Protecting vulnerable waters

Check out this recent paper outlining a vision for protecting the least-protected, most-imperiled surfaces waters. It was led by Irena Creed from Western Univ in Ontario, with contributions from a large working group, including us.

Valuation of ecosystem services provided by vulnerable headwater streams and wetlands outside of floodplains in the contiguous U.S.

In the U.S., the Clean Water Act protects interstate “Waters of the USA”. Protecting such waters requires stewardship and conservation of small, upland aquatic systems like wetland basins and headwater streams, whose ecological functions (e.g., flood pulse dampening, pollutant retention, biodiversity reservoir) determine the condition of downgradient Waters of the USA. Yet, conserving upland waters is controversial because preserving them can inhibit land development. Into this fray, the U.S. Supreme Court waded with two landmark cases limiting the Act’s application, and the current administration drags their feet administering the Act. This paper describes the scientific basis for how small & vulnerable waterbodies high in watersheds are linked (biologically and geophysically) to the rivers draining those watersheds, and it provides scientifically grounded options for protecting these vulnerable waters as governments struggle to find solutions for stewarding waters that serve as hotspots of ecological function.
