Orthorectified historical aerial photography for the Petaluma River watershed was developed as a historical reference tool. The historical aerial photography mosaic was used to develop a reconstruction of the historical landscape and prevailing conditions of over approximately 150 square mile Petaluma River watershed. This dataset was developed to provide information for watershed management, the restoration of habitats, flood protection, and local education and research.
This project reconstructs the historical hydrology and ecology of the Petaluma River watershed prior to major Euro-American modification. It demonstrates the efficacy of historical hydrology and ecology in identifying and prioritizing multi-benefit restoration opportunities.
