PROTECTED RIVERS EXPLORER

Conservation Science Partners has partnered with American Rivers to conduct the National Protected Rivers Assessment and develop the Protected Rivers Explorer, a publicly accessible interactive tool providing a nationwide inventory of present-day river protection status along with a series of indicators capturing the main values and threats to our nation’s rivers.

This web-based tool allows river conservation practitioners and policymakers to understand the current state of river protection, celebrate the successes of past protection efforts and identify opportunities to invest in new and secure existing protections in the years to come.
