Biosecurity

Portland Harbour Authority has developed an ‘Aquatic Invasive Non-Native Species Plan’ to address the risks posed by invasive species, protect the environment and encourage public reporting of sightings.

Aquatic Invasive Non-native (Alien) Species

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 non-native species (and other harmful organisms such as diseases) in the wild.

With this in mind, 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.

The first version (June 2019) of the plan can be downloaded from the sidebar along with the associated tables. In case of the tables, these have been updated and are referred to as version September 2020.

Please report any records of species that you consider may be invasive to Portland Harbour Authority using the following email env@portland-port.co.uk
