The trails at Se7en Wetlands are on "berms". A berm is a raised strip of land that serves as a path or protective wall. At Se7en Wetlands, the berms serve as both. Our berms maintain the structure of our wetlands, serving as the "bathtub walls" of each of the wetlands and keeping the water on the intended route throughout the site. The berms also serve as the trails and access roads throughout the site. Because our berms maintain the control of water throughout the site, we are unable to have any structures or vegetation that might compromise the structural integrity of the berm. Therefore, we are unable to allow trees to grow on top of the berms where the trails are. If a tree were to fall in this area, the root ball/base of the tree could impact the stability of the berm.
