To avoid erosion and reduce the level of silting in lakes, it is essential that the shoreland vegetation be conserved in its natural state. It prevents overfertilization The natural barrier which the shoreland vegetation provides against erosion has a double effect in that it also prevents overfertilization of the waters. The sediments, which could otherwise be carried into the water by rainwater run-off are generally very rich in those nutrients which nurture the growth of algae and aquatic plants. Thanks to the natural vegetal cover, however, these nutrients are recycled on the spot before ever reaching the water, by the on-shore plants which use them for their growth. To curb overfertilization of waters, the shoreland vegetation of lakes must be conserved in a natural state.
Warm waters favour the growth of algae and the proliferation of aquatic plants.
However, the shadows cast on the shallow waters by the shoreland vegetation and the coolness it effects prevent the warming of the shallow waters, even under direct sunlight. Consequently, the growth of algae and aquatic plants is slowed down. It protects the ecological balance Lakes are much more than just water. The forestial border, shores, shallows, and even the bed, are teaming with an incredible number of organisms which, with the water, constitute an ecological entity. The continual and vital interaction of all its inter-related parts is essential to maintaining the balance of any ecosystem.
