Production note

COSEWIC would like to acknowledge Matt Fairbarns for writing the update status report on the dwarf woolly-heads Psilocarphus brevissimus in Canada, prepared under contract with Environment Canada, overseen and edited by Erich Haber, Co-chair (Vascular Plants), COSEWIC Plants and Lichens Species Specialist Subcommittee.

Dwarf woolly-heads Psilocarphus brevissimus was first assessed by COSEWIC as Endangered in Canada in 2003. However, because the original status report failed to note the presence of the Prairie population, which is present at numerous sites in southeastern Alberta and southwestern Saskatchewan, COSEWIC requested that a new update report be prepared for re-evaluation of the species' conservation status.
