hydrology and plant community diversity can be modulated to maximize nutrient retention and minimize the production of greenhouse gasses from wetlands, after receiving a $500,000 grant from the USDA’s National Institute of Food and Agriculture (NIFA).
