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月正值盛花期，研究团队于格塞奥国家公园（Gesäuse National Park）内，对该区域已记录的春季观赏石竹分布点开展实地考察。随后，在其分布周边乃至公园其他区域，通过徒步攀登、近距与远距探查（借助寻星镜与双筒望远镜开展搜寻排查），针对适宜的沟谷、碎石堆及开阔地带进行专项搜索，以发掘新增的（部分）种群。研究人员将获取的GPS数据，与2010年正射影像（orthophoto）上的人工记录种群档案进行后处理整合，以明确种群扩张态势。通过综合运用本次采用的多种搜索方法，最终构建出格塞奥国家公园内须苞石竹淡色亚种（Dianthus plumarius subsp. blandus）的最新精准分布图谱。
