Gun River Tree Revetment Site
The Watershed Project has provided technical assistance and installation guidelines to install a 140 foot tree-revetment project on the Gun River. This project used conifer trees anchored into the “toe” of the stream to prevent erosion from occuring and to rebuild the river bank.
Tree revetments greatly slow the current along the eroding bank; this decreases erosion and allows silt and sand to be deposited along the bank and within the tree branches. The deposited material forms a good seed bed in which the seeds of river trees such as cottonwood and sycamore can sprout and grow. The resulting trees spread roots throughout the revetment and streambank. By the time the revetment trees have decayed, the bank should be stabilized by the roots of the living trees. As an added benefit, tree revetments provide excellent fish and wildlife cover.
