Ojibway's Species at Risk
This list contains over 160 species of provincially rare plants and animals recorded from the Ojibway Prairie Complex and neighbouring areas of the City of Windsor and town of LaSalle. No other site in Ontario supports such a concentration of rare species. Plants designated endangered, threatened or extirpated in Canada are noted in the list. Phlox pilosa and Platanthera ciliaris that
are known from old literature reports without the support of specimens are excluded from this list. Eleven species have not been recorded in the past 25 years. Several insect species and ten plant species found at Ojibway (such as the Slender Bush-clover, Lespedeza virginica, shown in the photograph) are not known from elsewhere in Ontario or Canada.
Provincial status is derived from the Natural Heritage Information Centre: Rare Vascular Plants of Ontario (Srank of S1, S2 or S3).
