A significant number of Baka Pygmies in Cameroon have been sedentarised in roadside villages, in contrast to their nomadic hunter-gatherer existence of the past. Although this change in lifestyle has had important consequences on health, most Baka villages still supplement their diets from forest products, especially wild meat. We used a combination of participatory methods and monitoring of individual hunters to map hunting territories in 10 Baka villages in southeastern Cameroon. From these, we determined whether wild meat extraction levels per village were related to the size of hunting territories, measured habitat use by hunters and finally defined the overlap between hunting territories and extractive industries in the region. Mapped village hunting areas averaged 205.2 ± 108.7 km (range 76.8-352.0 km); all villages used a total of 2052 km. From 295 tracks of 51 hunters, we showed that hunters travelled an average of 16.5 ± 13.5 km (range 0.9-89.8 km) from each village. Home ranges, derived from kernel utilization distributions, were correlated with village offtake levels, but hunter offtake and distance travelled were not significantly related, suggesting that enough prey was available even close to the villages. Hunters in all village areas exhibited a clear bias towards certain habitats, as indicated by positive Ivlev's index of selectivity values. We also showed that all village hunting territories and hunter home ranges fall within mining and logging concessions. Our results are important for local understanding of forest land uses and to reconcile these with the other land uses in the region to better inform decisions concerning land use policy and planning.
喀麦隆的大量巴卡俾格米人已经定居在路边村庄,与他们过去的游牧狩猎采集生活方式形成鲜明对比。尽管这种生活方式的改变对健康产生了重要影响,但大多数巴卡村庄仍从森林产品中补充食物,尤其是野味。我们使用参与式方法和监测个别猎人的方法,在喀麦隆东南部的 10 个巴卡村庄绘制了狩猎区地图。从中,我们确定了每个村庄的野味采集水平是否与狩猎区的大小有关,测量了猎人的栖息地利用情况,并最终定义了该地区狩猎区和采矿业之间的重叠。绘制的村庄狩猎区平均面积为 205.2±108.7 平方公里(范围 76.8-352.0 平方公里);所有村庄共使用了 2052 平方公里。从 51 名猎人的 295 条足迹中,我们发现猎人平均从每个村庄行进 16.5±13.5 公里(范围 0.9-89.8 公里)。从核密度利用分布中得出的家域与村庄的产量水平相关,但猎人的产量和行进距离没有显著相关,这表明即使在村庄附近也有足够的猎物。所有村庄地区的猎人都表现出对某些栖息地的明显偏好,这反映在选择性 Ivlev 指数值为正。我们还表明,所有村庄的狩猎区和猎人的家域都位于采矿和伐木特许权内。我们的研究结果对于了解当地森林土地利用情况非常重要,并有助于将这些情况与该地区的其他土地利用情况相协调,以更好地为土地利用政策和规划决策提供信息。
