Report on the progress of recovery strategy implementation for the Round Hickorynut (Obovaria subrotunda) and the Kidneyshell (Ptychobranchus fasciolaris) in Canada for the period 2006–2011

As a result of the overlap in the historic and current ranges of the Round Hickorynut and
Kidneyshell, there is substantial commonality in threats to their continued survival. A key
component in the progress towards fulfilling recovery objectives has been the systematic
collaboration with existing ecosystem recovery teams. This collaboration has taken the form of
multiple research projects as well as stewardship teams that actively monitor and coordinate
habitat improvement projects on the Ausable, Sydenham, and Thames rivers systems. These
collaborative efforts resulted in concrete progress in the form of habitat improvement and
protection, and important biological insights of these two species.
