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. |

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS The concept of the present invention will be best understood in conjunction with a description of preferred means for carrying out my new ecological method. In the embodiment illustrated in FIGS. 1 through 4, a plurality of organic float means 10 are shown in position on the surface of a body of water 12. The separate float means are positioned between two spaced apart float members 14 by lines or stringers 16 which, as illustrated, can be secured to the float members by any suitable means such as air-driven staples 18. The float members 14 are held in place by end straps 20 which encircle vertical stakes 22 driven or otherwise positioned in the bottom of the body of water 12 (see FIG. 4). Preferably, conventional materials of construction are employed. By way of illustration, the float members 14 can be wood, the stakes 22 can be conventional fence posts of metal or plastic, and the straps 20 can be leather, plastic, metal, composition material or the like, suitably held in place by screws, nails or other fastening means 24. The stringers 16 can likewise be nylon cord, fishline, coated wire or similar material. In general, the construction should be rugged and simple so as to withstand weathering, wave action and other natural conditions and forces. In this regard, the stringers 16 are provided with a certain degree of slackness to accommodate relative movements of the float means 10 whereas the straps 20 permit necessary vertical movements of the float members 14 with respect to the positioning stakes 22. Referring particularly to FIGS. 2 through 4, the organic float means 10 may comprise a plurality of flat disks 26, of a specific density less than that of water, which may be suitably joined together to form a flotation unit. As illustrated, the disks 26 may be of a flattened cylindrical construction with one edge shaved off, as at 27, to provide flat adjoining surfaces which facilitate assembly. By joining two layers of disks rotated approximately 90
