Distribution of caper chickens

The distribution map shows the state of the last mapping. Distribution maps for caper chicken deposits in the Black Forest have been produced since 1993, when a continuous documentation of all sightings and indications of the occurrence of caper chickens was started. In the course of 5 years, a new distribution map with the evidence collected during this period will be created. The caperhun distribution area is defined as areas for which at least three evidence is available within the last five years. The filled 3 x 3 km grid cells are based on various indications (sighting, annual court counting, faeces, feathers, hudder pans, step seals). For the sake of sensitivity of the bird species, the distribution is only published with a resolution of 3 x 3 km. The evidence comes from the FVA and is based both on its own investigations and on reports from hunters, foresters, forest workers, ornithologists and conservationists.本分布图展示了最新一次分布测绘的实际情况。 黑森林地区松鸡（caper chicken）的分布点位分布图自1993年起便已开始绘制，彼时研究人员启动了对该物种所有目击记录及出现迹象的持续建档工作。本次将基于五年间收集的各类佐证材料，绘制全新的松鸡分布分布图。caperhun分布区（caperhun）被定义为：近五年内至少存有三项佐证记录的区域。填色的3×3千米网格单元的绘制依据包括多种迹象：目击报告、年度求偶计数、粪便、羽毛、hudder盘、足迹印模。鉴于该鸟类物种的敏感性，本分布数据仅以3×3千米的分辨率对外发布。本研究的佐证材料均来自森林试验研究所（FVA），其数据既包含该机构自身的调查结果，也涵盖猎人、林务员、林业工人、鸟类学家以及自然保护主义者提交的各类报告。
