  • Recovery Strategy for Northern Riffleshell, Snuffbox, Round Pigtoe, Mudpuppy Mussel and Rayed Bean in Canada
    Recovery Strategy for Five Ontario Freshwater Mussels December 2006 Species at Risk Act Recovery Strategy Series Recovery Strategy for Northern Riffleshell, Snuffbox, Round Pigtoe, Mudpuppy Mussel and Rayed Bean in Canada. December 2006 Recovery Strategy for Five Ontario Freshwater Mussels December 2006 About the Species at Risk Act Recovery Strategy Series What is the Species at Risk Act (SARA)? SARA is the Act developed by the federal government as a key contribution to the common national effort to protect and conserve species at risk in Canada. SARA came into force in 2003 and one of its purposes is “to provide for the recovery of wildlife species that are extirpated, endangered or threatened as a result of human activity.” What is recovery? In the context of species at risk conservation, recovery is the process by which the decline of an endangered, threatened or extirpated species is arrested or reversed, and threats are removed or reduced to improve the likelihood of the species’ persistence in the wild. A species will be considered recovered when its long-term persistence in the wild has been secured. What is a recovery strategy? A recovery strategy is a planning document that identifies what needs to be done to arrest or reverse the decline of a species. It sets goals and objectives and identifies the main areas of activities to be undertaken. Detailed planning is done at the action plan stage. Recovery strategy development is a commitment of all provinces and territories and of three federal agencies — Environment Canada, Parks Canada Agency and Fisheries and Oceans Canada — under the Accord for the Protection of Species at Risk.

  • Ontario Species at Risk Evaluation Report for Round Pigtoe
    Ontario Species at Risk Evaluation Report for Round Pigtoe (Pleurobema sintoxia) Committee on the Status of Species at Risk in Ontario (COSSARO) Assessed by COSSARO as ENDANGERED December 2014 Final Pleurobème écarlate (Pleurobema sintoxia) Le pleurobème écarlate est une moule d’eau douce qui peut atteindre une longueur de 13 cm. L’épaisse coquille des adultes est brun acajou parcourue de lignes foncées. Au Canada, le pleurobème écarlate est présent dans le sud-ouest de l’Ontario, dans le delta de la rivière Sainte-Claire et dans la rivière Sydenham River, et qu’en petites populations dans les rivières Grand et Thames. Il pourrait avoir disparu du lac Érié et de la rivière Niagara, mais il faudra réaliser d’autres relevés pour le confirmer. Le pleurobème écarlate utilise différents habitats, notamment les rivières et les lacs aux eaux profondes et aux fonds sablonneux, rocheux ou boueux. Comme toutes les moules d’eau douce, il se nourrit d’algues et de bactéries qu’il filtre hors de l’eau. Les larves de moules sont des parasites qui s’attachent à un poisson-hôte dont elles puisent les nutriments jusqu’à leur métamorphose en juvéniles, puis s’en détachent. Les hôtes du pleurobème écarlate sont, entre autres, le méné bleu, le ventre rouge du Nord, le ventre-pourri et le crapet arlequin. Le pleurobème écarlate est une espèce en voie de disparition en Ontario. Il est présent dans quelques endroits à peine, et le nombre de sites ne cesse de diminuer depuis 10 ans en raison de la présence des moules zébrées envahissantes (critères A2, B1 et B2 du CDSEPO).

  • Appendix a Heritage Impact Assessment Report
    APPENDIX A HERITAGE IMPACT ASSESSMENT REPORT October 9, 2015 HERITAGE IMPACT ASSESSMENT Holt Line Bridge (Duthill Bridge/10th Concession Bridge) Spanning the Sydenham River, St. Clair Township, Ontario Submitted to: Kelly Vader, MCIP, RPP BM Ross and Associates Limited 62 North Street Goderich, ON N7A 2TA Report Number: 1534665-R01 Distribution: 1 Copy - BM Ross and Associates Limited REPORT 1 Copy - Golder Associates Ltd. HIA - HOLT LINE BRIDGE - TOWNSHIP OF ST. CLAIR Executive Summary Golder Associates Ltd. was retained by B.M. Ross and Associates Ltd. (B.M. Ross) to undertake a Heritage Impact Assessment (HIA) for the proposed rehabilitation or replacement of the of the Duthill Bridge, also known as the Holt Line Bridge, located on Holt Line in the Township of St. Clair, Ontario. The objective of the HIA was to determine whether the structure represented a built heritage resource or a part of a cultural heritage landscape of cultural heritage value or interest. The analysis of the Duthill Bridge was guided by the Ontario Ministry of Tourism, Culture, and Sport’s (MTCS) Ontario Heritage Toolkit: Heritage Resources in the Land Use Planning Process. This HIA makes the following recommendations: Subject to the confirmation of preferred alternatives for the potential rehabilitation or replacement of the Duthill Bridge, St. Clair Township should consider the mitigation options identified in Section 5.3 of this report to evaluate the potential options that would conserve the cultural heritage value of the bridge. From a best practice standpoint for the conservation of heritage resources, the preferred alternative for the Duthill Bridge would be one of the following three options: Construction of a new bridge adjacent to the existing structure: The retention of the bridge in situ as a part of a pedestrian or recreational vehicle crossing would act as a form of mitigation.

Bottom fauna were sampled and water samples were collected for bacteriological, algal and chemical analyses for most of the 43 stations on the watershed. With few exceptions, bottom faunal communities at stations on the east Sydenham were indicative of water of satisfactory quality. Minor qualitative impairment was evident a half-mile below the Strathroy retention ponds while a community typical of an organically enriched situation was recovered at the point where the river transects the tenth concession Brooke Twp.
