NI Water is calling on people using loughs, lakes and rivers this summer to take basic steps to prevent the spread of invasive species.

The utility says that with more boating, angling and paddleboarding taking place in August, there is a greater risk of moving invasive non-native species between water bodies. These organisms can travel in small amounts of water, mud or plant fragments on boats, clothing, footwear, fishing tackle and other equipment.

Once introduced, invasive species can damage native wildlife, lower water quality, block waterways and cause costly problems for water treatment infrastructure. NI Water is particularly concerned about zebra and quagga mussels, which attach to hard surfaces and spread quickly through connected waters.

Roy Taylor, catchment manager at NI Water, said August is one of the busiest periods for recreational use of waterways and that prevention is the best defence. He said invasive species can outcompete native plants and animals, alter habitats and clog screens, pipes and other equipment used to abstract and treat water.

The Check, Clean, Dry method asks people to check boats, equipment, footwear and clothing for mud, aquatic animals or plant material before leaving the water; clean everything thoroughly as soon as possible, paying attention to ropes, bilges, trailers and other damp areas, using hot water where possible; and dry all equipment and clothing for as long as possible before using it elsewhere, as some species can survive for days or weeks in moist conditions.
