The South Atlantic Conservation Blueprint is a living spatial plan to conserve natural and cultural resources for future generations. It identifies shared conservation priorities across the South Atlantic region. The third iteration of the Blueprint, Version 2.1, was released in August 2016. It used comparable methods and the same spatial scale as Blueprint 2.0, just incorporating updated information for many of the indicators. Version 2.1 was a completely data-driven plan based on ecosystem indicator models for terrestrial, freshwater, and marine environments, as well as a connectivity analysis. It used a 200 m spatial scale. More than 400 people from 100 organizations participated in the development of the Blueprint up to this point.
