economic value by function

The differences in per hectare values across wetland types are partly explained by the differences in the wetland functions that have been valued in these wetlands…
  • For example, un-vegetated sediment has largely been valued for its provision of storm protection, recreational opportunities and its role as a nursery ground for commercial fisheries – all highly valued services.
Many functions are characteristic of specific wetlands within specific regions…
  • For example, recreational fishing is a function that is dominant in wetlands in Europe and the United States, but not in many tropical wetlands.
