Eradication of Invasive Weed, Dundrum Angling Club

The main aim of the project is Aquatic weed control at Dundrum Dam. The Dam is infested with Curly leaved waterweed (Lagarosiphon major), which is a non-native, invasive species. L. Major is native to Southern Africa, where it is also a nuisance weed species. it is often sold in aquatic garden centers under the incorrect name of Elodea crispa (there is no such species). It can be an aggressive weed in still or slow-flowing waters and has tended to increase at the expense of two other alien submerged aquatics, Canadian pondweed and Nuttall’s pondweed (Elodea canadensis and E Nuttallii). The project proposes the use of biodegradable jute material to eradicate the highly invasive weed by means of excluding light. This technique has been used in the South of Ireland successfully.
