Hickorynut and kidneyshell (Ptychobranchus fasciolaris) final recovery strategy: chapter 8
Recovery Goal
The long-term goals of this recovery strategy are:
- to prevent the extirpation of the Round Hickorynut and Kidneyshell in Canada;
- to return healthy self-sustaining populations of Round Hickorynut to the Sydenham River and Lake St. Clair delta and;
- 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.
- 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)
- Determine extent, abundance and population demographics of existing populations.
- Determine fish hosts and their distributions and abundances.
- Define key habitat requirements to identify critical habitat.
- Establish a long-term monitoring program for Round Hickorynut and Kidneyshell populations, their hosts and the habitat of both.
- Identify threats, evaluate their relative importance and implement remedial actions to minimize their impacts.
- Examine the feasibility of relocations, reintroductions and the establishment of managed refuge sites.
- Increase awareness about the distribution, threats and recovery of these species.
