Our study production, and farm size were important factors that examined habitat factors associated with amphibian affected wetland habitat use by geese. The management reproduction at two spatial scales: the pond and the styles of farmers affected the quality of wetland habitat landscape surrounding the pond. We found that small when policy scenarios required rice to be grown with agricultural ponds in southeastern Minnesota provided conventional production methods. In this case, farmers, breeding habitat for at least 10 species of amphibians. particularly those who were concerned about maintaining Species richness and multispecies reproductive success farming as a way of life, continued rice production and were more closely associated with characteristics of the maintained wetland habitat for geese even when crop pond (water quality, vegetation, and predators) compared subsidies decreased over time. The public benefited from with characteristics of the surrounding landscape, but the decision making of these farmers because the individual species were associated with both pond and important indirect use value (wildlife habitat and water landscape variables.
