Global Protection: Many (13-40) occurrences appropriately protected and managed
Comments: In Canada, land ownership along the reaches of the Sydenham, Thames, Ausable, Maitland, Grand and Saugeen Rivers is mainly private and in agricultural use. Only two small properties in the Sydenham River watershed (7 ha Shetland Conservation Area and 20 ha Mosa Township Forest) ar epublicly owned and somewhat protected. There are 21 natural areas (6200 ha) in the Thames River watershed and most of these are in upper reaches where the mussel occurs. Four indian Reserves occupy 6700 ha of land along 45 km of the river downstream of London but the species has not been found there. Less than 0.5% of land in the Maitland River watershed is owned by the Ausable Bayfield Conservation Authority and Maitland Valley Conservation Authority (total 3580 ha). Less than 3% of th eGrant River watershed is publicly owned and there are 11 conservation areas (one with the species). The Trent River is part of the Trent-Severn Waterway, one of seven national historic canals that are managed and protected by Parks Canada. Occupied habitats in Canadian portions of Lake St. Clair delta fall within the territory of the Walpole Island First Nation but the mussel is more common in the poorer protected U.S. portion of the delta (COSEWIC, 2006).
