This section describes the actions we will take to achieve the MPA’s objectives

This involves not only preventing or restricting damaging activities that threaten the MPA but also restoring, improving, researching and sharing Ascension’s amazing marine environment.

The MPA is going to be around forever and it will be a long journey to achieve everything we want. In the first five years covered by this plan, we have focused on the actions that will achieve the greatest positive change to the MPA within our resources (more detail of how we determined this is given in the MPA Showing our Workings document). This means there are no actions linked to substantial threats such as ocean acidification and rising sea temperatures because we simply don’t have the management tools to address them. It also means ambitious aspirations to develop Ascension as a global science hub will have to be achieved in stages and the futuristic submarine laboratory complex will have to wait until the next phase.

The designation of the MPA was underpinned by sound science and this evidence-based approach is carried forward into the management of the site. Where possible we have designed management actions based on existing data and experience of what will be effective. However, we know we don’t have all the answers from the start so targets, monitoring and refinement of our management will be essential. How we will do this is described in the Monitoring and Evaluation section.

The actions are arranged so that they can be filtered to show those that contribute to achieving different strategic or operational objectives, the ones that counter specific threats to the MPA and those actions that help protect particular species and habitats. Alternatively, you can choose to see them all and realise how busy we will be for the next five years.

Operational objective


Review and improve on-island pollution control measures and spill response capability through implementation of recommendations in the Marine Pollution Control Plan


Adequate control and mitigation measures in place for all known potential sources of pollution in the MPA


Year 1: Marine pollution control plan published and pollution response capability assessed by Maritime and Coastguard Agency.

Year 5: Adequate bunding and spill control measures in place around all fuel storage sites. Effective treatment and disposal of all waste effluents. Emergency spill containment plans and equipment in place.
