Do You Have Duckweed in Your Pond?

One of the leading threats to a pond is invasive plants and animals. A common threat is the duckweed–an organism with a humorous name that still poses a serious threat to your lake. Property management programs that include weed control for lakes should make getting rid of this organism a priority.

At the physical level, the common duckweed is a very small plant. It is light and free-floating, with leaves that can grow to the length of 1/8 inch. The leaves include roots that look like hairs. Although a single specimen of duckweed may only be comprised of several leaves, they grow quickly and can join with other duckweed to form colonies.

The duckweed is an aggressive invader and can infiltrate a lake in different ways. Many ducks eat duckweed and can transport it to other bodies of water. Another cause is eutrophication or algal blooms: an excess of nitrogen and phosphorous as a result of fertilizer runoff. They can enter a pond and provide an ample food source for existing duckweed to feed upon and reproduce.

Given its growth rate, a duckweed infestation is a common and persistent threat. Duckweed colonies can cover the entire surface of a lake and block sunlight from reaching aquatic plants. This leads to oxygen depletion, which kills plants and suffocates fish. As such, duckweed is a common cause of dead zones in lakes.

Weed control for lakes is an essential component of property management. Preventing a duckweed infestation does more than protect your lake’s ecosystem–it can also preserve its beauty and clear appearance.

The Important Facts about Eutrophication

Lakes have the potential to enhance the beauty, appeal, and value of a property. However, there are a variety of factors that can drastically reduce the health and appearance of your lake. Chief among those factors are environmental concerns, starting with eutrophication. In this post, we will talk about eutrophication and how it might influence your lake management program.

Eutrophication is the process in which a high concentration of nutrients–mainly nitrogen and phosphorous–infiltrate a body of water. These nutrients serve as a food source for microorganisms, algae, and plankton.

When food is abundant for these organisms, an algal bloom occurs. This can set off a chain reaction of new life entering the lake’s ecosystem, which also leads to a higher mortality rate among the population. Dead and decaying organisms sink to the bottom of the lake, and decomposition saps the water of oxygen. With the lack of oxygen, other life forms like fish and plants begin to die. Ultimately, it leads to a dead zone: a body of water where no aquatic animals can live.

Eutrophication occurs naturally in the wild. However, human activity can aggravate the process. Lawn care programs that use an excess of fertilizers can create nutrient-rich runoff that infiltrates bodies of water. Old or overworked septic tanks can also contribute to runoff. If your property borders a lake, then there is a good chance that your property is already a vector for eutrophication.

Taking action is always a better alternative than letting an algal bloom occur. A good lake management program does more than keep your lake clean and clear–it can also save wildlife and promote a healthier ecosystem.
