Description

Despite their importance in wetland systems, few studies have focused on aquatic mollusks in Alberta, and available data is too limited to accurately determine their range, habitat requirements and biological status. This study reports on a detailed inventory of aquatic mollusks in the Central Parkland subregion of central Alberta conducted in 2001. The goal of the survey was to clarify the biological risk of many species that are currently classified as being of Undetermined status in the province. This report deals only with the aquatic gastropods; analysis of bivalves will be reported at a future date.
