Round-leaved greenbrier (Smilax rotundifolia) COSEWIC assessment and status report: chapter 10
Existing Protection or Other Status Designations
Present Legal or Other National Status: COSEWIC, Threatened 2001 (Great Lakes Plains Population).
Present Legal or Other Provincial Status: Ontario MNR Threatened (OMNR 2006). In Nova Scotia, round-leaved greenbrier appears to be secure. The Atlantic Canada Conservation Data Centre ranks round-leaved greenbrier as S4 (Blaney pers. comm. 2006), and the species is considered Green (or “secure”) under the Nova Scotia General Status of Wild Species (Elderkin pers. comm. 2006).
In Ontario the habitat of this threatened species is subject to the habitat protection provisions of the Provincial Policy Statement (PPS) under the Planning Act when development applications are considered. The PPS prohibits development and site alteration in the significant habitat of T and E species. Round-leaved Greenbrier is also listed as a threatened species on Schedule 4 of Ontario’s Endangered Species Act, 2007, and consequently the species will be legally protected when the Act comes into force on June 30, 2008. A specific habitat protection regulation will need to be developed to provide legal protection for the habitat (Information provided by OMNR reviewers, Sept. 2007).
