“BioHaven® is a commercially available floating wetland”, explains Leela O’Dea, an ecologist and founding partner at the aquatic environmental consulting firm, Frog Environmental. “It is about six inches deep and made up of a recycled plastic matrix, which allows plants to grow on it…The advantage of this system is that the roots offer a really high surface area for microbial and sedimentation processes to take place,” says O’Dea. “There are a lot of microscopic particles or colloids suspended in the water and the dangling roots, which are covered with a sticky biofilm of microbes, help the sedimentation of these colloids.” Once the roots become heavy they drop off and carry the colloid contaminants away into the sediment at the bottom of the water. “The sedimentation process is especially important for the removal of phosphorus,” says O’Dea, “because phosphorous often adsorbs to soil particles and so gets trapped in colloids.”
Natural floating islands, also called sudds, tussocks, floatons, or embalsados, are typically composed of floating vegetation, or peat, or both, along with mud, and may attain substantial thickness and longevity, sustain abundant riparian vegetation, and provide habitat for high densities of fish.
A BioHaven Floating Island ® is a man-made floating wetland. Inspired by the natural occurring floating peat bogs in Northern Wisconsin, BioHavens ® were originally designed to mimic mother nature’s own creation…floating wetlands. Using Nature to cleanse nature is a form of Biomimetics.
Biohaven® floating island technology, has been successfully applied in several conservation contexts throughout the world. These conservation efforts, include enhancing fish habitat through manmade floating wetlands, aiding in restoration efforts of endangered species, and more.
