Abstract
Implementation of irrigation system improvements such as canal lining or replacement with pipelines frequently results in the incidental loss of wetland habitat previously supported by seepage or spills from the inefficient system. Although the affected wetlands are typically non-jurisdictional in nature, the salinity control program authorizing legislation requires the replacement of lost wildlife habitat value. This paper discusses various strategies and approaches to address this issue, with particular emphasis on low cost, cooperative resolution. Examples of successful project implementation are provided, together with discussion of the potential ramifications of various long-term management approaches.
