This is an image of Kenneth Tiffan out in the field. Ken works to conduct applied research to provide information that would increase our understanding of Snake River fall Chinook salmon, listed as “threatened” under the ESA in 1992. His career has focused on this unique stock and facilitating recovery efforts.
