At MPAtlas.org, we’ve taken the World Database on Protected Areas (WDPA) data as a starting point and examined certain regions in depth, replacing WDPA records with national or regional databases that are more up-to-date or provide greater detail (e.g., using the NOAA MPA Center inventory for US sites) and performing additional corrections based on original research.
Our data differs from other databases due to the way we require full implementation prior to considering an MPA in our numbers. We consider sites that have been formally designated but currently unimplemented and proposed sites seperately so that our numbers reflect as accurately as possible the actual amount of protection "on the water." We also report on strongly protected marine protected areas as a subset of the total coverage, where at least some of the MPA prohibits extraction of resources through fishing, mining and resource exploration, as we believe the level of marine protection we need globally needs to mitigate direct human impacts as much as possible.
|MPA Type||Other terms||No-take||Subsistence Extraction Allowed||Fishing Restrictions||Access Restrictions||Permanence||Other Activities|
|Fully protected (No-Take)||Marine reserves||Yes, Fully no-take||PROHIBITED||PROHIBITED||May be regulated||Yes (> 20 years). Year-round||no extraction of living or non-living resources – scientific collecting with permit ok|
|Strongly protected||May have some no-take zones with buffer||RESTRICTED
Recreational: RESTRICTED, allowed with permit and quantifiable as very limited take, no bottom trawling
|May be regulated||Yes (> 20 years). Year-round|
limited gears, sustainable fishing
|Other MPA||Marine parks||No||Yes||Any||No restrictions||Year-round|
|Non-MPA||FMAs, marine mammal/shark sanctuaries,OECMs||No||Yes||Any||No restrictions||Seasonal, temporary||no limits on extraction|
|Implemented||In force||Post-review||Boundaries/zones finalized|
|Designated||Established under competent authority, may implement at future date||Legal designation post-review, but management plan and zoning may be subject to review.||Boundaries finalized, may still need zoning details.|
|Proposed||Being developed||In progress, public input||Boundaries proposed|

This is a step by step guide on the method used to calculate global protected areas coverage in www.mpatlas.org.
To complete a successful analyses it is fundamental to check and repair geometry before running major calculations and to run topology tests to identify any duplicates or geometry issues. This is a simplified methodology, if you have any further questions please contact us at firstname.lastname@example.org.
