This thesis is an investigation of how to restore amphibian habitat formerly abundant in our region. Amphibians are fragile animals whose rate of extinction is compounded by traditional urban design. Dependent on two adjacent ecosystems, wetlands and woodlands, an urban amphibian population indicates natural processes are functioning correctly within the cultural fabric. The benefits are global, wetlands help regulate world atmospheric chemistry. The benefits are local, the community has exposure to local evolutionary history, and a threatened kingdom of animals is restored. In order to prove that it is both possible and practical to restore amphibian population in urban Puget Sound, this study reviews ecological restoration in the urban context and focuses on amphibian species survival which then becomes the foundation for a design and process proposal. This proposal is applied to a theoretical case study and an actual amphibian restoration project to see how reality differs from theory.
