Abstract: Cost-effective conservation program design to support seasonal migratory species is urgently needed, but to-date has received little attention by economists. Conserving migratory corridors is a complicated design problem because of the large spatial scales over which migratory species can travel and the weakest-link characteristic of the problem. If one section or area of a potential migratory corridor is unable to support species movement, the migration through that route will not be successful. We develop and apply an integer-programming modeling approach that leverages innovative new data products to propose a cost-effective, landscape-scale conservation planning approach. We apply our approach to the Cody elk herd range within the Greater Yellowstone Ecosystem (GYE), leveraging satellite data on crop type and density over time and GPS collar data on elk migrations. We provide empirical evidence that using new satellite data products can avoid unconnected corridors and increase the cost effectiveness of corridor construction. In the Cody context, we estimate that achieving the conservation outcome associated with using satellite data on both costs and benefits would cost close to twice as much when using satellite benefit data but only limited cost data and about three times as much when using satellite cost data but only limited benefit data. Empirical work across additional herds is needed to provide additional insights into characteristics of contexts under which we expect gains from satellite and/or GPS collar data.
