Using novel collective agri-environmental scheme data from a species protection measure this paper
investigates the environmental effectiveness of a cAES approach for a spatially defined biodiversity
dilemma. However, individual agri-environmental schemes have not shown effective in assuring a
spatially connected corridor of favorable habitat for the species. As an umbrella species to the local
ecosystem, protection of the European hamster in Alsace is relevant in at least two aspects: (1) The
need for protection of the endangered species may provoke alternative farming practices that are more
sustainable for the local ecosystem as a whole and serve many threatened species in this
intensively-managed agricultural landscape. (2) Due to its habitat in agricultural landscapes, the
dilemma of the European hamster in Alsace has the potential to highlight the problems of intensive
farming practices for biodiversity in this region. The results of the collective scheme show that
cooperation among farmers across a common territory benefits from (i) the presence of a moderating
farmer association, (ii) flexibility in contract design and (iii) visibility of environmental outcomes
achieved through the scheme.
