Jeffrey Marion, Ph.D.

Adjunct Professor
  • B.A., Wittenberg University, 1979 
  • M.S., University of Minnesota, 1982 
  • Ph.D., University of Minnesota, 1984

Academic Interests - Recreation ecology:  research and monitoring to evaluate environmental impacts resulting from recreational activity in protected natural areas.  Research to: 1) identify, measure, and manage recreation resource impacts, 2) model and understand the influence of use-related, environmental, and managerial factors, 3) evaluate the efficacy of educational, site management and, regulatory actions designed to avoid or minimize recreation impacts, and 4) support and improve carrying capacity planning and decision-making.
