Background
Bigger MPA are generally better Reserve effect on biological
measures appear to be independent of reserve size (Halpern 2003)
Palau’s community-based MPA development—smaller MPAs
Effectiveness of these MPAs have often been presumed given ban on extraction

Question and objective
Question: Are small MPAs in Palau effective?
Objective:Examine the effects of MPAs on fish density and biomass in 4 marine protected areas

Methods
3 stations inside MPA 3 station at the reference site
5 replicate 50x5m belt transects Targeted fish species

Conclusion
Small MPAs can be effective There are other factors to consider Level of enforcement Length of closure

Implications
Snap shots to trends—establishing long term monitoring
Addressing threats originating from outside the MPA
Networks of small MPAs Include social aspect—resource
users Improving management frameworks
and institutions
