Coupling stakeholder assessments of ecosystem services with biophysical ecosystem properties reveals importance of social contexts

- Structural equation modelling identified relationships between stakeholder perceptions and measured ecosystem properties.
- Ecosystem service perceptions of farmers and conservationists differ significantly, due to different social contexts.
- Conservationists associated forage production with the actual land use, whereas farmers focused on the potential of ecosystem to produce forage.
- Farmers´ conservation perception was related to species richness, whereas conservationists associated conservation value with endangered meadow birds.
- Conservationists associated carbon sequestration value with below-ground peat formation, whereas farmers associated it with above-ground plant productivity.

We asked whether different stakeholders perceive ecosystem services in similar ways and how these perceptions relate to measured ecosystem properties. Farmers and conservationists were asked to state (1) their preference for ecosystem services and (2) their perception about the value of several grassland vegetation units in providing these services. Additionally, biophysical parameters were collected on 46 plots. Structural equation models were applied to test which stakeholder perceptions corresponded to the data.For conservationists, the services regional belonging and soil fertility were related to conservation value, whereas farmers associated them with forage production. Conservationists' perception of forage production was related to biomass removal, groundwater level and income from forage production, whereas farmers focused on the potential of ecosystems to produce forage, rather than the actual land use. The conservation perception of farmers was related to low land use intensity, whereas the conservationists associated it with endangered meadow birds. Conservationists associated carbon sequestration with below-ground peat formation, but farmers with above-ground plant productivity.We conclude that perceptions of ecosystem services are strongly influenced by social contexts, involving livelihoods, interests and traditions. Use of stakeholder assessments to establish sustainable land management should consider the fact that stakeholders interpret ecosystem services with different meanings.
