Due to the location and ecological characteristics of our focus areas, EBC has a variety of rare species on our nature reserves. These species include those that are considered rare provincially and at-risk in Ontario and Canada. The designations used in the table below represent these different levels. EBC protects habitat of approximately 50 rare species.

The S-Rank (Sub-national Rank) indicates a species “rarity” within a particular province/territory/state. An S-Rank is assigned by the OMNRF’s Natural Heritage Information Centre using the best available knowledge. Low S values indicate rare/at risk species, those ranked S3 are considered vulnerable, S2 are considered to be imperiled and S1 are critically imperiled. Those that show a combination of S values indicates a range rank to indicate uncertainty.

The SARO column indicates “Species at Risk in Ontario”, or, those listed under the Ontario Endangered Species Act, 2007. These designations include Special Concern, Threatened, Endangered, and Extirpated species. This list is developed and reviewed by a group of experts referred to as the Committee on the Status of Species at Risk in Ontario (COSSARO) and approved by the Ontario government. For more information, please visit the Ontario Species at Risk website.

The COSEWIC column indicates the designated assigned by the “Committee on the Status of Endangered Wildlife in Canada”. Similar to COSSARO, this committee is an independent body of experts that review and advises the federal government on species designations. Once COSEWIC provides a recommendation to the federal government, the government must then conduct their own review of the species before a federal status is assigned. The COSEWIC designation is important, because they meet and assess the status of wildlife twice per year. This means that the status of species are up-to-date and revise the status as necessary with the information available. For example, the Monarch was changed from Special Concern to Endangered in November 2016 by the COSEWIC, it is still listed as Special Concern in both Ontario and Canada.

The SARA column indicates the current designation under the Canadian Species at Risk Act, 2002. Once a species is reviewed by the government and a designation is given, there are several other actions that follow. This includes the development of recovery strategies, action plans and management plans. Once a species is designated under Schedule 1 of the Species at Risk Act, there are several laws in place that help protect them. Find out more information about the Species at Risk Act!

The following table was developed in March 2017 using the most up-to-date information available for species at risk designations and S-Ranks from NHIC and the websites for COSEWIC, SARO and SARA provided above. Information will be updated as required.
