Early settlers drained marshy US landscape


environment.newscientist.com

In the US, a multibillion-dollar landscape restoration industry is guided by the almost intuitive notion that natural, gravel-bedded streams wander in single channels across the land.

This springs from the assumption that, when European settlers arrived in the 17th century, they found a picturesque landscape of forested hills and meandering streams that carved their way down the valleys and out to sea.

But a new study now overturns this notion, suggesting that the meandering streams are actually the result of early forms of land management imposed by the settlers.

This new study indicates that the early settlers of the US had a much greater effect on the land than proviously thought. Every valley had a steplike series of mill dams that greatly changed to preexisting marshland. The effect of these mill dams is still being felt in the form of silty rivers after each heavy rain. Previously the silt was assumed to come from poor farming practices but now they realize that at least part of the silt is coming from the breakdown of the old mill dams.

Apparently conservation and landscape restoration programs should be reevaluated as a result of these findings!

Gee, coastal marshes, who’d of thunk it?
I never cease to be amazed by the self-centered short sightedness of ‘scientists’. Great post.
