Different plants and animals are adapted to life in fast or slow currents, deep or shallow water, rocky, sandy or muddy bottoms, and various amounts of light, oxygen or anaerobic conditions. Some aquatic plants cast their pollen on the surface to float to waiting flowers. And most have large buoyant tubers or seeds that float away to lodge elsewhere and propagate the species. Even the very muck on the bottom is marvelous, for in it dwell reducing bacteria so necessary in the cycle of life. The reducing bacteria in mud live by changing all those oxidized substances back into their reduced state.
Wetlands are truly awesome.
So instead of fretting over that big puddle or wet ditch, look to Nature. Find the plants adapted to wetlands and create a 'sump pump garden,' a mudflat, a marsh or trickling stream and watch the wildlife teem to your yard.
