Marxan was redeveloped in order to assist in the rezoning of the Great Barrier Reef, Australia, and was also used to quantify the tradeoffs between conservation and socio-economic factors in the Pacific Islands.

An international standard is to conserve 20% of all habitats by 2012. When planning conservation in the small Pacific Islands, the context is more unique due to their small size and heavy reliance on fishing and resources from the coral reefs. Compromises/tradeoffs are expected then, for both conservation and socio-economic /fishing. Marxan was used to be able to, for the first time, quantify these tradeoffs, and work out the optimal balance for conservation in the Pacific.
