Species of Conservation Concern Project
Credit Valley Conservation (CVC) is in the process of collecting data on the abundance and geographic distribution of the flora and fauna in the Credit River Watershed. The purpose of this project is to determine population trends and identify species that are at risk of decline. The identification of species of conservation concern will support CVC and its municipal partners in the implementation of policies intended to protect species at risk, significant wildlife habitat, and the biodiversity and ecological integrity of the Credit River Watershed.
Based on a framework of existing policy, local lists (e.g. Distribution and Status of the Vascular Plants of the Greater Toronto Area, draft, Varga et al 2000; The Vascular Plant Flora of the Region of Peel and the Credit River Watershed, Kaiser 2001) population trends and professional judgment, species identified within the Credit River Watershed have been separated into 5 tiers:
|1||Species of Conservation Concern||Federal/provincial legislation, COSEWIC and COSSARO designations, NHIC S1-S3 ranks, local rarity (anticipated)*||Yes|
|2||Species of Interest||Local lists, CVC data, professional judgment||Yes|
|3||Species of Urban Interest||Mississauga NAS Ranks, CVC data, professional judgment||Yes, in urban areas|
|4||Secure Species||CVC data, professional judgment||No|
|5||Non-Native and Non-Native Hybrid Species||Not native to Ontario and/or the Credit River watershed but found planted or naturalized.||No|
* An anticipated outcome is for locally rare species to be updated to Tier 1 status and for CVC to develop policy to protect these species.
CVC will be coordinating an external Conservation Advisory Committee to review trends, determine species status and provide endorsement to the Species of Conservation Concern project as a panel of experts. The intent is for the Species of Conservation Concern list to be scientifically defensible and not solely based on the professional judgment of CVC staff. Once sufficient data has been gathered and tier determinations have been approved by the Conservation Advisory Committee, lists will be circulated to CVC Board of Directors for review. The anticipated outcome is for locally rare species to be updated to Tier 1 status and for CVC to develop policy to protect these species.
CVC asks those consultants and other professionals making observations within the Credit River Watershed to help with our data collection by mapping and reporting Tier 1 and 2 species, and Tier 3 species in urban areas (“tracked species”). The data collected will be critical in the development of guidelines for natural heritage protection and management and will be a valuable tool for planning purposes.
The draft species lists for the Credit River Watershed are available to download from the bottom of this page. They have not been circulated externally and are therefore subject to review. Note that these lists are not intended to replace existing documents or lists at this early stage, but moreover they should complement existing documents/lists.
Information about species at risk can be found on our Plants and Animals of the Credit main page. Please contact the Natural Heritage Department at CVC for more information about submitting your records.
