Nature Preserves, Wildlife and Environmental Research Wildlife habitats depend on our wetlands and we, in turn, need to respect their needs. EZ Dock sections allow light to penetrate through the docks, fostering plant growth that is essential to wildlife. EZ Dock's designs utilize our patented hollow sections that eliminate the use of foam for floatation. Foam can often be dangerous to wildlife when it deteriorates and breaks apart, leaving toxic pieces in the water. We developed our product to work in harmony with the environment - not against it. EZ Dock does not contain toxins or other ingredients that could harm wildlife like treated wood or foam filled products can.
