Efforts to conserve stream and river biota could benefit from tools that allow managers to evaluate landscape-scale changes in species distributions in response to water management decisions. We present a framework and methods for integrating hydrology, geographic context and metapopulation processes to simulate effects of changes in streamflow on fish occupancy dynamics across a landscape of interconnected stream segments. We illustrate this approach using a 482 km2 catchment in the southeastern US supporting 50 or more stream fish species. A spatially distributed, deterministic and physically based hydrologic model is used to simulate daily streamflow for sub-basins composing the catchment. We use geographic data...

This map shows water features where aquatic biodiversity is likely to be important. It shows buffered streams, wetlands, and deepwater habitats that fall within protected areas or TNC portfolio areas. It also shows areas identified as having good biological integrity by the National Aquatic Monitoring Center.
