摘要：Global wetland loss has reduced biodiversity and ecosystem services. These declines have inspired many landholders to restore wetlands, but the success of these efforts remains unclear, in part, because quantifying ecosystem services requires diverse methods. Here, we blend participatory mapping and surveys, field measurements and high-resolution models to track ecosystem services from restored wetlands on private land. We ask: 1) What ecosystem services do people perceive from restored wetlands? 2) What modelled/field measured ecosystem services were enhanced through restoration? and 3) How do field measured, modelled and perceived ecosystem services in restored wetlands interact? Participating landholders mapped their restoration project and shared their perceptions of ecosystem services. Next, we modelled ecosystem service changes using the Land Use Capability Indicator (LUCI) model and contrasted these to field measured ecosystem services for each wetland. Landholders perceived ~6.5 services from their restored wetlands. For modelled services, restoration significantly enhanced nitrogen and phosphorous retention. For fieldmeasured services, restoration increased soil organic carbon by ~20%, soil permeability to water by ~27% and native plant species richness by ~15 species, while reducing plantavailable phosphorous by ~23%. Correlating across methods revealed that reduced plantavailable phosphorus and site age and size were associated with more perceived services, whereas an increase in plant species richness was not a good proxy for gains in measured, modelled or perceived services. Based on the diverse ecosystem services gained, demonstrated by multiple methods, we contend that private wetland restoration can be successful as well as leveraged to meet multiple management and policy objectives.
