The diversity of marine protected areas that exists can be so mind-boggling that I sometimes find it difficult to imagine how they were ever grouped under one name! That name, ‘marine protected area’, broadly describes any part of the ocean that has been set aside for the conservation of nature. Some people consider these places true marine protected areas only if they are permanent; others recognise only no-take marine protected areas. Marine protected areas may only protect the sea floor, or conversely, only the water column above. They can be managed by governments or communities, NGOs or private enterprises. They can also be managed jointly.

A marine protected area for one species? Yes, that exists. Marine protected areas where trawling is allowed? They exist too. Marine protected areas smaller than 0.5 square kilometres (0.2 square miles)? Those exist. A marine protected area bigger than a country? Yup, that’s a real thing too.
One of the most useful ways for thinking about types of marine protected areas that I’ve come across splits them into groups based on who looks after and manages them, and how. This is not a perfect system – there is a continuous range of types of management for marine protected areas – but it helps to explain the diversity of protected areas in the ocean and group them into like piles, even if they are artificially neat.
