Alien species are plants or animals that aren’t native and have been introduced, usually by people, outside their natural range or habitats. They can sometimes become ‘invasive’ when they spread rapidly and out- compete the native flora and fauna. Invasive species present a significant threat to biodiversity worldwide.
Invasive species can be particularly problematic in wetland habitats. They can have negative impacts on recreational and amenity use of waterways as well as threatening native ecosystems.
The National Biodiversity Data Centre (NBDC) prepared reports in 2010 on invasive species for each county in Ireland. Called the Dirty Dozen Report it identifies 12 problematic invasive species in each county, chosen based on their presence in the county and their potential for impact and spread.
