COSEWIC assessment and status report on the Butternut in Canada

Acknowledgements and Authorities Consulted

The butternut literature review by V.R. Fleugel was used as a starting point in putting together the present report. Dr. Mike Ostry, USDA North Central Forest Experiment Station, Henry Kock, University of Guelph Arboretum, and Dr. Martin Hubbes, professor emeritus, University of Toronto, all participated in discussions at the commencement of our report preparation, and we are indebted to their deep interest and open sharing of ideas and literature. Henry Kock and Rob Guthrie provided Tree Atlas data; the Atlas would not have been possible without the many landowners and volunteers who provided info and compiled the data, and financial support from the Ontario Forest Research Institute. The authors also appreciate the contributions of data and information from a variety of contacts.

Karen Zhou, OMNR Terrestrial Assessment Program database specialist, assisted with assembling growth and yield data. Bob Johnston, OMNR Regional Native Liaison Officer, OMNR Northeast Region, reviewed the aboriginal traditional knowledge section. Sylvia Greifenhagen, Ontario Forest Research Institute, assisted with assembling pathology information. Bob Sajan assisted with assembly of insect pest descriptions. Allen Bibby, Corey Van Es (Kemptville District, OMNR) and Mike Dunkley (Science and Information, Peterborough, MNR) assisted with map preparation. Ed Hurleyand Ken J. Harrison, Natural Resources Canada, Canadian Forest Service provided information on the status of butternut in New Brunswick. The cover image of a butternut silhouette is from Farrar, 1998 (Trees in Canada CD-ROM), and is used with permission.
