Failure to coordinate management in transboundary populations hinders the achievement of national management goals: The case of wolverines in Scandinavia

摘要: Large carnivores are expanding in Europe, and their return is associated with conflicts that often result policies to regulate population size through culling. Being wide‐ranging species, populations distributed across several jurisdictions, which may vary the extent they use lethal control. This creates conditions for establishment of source‐sink dynamics borders, frustrate ability countries reach respective management objectives. To explore consequences this issue, we constructed a vec‐permutation projection model, applied case wolverines south‐central Scandinavia, shared between Norway (where culled) Sweden protected). We evaluated effect compensatory immigration on wolverine growth rates, if was influenced by distance national border. assessed what had an influence number removals needed keep at given rate. In Norway, model estimated stable trend, whereas it produced 10% annual increase. The corresponded 0.02 reduction rate similar increase Norway. strong closer Norwegian‐Swedish border, but weak when moving away from it. An average 33 shot per year Norwegian part study area. If no occurred, 28 would have been sufficient achieve same goal. About 15.5% all individuals harvested 2005 2012 were compensated immigrants, causing decrease Sweden. Synthesis applications. When transboundary, decisions also even though political bodies charge those decisions, stakeholders who them, taxpayers finance them not.
