Monitoring marine invasive non-native species

Non-native species (sometimes referred to as alien species) are those that have been introduced, either intentionally or unintentionally, outside of their natural range.

Non-native invasive species in the marine environment

There are considerable threats from invasive species in the marine environment. They can adversely impact on both economic activities such as our important aquaculture industry and on recreational activities such as boating, fishing, swimming and various other water-based leisure pursuits. Many aquatic species spread by hitching rides on the hulls of boats or on equipment and treatments to control hull fouling can be very costly. It is important to conform to the guidelines designed to minimise their spread. Environment and Marine Group (EMG),  organise and carry out regular marine monitoring programmes to detect non-native invasive species on our shores.

How you can help

Inspect all equipment that has been in a waterbody (boats, trailers, engines, outboards, dredgers, weed cutting or harvesting boats, cruisers or even clothing) or terrestrial site for attached vegetation, contaminated soil or obvious animal life before moving to another waterway, catchment or site

Remove any adhering plant, soil or animal material from your equipment before relocating to another watercourse, section of waterway or site. Ensure that all water is drained from your boat and equipment before transportation to another site and all soil is removed from machinery, as this may contain seed or plant fragments

Clean power hose all equipment. Use hot water (>60 degrees centigrade) where possible

Dispose of all plant material and animal material appropriately. This material should be contained in sealed bags or containers prior to removal. Do not throw them back into the water or leave them lying at the waters edge

Report any sightings of an invasive species on the Invasive Species Ireland website in the ‘Alienwatch’section or to the Pollution Hotline Number -  0800 807 060
