Location search and mapping of the ornamental plumage Dianthus plumarius subsp. blandus in the Gesäuse National Park

In May and June 2015, during the main flowering period, the already known occurrences of the ornamental spring nelke were visited in the Gesäuse National Park. In their surroundings, but also in other national park areas, by ascent, near and remote sensing (search and control with spotting and binoculars) were specifically searched for further (partial) populations in suitable trenches, rubble and open spaces. The obtained GPS data and the analog documentation of the found inventories on orthophotos from 2010 were merged in post-processing to determine population expansion. By combining our search methods, a current and accurate distribution picture of Dianthus plumarius subsp. blandus in the Gesäuse National Park was developed.2015年5月至6月正值主花期，研究人员于格塞瑙国家公园（Gesäuse National Park）内对已记载的春季观赏石竹（ornamental spring nelke）分布点开展实地走访调查。随后，研究团队不仅在这些植株的周边区域，还覆盖公园其他片区，通过徒步登高、辅以近距与远距观测（即借助瞄准镜与双筒望远镜开展搜寻与核查工作），针对适宜的沟谷、碎石地带与开阔空地展开专项排查，以找寻更多零散种群。研究人员将获取的GPS全球定位系统数据，与2010年正射影像（orthophotos）上标注的已发现种群调查清单的模拟存档资料进行后处理整合，以此分析种群扩张情况。通过整合本次采用的各类搜寻方法，最终构建出格塞瑙国家公园内羽毛石竹淡色亚种（Dianthus plumarius subsp. blandus）当前的精准分布格局。
