- Coggeshall’s current research is focused on temperate agroforestry practices that emphasize both environmental service benefits as well as economic returns derived from the production of specialty crops. For example, identifying the genetic basis for flood tolerance among a range of hard mast producing tree species can provide significant environmental benefits for the establishment of new riparian buffers. In terms of specialty crops, he has developed an applied breeding program for eastern black walnut that is focused on the genetic improvement of a range of commercially important nut production characteristics. Additionally, he has initiated applied research programs in cooperation with the Missouri Department of Conservation that focus on black walnut timber improvement, shortleaf pine restoration, early fruiting in swamp white oak for wildlife enhancement plantings and the use of flood tolerant oak seedlings for establishing new riparian buffer plantings.
