A targeted survey for hickorynut in wadeable habitats along Ottawa River tributaries and the lower Spanish River (Lake Huron) in 2018 / by Anita LeBaron, Matt Sweeting and Scott M. Reid.: Fs97-13/1306E-PDF
"Targeted surveys of the endangered Hickorynut (Obovaria olivaria) were needed to inform the delineation of critical habitat, and the design of future surveys and population assessments. During the summer low-flow period of 2018, timed-search surveys using visual-tactile methods were conducted in wadeable habitats along reaches of the lower Spanish River (Lake Huron) and five Ottawa River tributaries. A total of 4,256 live individuals representing seven species were collected across 14 sites in the Ottawa River drainage, and 684 individuals representing four species were collected at three sites in the Spanish River delta. Eastern Elliptio (Elliptio complanata) was the most widespread and abundant species, accounting for more than 80% of all live individuals. Hickorynut was not detected at any site as shell or live individual. Surveys on the Spanish River were hindered by high water levels; supplementary sites have been identified for potential future surveys using alternate sampling methods to access deeper habitat. Additional survey locations in Ontario may be informed by known distributions of Lake Sturgeon (Ascipenser fulvescens), the obligate host of Hickorynut"--Abstract, page v.
