COSEWIC assessment and status report on the Bog Bird’s-foot Trefoil in Canada


Thanks to Jenifer Penny who helped with field surveys. George Douglas helped unravel the taxonomy of genus Lotus and also assisted with field inventory. Hans Roemer kindly provided information regarding suitable habitats and Shannon Berch identified the contents of root nodules. The valuable suggestions of Don Eastman improved an earlier draft of the manuscript. Charles Thurkill and Don Piggott were generous sources of local information and showed me around Harewood Plains and Woodley Range. I am grateful to Matt Fairbarns for his strong support in all phases of this study. 

Funding for the preparation of this status report was provided by British Columbia Conservation Data Centre.
