Erosion Control on the LaBarque

LaBarque Creek has changed over the years, and the side nearer the highway, when it was in full flood, eroded way into the clayish soil until there was a 6-foot dropoff at the creek bend. A daydreamer walking in that meadow (formerly a baseball diamond) could have taken a step like Wile E. Coyote and plunged right into the drink. The Divine property is adjacent to newly public land, and the Missouri Department of Conservation came to here to stabilize this creek bank. Concerned about the same erosion, Demetrius and I had tried to plant native trees there some years ago. We had the right idea but wrong approach.

First, the conservation people cleared that meadow of its cedars, which are invasive and non-native trees here, but instead of letting 'em lie, anchored them to the creek bank sidewise and halfway in the water, as you see in the photo. They act like tree roots, capturing natural debris that helps rebuild the creek bank, while serving as habitat for fish and other water creatures. They filled in some of the slope with dirt. And then some volunteers planted, like, a thousand willow trees which will grow quickly and further stabilize the creek bank. You can see the willow slips, just about six inches tall, in the meadow, planted in rows, croplike.

This is green creativity at its best!

Hooray. Nice to know you tried to come up with a solution. Nicer to know the "govenmint" came up with a good one. You go, willows.
