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


Conduct annual horizon scanning exercise to identify threats to the MPA not currently being managed. This will be achieved by reviewing activities underway or proposed in the Ascension MPA and the experience of other MPAs in the Blue Belt and Big Ocean networks. Newly-identified threats will be incorporated into management and monitoring workplans as appropriate.


New potential threats are identified and managed before they cause significant damage to the MPA.


Year 1: Threat assessment published

Year 5: Annual threat assessments published. Management and monitoring of all significant new threats incorporated into the next Annual Workplan and Monitoring Plan

Strategic objectives delivered
  1. To conserve Ascension Island’s marine biodiversity, habitats and ecological functions for long-term ecosystem health
Operational objectives delivered

1b. Proxy objective: Surveillance, compliance and enforcement regime effectively detects all known threats to offshore ecosystems

1d Proxy objective: Monitoring, regulation and management regime effectively tackles all known threats to inshore ecosystems
