Colicroot, Aletris farinosa, in Canada COSEWIC status report on the colicroot, Aletris farinosa, in Canada Ottawa : Environment Canada, Canadian Wildlife Service, COSEWIC Secretariat, c2015. xiii, 39 p. : col. ill., maps (some in col.) Issued also in French under title: Évaluation et rapport de situation du COSEPAC sur l’alétris farineux, Aletris farinosa, au Canada. Cover title. "Endangered, 2015." "COSEWIC would like to acknowledge Judith Jones (Winter Spider Eco-Consulting) for writing the status report [...]. This report was overseen and edited by Bruce Bennett, Co-chair of the COSEWIC Vascular Plants Specialist Subcommittee"--Cf. (p. ii). Includes bibliographical references (p. 31-36). "For this report, more than 46 sites where Colicroot was reported since 1975 were visited to update information. Despite discoveries of new sites, the results show a loss of 22 patches (38% of total patches), a measurable loss of more than 27% of total number of mature individuals, and an inferred loss much greater than that. Based on guideline 3 of the COSEWIC Guidelines on Manipulated Populations, the subpopulations manipulated during the construction of the Parkway are not included in the application of quantitative criteria until it can be demonstrated that the transplants are having a net positive impact on Colicroot. Furthermore, it is unknown whether one subpopulation present in 1992 is extant. If extirpated, the loss of this subpopulation would cause a decline of 47% in the extent of occurrence (EOO). Habitat for Colicroot is extremely limited, and protective management has not prevented losses”--Preface, p. xi. gccst Endangered species gccst Wild plants gccst Nature conservation Jones, Judith.
