River management is inherently complex, demanding mastery of constantly dynamic conditions even when the climate is stable. As the climate changes, however, river management will become even more difficult and unpredictable—and old models and techniques are likely to fail more often.
Now, researchers from around the world are calling for attention and change to how we manage and model the rivers of the world. Dr. Jonathan Tonkin , a Rutherford Discovery Fellow at New Zealand's University of Canterbury , spoke to EM about why he is arguing that current tools for river management are no longer enough as even historical baseline river ecosystem conditions themselves are changing.
This summer a new way to learn about water recreation—and environmental stewardship—paddled into Ohio. With the help of the Toledo Metropolitan Area Council of Governments (TMACOG) , the US Environmental Protection Agency's (US EPA's) Urban Waters Program brought the Wilderness Inquiry Canoemobile “floating classroom” to Toledo for a few days.
TMACOG Water Quality Planner Sara Guiher spoke to EM about the programming and the experience.
“In August of 2018 we spoke with a representative from US EPA Urban Waters,” explains Guiher. “We received funding through them to bring programming to the area focused on urban water resources. The person that we talked to from US EPA suggested Canoemobile, which we had never heard of.Read More
The North Carolina Wildlife Resources Commission ’s Inland Fisheries Division has been working to restore brook trout in the state. Coldwater research coordinator Jacob Rash, who works with the brook trout team technicians on this project, spoke to EM about the work.
“In North Carolina, brook trout are our only native trout species,” explains Mr. Rash. “With that come biological and ecological considerations as well as cultural importance. A lot of folks here grew up fishing for brook trout with their relatives, so it's an important species that we work to try to conserve. We've done quite a bit of work to figure out where those brook trout populations are and what they are, in terms of genetics.Read More
