Formatted abstract
Establishing different types of conservation zones is becoming commonplace. However, spatial prioritization methods that
can accommodate multiple zones are poorly understood in theory and application. It is typically assumed that management
regulations across zones have differential levels of effectiveness (‘‘zone effectiveness’’) for biodiversity protection, but the
influence of zone effectiveness on achieving conservation targets has not yet been explored. Here, we consider the zone
effectiveness of three zones: permanent closure, partial protection, and open, for planning for the protection of five
different marine habitats in the Vatu-i-Ra Seascape, Fiji. We explore the impact of differential zone effectiveness on the
location and costs of conservation priorities. We assume that permanent closure zones are fully effective at protecting all
habitats, open zones do not contribute towards the conservation targets and partial protection zones lie between these two
extremes. We use four different estimates for zone effectiveness and three different estimates for zone cost of the partial
protection zone. To enhance the practical utility of the approach, we also explore how much of each traditional fishing
ground can remain open for fishing while still achieving conservation targets. Our results show that all of the high priority
areas for permanent closure zones would not be a high priority when the zone effectiveness of the partial protection zone is
equal to that of permanent closure zones. When differential zone effectiveness and costs are considered, the resulting
marine protected area network consequently increases in size, with more area allocated to permanent closure zones to
meet conservation targets. By distributing the loss of fishing opportunity equitably among local communities, we find that
84–88% of each traditional fishing ground can be left open while still meeting conservation targets. Finally, we summarize
the steps for developing marine zoning that accounts for zone effectiveness.
