When one sets out to know your home, you can choose any thing you feel like to explore more. Today I chose something we used to dislike and call pond scum as it turned our pretty blue clear water farm ponds into green sloughs. We associated it with the dog days of summer -- an aesthetic blight on nature. Today we take a closer look
|Gathered at the south end of the pond, the duck weed has begun in its effort to cover the entire pond by summer's end.|
Wikipedia "Duckweed is an important high-protein food source for waterfowl and also is eaten by humans in some parts of Southeast Asia. As it contains more protein than soybeans, it is sometimes cited as a significant potential food source. The tiny plants provide cover for fry of many aquatic species. The plants are used as shelter by pond water species such as bullfrogs and bluegills. They also provide shade and, although frequently confused with them, can reduce certain light-generated growths of photoautotrophic algae.
The plants can provide nitrate removal, if cropped, and the duckweeds are important in the process of bioremediation because they grow rapidly, absorbing excess mineral nutrients, particularly nitrogen and phosphates. For these reasons they are touted as water purifiers of untapped value."
