Duckweed & Watermeal

Duckweed Identified

Duckweed and Watermeal are a nuisance vegetation with no true attached root system, this allows for the plants to float freely on top of the water surface and move to different areas in the aquatic ecosystem.  Both Duckweed and Watermeal also experience rapid reproduction meaning that once the plant has been introduced to the water body, it can take over quickly, limiting the ability for other aquatic vegetation to thrive.


Duckweed and Watermeal which fully covers the pond surface can also be dangerous for the ecosystem as they block the sunlight from reaching through the water column limiting photosynthesis, which in turn removes a lot of the oxygen production.  A lack of oxygen in an aquatic system can cause fish kills and also be fatal to other macro invertebrates in the water.  This can also mean difficulty on the treatment side of things as a water body can experience a massive drop in oxygen from treatment of significant duckweed or watermeal outbreaks.
