Table 2. Summary of estimated values for each service per wetland type derived from the value transfer exercise.
The total ecosystem service values per wetland type obtained from adding the median values per ES (in bold). Values in 2007 USD/ha/year.

Notes.
Extension of the wetland in hectares.
Annual ecosystem service flow was calculated multiplying the total ecosystem service value by the wetland area.
Total economic value (TEV) was calculated by adding the value of the annual flow of ecosystem services by wetland type.
Wetland description. Mangrove: forested-shrub estuarine wetland: plant association formed by one or a combination of the four species of mangrove; coastal lagoon: subtidal estuarine wetland; palustrine: palustrine continental wetland (where there is permanent water): swamp, marshes, tular, popal; riverine: permanent riverine wetland: rivers and channels; and lacustrine: lacustrine continental wetland, permanent and seasonal: lake, ponds, body of water.
