| The paper discusses the appropriate functional form and estimation technique for a wildlife production function on the farm level. A random effect model was developed to capture the relationship between wildlife output, management practices, natural conditions and non-observed factors that cause a farm specific management bias. Two wildlife measures were compared: species richness and a wildlife yardstick that enables different species to be weighed on their ecological value. The results show that the farm specific factor has a significant impact on the production of wildlife both in terms of species numbers and in terms of ecological values. Parameter estimates that were similar for the species richness specification were found to vary with the yardstick... |

| In order to guide conservation and restoration of wildlife in agricultural areas research is needed into the trade-off between wildlife and agricultural production and income. This study presents a location specific model for optimizing wildlife management on crop farms using the integer programming technique. Available data and indicators of wildlife production are presented. Furthermore, time and location aspects of wildlife management are discussed. The model is applied to crop farming in the Netherlands. Most important model outcome is a wildlife-cost frontier at the farm level. Model outcomes show that rotating wildlife conservation practices across the farm is economically more attractive than fixed-location practices. Opportunities for use of the... |
