Wetlands are important for biodiversity and are critical for human livelihoods, providing ecosystem services such as clean water, food and global climate regulation. Many wetlands are threatened by land-use conversion, but creating protected areas to conserve them can benefit both biodiversity and people. However, protected areas can also have socio-economic costs for local communities. At Koshi Tappu Wildlife Reserve in Nepal, there has been historical conflict over the creation of the reserve. In light of a recent proposal to expand the protected area, we explored the use of a rapid ecosystem service assessment tool (TESSA) to assess the impact of the reserve on some of the key ecosystem services the site provides. Based on the ecosystem services assessed we estimated that the economic value of KTWR as a protected area is $350,000 y−1 ($20 ha−1y−1) less than the value of the wetland in an unprotected state. However, this difference is relatively small and is affected by the limitations of the approach and sensitivity of the values to market prices and the assumptions made, so we cannot draw clear conclusions on the overall impact of the reserve in relation to local livelihoods. However, we found TESSA to be a useful tool for engaging with the stakeholder community and for highlighting the potential impacts that land use decisions can have on key ecosystem services. In the context of informing the potential expansion of the reserve, it is clear that further intensive socio-economic assessment of the potential costs and benefits is necessary.
