A large number of individuals (listed in Ambrose & Aboud, 1986) enthusiastically provided information on locations of individual trees or populations during the original surveys in the late 1970s and early 1980s. Forestry staff in Ministry of Natural Resources (MNR) district offices shared information on known sites from their forest surveys. MNR also provided support funding for the original field surveys and staff time for the recovery planning process. World Wildlife Fund Canada provided funding for the earlier conservation biology study of this and other Carolinian species, as well as supporting the current recovery plan exercise, through the Endangered Species Recovery Fund, jointly with the Government of Canada’s Millennium Partnership Fund. Dr. Colin McKeen provided his phytopathology skills in early assessment of and experimentation with naturally occurring hypovirulent strains of the blight fungus. Dr. Greg Boland advised graduate students to further our understanding of the dynamics of this disease and co-chaired the recovery team. Other members of the recovery team provided their expertise: Dr. Brian Husband, Ken Elliott, Gerry Waldron, and Melody Melzer. A large number of advisors provided input to the plan. The 2001‑02 inventory was supervised by Drs. Husband and Boland; the summarized data and its analysis in the appendix were provided by the former. The fieldwork was organized by John McGrath and assisted by Jeff Tindall and Karen McKendry. The members of the Canadian Chestnut Council stand ready to assist and participate in recovery activities and studies. Andy Graham of the Ontario Soil and Crop Improvement Association reviewed the recovery plan and is ready to cooperate through his network of farm woodlot owners with chestnuts. Funding for the preparation of this status report provided by the Canadian Wildlife Service, Environment Canada.
For the original status report all the MNR district offices within the range of this species were contacted and local records were obtained. More recent records were obtained from the Natural Heritage Information Centre as well as from individuals and the Canadian Chestnut Council.
