Use an HDSS survey to increase collaboration, participation, information exchange, and learning while reducing the cost of data collection. HDSS supports an Integrated Planning Framework by providing the organizations involved with data necessary to address their unique concerns. A single survey can be used to address the needs of various organizations working collectively in and along the stream corridor.

With data collected from a single field survey, organizations involved are more informed, innovative, and efficient allowing for better science. This allows the organizations to focus on high-quality outcomes and the more difficult problems. Additionally, when the needs of multiple organizations are understood and met more resources are made available to implement additional actions and/or more expensive solutions.
