2. Description of the Related Art As various developments have been made in recent years, the shores of lakes and marshes are being filled up and being reveted with concrete, the waterside is becoming smaller. The animals and plants that exist there have played an important role in environmental conservation such as water purification,
If the habitat is lost, the chain of ecosystems will not work and environmental pollution will occur. Further, generally, the slope of the water-holding pond in artificial lakes such as dam lakes is steep, and because the history of water level fluctuations of several tens of meters makes it difficult for flora and fauna to settle, a waterside environment cannot exist.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a skeleton of an underwater floating reef with a width of about 2 meters made of metal and a length of about 3 meters and a height of about 20 cm. Attach the wire mesh 2 for the bottom to the bottom of the metric frame 1 and the wire mesh 3 for the side to prevent pebbles from spilling on the side.
Attach to form a basket. Metal fittings 5 for hanging from the float are attached to the peripheral corners. Pebbles, vegetation mats, etc. are laid on the bottom and used as an underwater floating reef. Furthermore, a float 4 for ensuring this weight in water may be attached.

FIG. 2 shows a second embodiment of the present invention in which a vegetation mat, pebbles and pseudo rock 7 are pasted on a substrate 6 such as FRP having a length and width of about 2 to 3 meters, and the pseudo rock is foamed. It may be one that has almost no weight in water such as concrete, or one whose core material is made of foamed plastic and whose surface is coated with resin, and which functions as a buoyant body in water. Alternatively, a float for reducing the underwater weight may be attached to the bottom surface.
