Acknowledgements and Authorities Contacted

This updated status report is based upon previous COSEWIC status reports for Soapweed, prepared by Fairbarns (1985) and Csotonyi and Hurlburt (2000).

The provision of data and observations by Bruce Milner, Joel Nicholson, Cathy Linowski, Ian Walker, Dan Johnson, Buck Cunninham, Peter Harris and Kathryn Romanchuk for the preparation of this report was greatly appreciated. Logistic support for field verification was kindly provided by Paul Gregoire (SARA Permit Coordinator, Canadian Wildlife Service), Erl Svendsen (Supervisor, AAFC - Saskatoon), Dean Hystad (Rangeland Agrologist, Alberta Sustainable Resource Development), Joel Nicholson (Senior Species at Risk Biologist, Alberta Fish and Wildlife), Ian Walker (Manager, Onefour Research Substation), Doug Mullin (Integrated Services Manager, AAFC - Lethbridge), and Laura Lee Chomicki (Material Management, AAFC - Lethbridge). Particular thanks are extended to Doug Mullin and Laura Lee Chomicki for expediting the process to gain access to Onefour.

The report writer particularly wishes to acknowledge the contributions and dedication of the late Dr. Johan Dormaar to the conservation of Soapweed and yucca moths in Alberta. Johan was instrumental in providing a historical knowledge of the habitat and the species in Alberta and on an almost annual basis hiked the Milk River coulee looking for an unconfirmed population of Soapweed plants. The report writer greatly misses his enthusiastic reports on Soapweed flowering and fruiting that he so willingly provided after she returned to Nova Scotia.

Preparation of this report was funded by the Canadian Wildlife Service, Environment Canada.
