Figure 2A depicts the historical distribution of L. fasciola in Ontario (and Canada), based on occur- rence records (for both live animals and shells) from the National Water Research Institute's Lower Great Lakes Unionid Database. The database and its data sources are described in detail in Metcalfe-Smith et al. (1998a). At present, the database consists of over 5000 records for 40 species of mussels collected from the Canadian waters of the lower Great Lakes drainage basin between 1860 and 1998. A total of 22 historical (pre-1997) records for L. fasciola were available from the holdings of the Canadian Museum of Nature (CMN), Ohio State University Museum of Biological Diversity (OSUM), Royal Ontario Museum (ROM) and University of Michigan Museum of Zoology (UMMZ); the private collec- tions of Herbert D. Athearn, Emeritus, Tennessee Academy of Science; Mackie (1996*); and Morris and Di Maio (1998). Protection Canada does not have federal endangered species legislation at this time. However, Ontario is one of five provinces that have stand-alone Endangered Species Acts ( Fowler, Chair, Lepidoptera and Mollusca Subcommittee, COSEWIC, personal com- munication, September 1999). Species classified as provincially Endangered and their habitats are pro- tected from willful destruction under these acts, but ''See Documents Cited section. there is currently no protection for provincially Threatened or Vulnerable species. The Provincial Policy Statement under Section 3 of Ontario's Planning Act prohibits development and site alter- ation in the habitats of provincially Threatened and Endangered Species.
