Management Tools for Landscape-Scale Restoration of Ecological Functions
The Delta Landscapes Project seeks to develop a set of tools for facilitating landscape-scale restoration of the Sacramento-San Joaquin Delta ecosystem. The project will use the historical perspective of the Delta as a basis to identify landscape scale patterns and characteristics that provided ecological functions (based on the Sacramento-San Joaquin Delta Historical Ecology Investigation). The historical perspective will be compared to the present-day Delta to identify opportunities to restore ecological functions, not by replicating the historical Delta, but by recreating viable habitat mosaics with the vision of how they connect at the landscape scale. Conceptual models will be developed to help practitioners identify these landscape level opportunities along with assisting with the development of appropriate metrics to assess individual projects.
The project has four major components:
- Analyzing historical and contemporary Delta landscape spatial habitat patterns
- Comparing past and present ecological function within the Delta
- Developing landscape-scale conceptual models, restoration principles, and target metrics
- Visualizations and public participation
Final products will include an interactive website with landscape visualizations, technical memos, and peer-reviewed publication.
