ABSTRACT:
An ecological system and method for counteracting the effects of excessive nutrient deposition (eutrophication) in bodies of water such as marshlands, inland ponds and lakes. The system makes use of clusters of substantially individualized bark fibers positioned in upper, relatively oxygen-rich zones of such bodies of water. The bark clusters function to attract and hold excessive nutrient deposition in the form of colloidal wastes (e.g., colloidal solids of various types, single cell bacteria, etc.) and aquatic algae produced thereby, while at the same time providing a safe habitat for algae predators and feeders in the form of minute animal organisms (e.g., crustacea, rotifers, snails, zooplankton, etc). The isolation and dispersion of the bark fiber clusters on the surface of the threatened bodies of water serves to prevent a disruptive imbalance between the algae and algal feeders by providing increased areas for life and surface breeding of various types of algae predators to thereby maintain essential trophic balance.
