The California Fish Passage Forum is developing a fish passage barrier optimization tool, a decision support tool for optimizing barrier mitigation for anadromous fish. The tool assists in identifying cost-efficient mitigation actions to maximize the amount of accessible habitat above barriers, using a mixed integer linear programming formulation. The tool integrates information on barrier passability, potential habitat, and mitigation cost and accounts for spatial structure of barrier networks as well as interactive effects of mitigation decision on longitudinal connectivity.
The Forum will begin testing the tool in the spring of 2015. In the interim, the Forum is gathering existing fish passage barrier lists in California as well as describing the comprehensive suite of recovery plans currently informing restoration efforts.
