Rivers are a vital part of Iowa's ecosystem.
“Rivers in Iowa are the most important corridors of habitat, the ribbons of habitat, that we have left," says wildlife biologist Jim Pease.
Over the past four summers Pease has paddled 1800 miles of Iowa rivers. On these trips he’s learned a lot about habitat, water quality, and human impact on the water ways.
