Marine turtle species in the Asia-Pacific region face loss of habitat, population decline and serious risk of extinction. Understanding the associated loss in human welfare can motivate conservation finance, policy reforms and other actions to protect and restore marine turtle populations. This paper estimates non-use values for marine turtles in the Asia-Pacific region using a large-sample (n = 7765) global household survey. The survey focused on six countries in the region (China, Fiji, Indonesia, Malaysia, the Philippines and Vietnam) but received responses from over 80 countries in total. A discrete choice experiment was used to elicit willingness-to-pay (WTP) for marine turtles, defined in terms of population trends (increasing, stable or declining) and species diversity (avoided extinctions). We find that a high proportion of households (82%) expressed a positive WTP for turtle conservation, and that the donation …
