Biotope mapping Gesäuse — part area Haglwald, Plattental, Wandau

In August 2013, the survey area “Haglwald, Plattental, Wandaubauernkar” in the Gesäuse National Park was mapped on a total area of just under 230 hectares on a scale of 1:2,000. As a result, a comprehensive biotope mapping based on the biotope type catalogue of Styria in the altitude range between 480 and 1.550 m is available. 33 different biotope types were detected on 656 individual surfaces. 12 FFH habitat types could be occupied on more than 80 % of the mapping area. Almost half of the area is built up by natural to natural book-dominated forests of the types Carbonateschutt-Fichten-Trnen-Buchenwald or mesophile lime-beech forest. A thermophilic lime beech forest could be documented as a rarer biotope type above the country wall up to the slope-crossing forest. About an eighth of the mapping area forms spruce forests, mostly as edaphic permanent societies on dry extreme locations over rugged forms of Dachstein limestone. Another area box consists of open to closed or stable high-mountain carbonate grasslands, characterised by Sesleria caerulea, Carex sempervirens and Helictotrichon parlatorei, which are extensively formed in the wall-builder’s car. On the highest positions of the backs are usually latschen bushes. The often wide avalanche channels are often lined with rimless legbeech bush forests. Isolated lower locations above Zwanzenbichl to the Lime Valley carry heavily anthropogenic overformed forest stocks with dominant spruce. The historical consideration of the development of the area over the past 130 years also demonstrates a high degree of proximity to nature for this study area, with the exception of some areas in the Haglwald forest of the middle and lower locations of the Kitzberg.2013年8月，科研人员对格绍国家公园（Gesäuse National Park）内的调查区域“哈格瓦尔德、普拉塔尔、万道博恩卡尔（Haglwald, Plattental, Wandaubauernkar）”开展了总面积近230公顷、比例尺为1:2000的测绘工作。本次测绘基于施蒂利亚州（Styria）生境（biotope）类型名录，在海拔480米至1550米的区间内完成了全面的生境制图，最终在656个独立地块中识别出33种不同的生境类型。 12种欧盟动植物生境指令（FFH）生境类型在超过80%的测绘区域内均有分布。近半数区域为以原生自然林为主的林分，具体包括碳酸盐碎屑云杉-桤木-山毛榉林（Carbonateschutt-Fichten-Trnen-Buchenwald）或中温石灰山毛榉林两类。沿岩壁直至跨坡林带的区域内，曾记录到一种作为稀有生境类型的嗜温石灰山毛榉林。约八分之一的测绘区域为云杉林，其多为生长在达赫施泰因（Dachstein）崎岖石灰岩裸露区极端干旱生境下的土壤依赖性永久群落。 另一部分区域为开放至封闭的稳定高山碳酸盐草甸，以蓝穗薹草（Sesleria caerulea）、常绿薹草（Carex sempervirens）和帕氏异燕麦（Helictotrichon parlatorei）为优势物种，该类草甸广泛分布于岩壁营建区内。在山脊的最高处通常分布有碎石坡灌丛。宽阔的雪崩通道两侧常生长有无柄山毛榉灌丛。位于茨旺曾比赫尔（Zwanzenbichl）上方至石灰谷的孤立低地内，分布着以云杉为优势种、受人类活动强烈干扰的改造林分。 对该区域过去130年的发展历史进行追溯后可知，除基茨伯格中下部区域的哈格瓦尔德林部分地块外，本研究区域整体具有极高的自然贴近度。
