Fur trapping is an important source of mortality for wolverine (Gulo gulo) in northern Canada. However, few populations are monitored for harvest sustainability. An examination of harvest data can be useful to identify areas of concern and direct appropriate management interventions. We used 27 years of harvest data (1988–2014) to examine patterns of wolverine harvest in the Yukon (Canada), where trapping permits are spatially explicit and there are no quotas. We identify spatiotemporal patterns in estimated harvest density, and trapping behavior by fur trappers. We also examined estimated harvest rates and availability of harvest refugia to evaluate if harvest was sustainable. The mean annual harvest in Yukon was 132 ± 31 wolverines, and there was no significant trend over time. Most trappers harvested wolverines infrequently, but 12% of trappers were responsible for 50% of all harvested wolverines, indicating that a small number of trappers had an influence on overall mortality. Relatively high mean annual harvest rates (≥ 8%) were estimated in several ecoregions in southwestern Yukon, where much of the human population and roads are concentrated. Conversely, estimated harvest rates were moderate to low (< 6%) in northern and eastern Yukon, which consist largely of remote wilderness. The mean percent area without harvest was 62 ± 16%. Sustained high harvest rates in southwestern Yukon are likely supported by dispersing animals from harvest refugia. Few putative harvest refugia were formally protected; rather, unsued trapping areas constituted temporal de facto harvest refugia. Our study points to the importance of harvest refugia and the persistence of wilderness regions for sustaining wolverine populations.

毛皮诱捕是狼獾死亡率的重要来源（Gulo gulo) 在加拿大北部。然而，很少有人监测收获的可持续性。对收获数据的检查有助于确定关注领域并指导适当的管理干预措施。我们使用 27 年的收获数据（1988-2014 年）来检查育空地区（加拿大）的狼獾收获模式，该地区的诱捕许可在空间上是明确的，并且没有配额。我们确定了估计的收获密度的时空模式，以及毛皮捕猎者的诱捕行为。我们还检查了估计的收获率和收获避难所的可用性，以评估收获是否可持续。育空地区的年平均收成为 132 ± 31 只狼獾，随着时间的推移没有明显的趋势。大多数捕猎者很少收获狼獾，但 12% 的捕猎者对所有收获的狼獾负有 50% 的责任，表明少数捕猎者对总体死亡率有影响。在育空地区西南部的几个生态区估计相对较高的年平均收成率（≥ 8%），那里大部分人口和道路集中。相反，在主要由偏远荒野组成的育空北部和东部，估计收获率从中等到低（< 6%）。未收获的平均百分比为 62 ± 16%。育空地区西南部持续的高收成率可能是由于动物从收成避难所中分散出来的。很少有假定的收获避难所受到正式保护；相反，未起诉的诱捕区构成了暂时的事实上的收获避难所。我们的研究指出了收获避难所的重要性和荒野地区对维持狼獾种群的持续性。
