Recovery Strategy for the Hickorynut and the Kidneyshell [Final Version]

Recovery Goal

The long-term goals of this recovery strategy are:

  1. to prevent the extirpation of the Round Hickorynut and Kidneyshell in Canada;
  2. to return healthy self-sustaining populations of Round Hickorynut to the Sydenham River and Lake St. Clair delta and;
  3. to maintain healthy self-sustaining Kidneyshell populations in the Ausable and Sydenham rivers while returning the Lake St. Clair delta population to a self-sustaining level.
  4. o re-establish populations in historically occupied habitats.

These populations can only be considered recovered when they have returned to historically estimated ranges (see Figure 3 and 6) and/or population densities and are showing signs of reproduction and recruitment.

Recovery Objectives (5 year)

  1. Determine extent, abundance and population demographics of existing populations.
  2. Determine fish hosts and their distributions and abundances.
  3. Define key habitat requirements to identify critical habitat.
  4. Establish a long-term monitoring program for Round Hickorynut and Kidneyshell populations, their hosts and the habitat of both.
  5. Identify threats, evaluate their relative importance and implement remedial actions to minimize their impacts.
  6. Examine the feasibility of relocations, reintroductions and the establishment of managed refuge sites.
  7. Increase awareness about the distribution, threats and recovery of these species.
