|Green turtle (Chelonia mydas) used as a proxy for the impact of MPAs on migratory species
|Natural Resource Unit
|Marine protected areas
|Somewhat unclear boundaries (2)
|Generally have known foraging and nesting grounds (The islands of Nusambier, Iwari, Kuwom, Matas and Wairundi and several mainland beaches have been recorded as turtle nesting beaches). But green turtles are a migratory species and found in tropical and subtropical waters so coded as somewhat unclear.
|["Status of highly migratory species"]
|Commons Unit Size
|Average weight of adult individual 68-190Kg
|Inter Annual Predictability
|Migratory but likely to return to particular nesting beaches every couple of years. Long-living. But vulnerable to rapid declines year on year if threatened by human activity.
|Intra Annual Predictability
|Availability varies according to season, but these patterns can be predicted. Also population sizes don't fluctuate too much in relation environmental factors.
|But slow to reproduce - low regeneration rates
|Poorly productive (1)
|Slow maturing, high infant mortality
|Very accessible (3)
|Turtles are easy to catch - intentionally or as bycatch. They are predicable with their nesting season when they and their eggs are easy to harvest
|Distributed in tropical and sub-tropical waters. Movements within the marine environment less well understood, but known to use a wide range of broadly separated localities and habitats during their lifetimes. But considered moderate as females return to same nesting beaches.
|Commons Spatial Extent
|13852km2 - coded here are size of Cenderwasih NP. But found across the entire info-pacific ocean
