A cluster of gullies above a newly-graded bank north of Couches Creek, brush treated. Erosion Control, Couches Creek, May, 1935Great Smoky Mountains National ParkA cluster of gullies above a newly-graded bank north of Couches Creek, brush treated. The beginning of erosion on the new bank can be seen below the mouth of lowest gully. Hardwood and pine reproduction is gradually creeping into the old field and, if erosion can be arrested for a few years, a good natural cover will become established. Pines are coming in faster than the hardwoods, but they are not a good erosion control cover because the mat of pine needles soon kills all the grass and herbaceous cover, and it takes years for the fallen needles to become thick enough to check run-off. If planting is necessary, hardwood species should be used. Poles were laid along the contours above the gullies and staked down to check the run-off before it hit the treated gullies.
