Accurate, high resolution information does not exist regarding the status and trends of water quality and aquatic biotas throughout the 2,000,000 kilometers of river and stream networks in the U.S. Without this information, prioritization of limited conservation resources within and among resource agencies proceeds inefficiently.Document Type: Briefing Papers

Applications of spatial statistical network models to stream data

Publications Posted on: March 12, 2014
Streams and rivers host a significant portion of Earth's biodiversity and provide important ecosystem services for human populations. Accurate information regarding the status and trends of stream resources is vital for their effective conservation and management. Most statistical techniques applied to data measured on stream networks were developed for terrestrial applications and are not optimized for streams.
