Portland's Non-Native Species Plan

There are many non-native species in Great Britain which are considered non-native as they have been transported outside their natural range. A small proportion are considered invasive. This is because of the damage they can cause to our environment, the economy, our health, property and resources. Key marine pathways for introduction include commercial shipping, recreational boating and aquaculture as examples. Biosecurity is about reducing the risk of introducing or spreading invasive nonnative species (and other harmful organisms such as diseases) in the wild.

Portland Harbour Authority have prepared an ‘Aquatic Invasive Non-Native (Alien) Species Plan’ that documents its understanding of invasive non-native species (and other harmful organisms such as diseases) in its jurisdiction and surroundings, considerations relating user interests, and potential measures going forward to improve understanding and reduce the overall risk.
