Biotope mapping Gesäuse — Part report mapping area Gstatterstein

The biotope mapping was carried out on a scale of 1:2,000 from a minimum biotope size of 100 m with a minimum biotope width of 5 m. As mapping units, the biotopes were according to the “Red List of Endangered Biotope Types of Austria” (ESSL et al. 2002, 2004 & in Vorb.; Traxler et al. 2005) used. The images were documented in a survey sheet based on the biotope mapping Salzburg (NOWOTNY & Hinterstoisser 1994) and managed in an MS Access database. Biotopes that could be assigned to an endangered biotope type and/or habitat type according to the Habitats Directive (FFH-LRT according to Directive 92/43/EEC) were additionally documented with a list of species. Furthermore, the biotopes were digitally defined to colour orthophotos. 2002, 2004 & in Vorb.; Traxler et al. 2005) used.

Furthermore, the biotopes were digitally demarcated on colour orthophotos.In the Gstatterstein study area, 52 biotopes were mapped, which were detected on 161 individual areas (increased number of individual areas due to vegetation mosaic, especially in the area of the rock fall). The surface sizes of the individual biotopes range from 8 m (rock finders in the mountain fall area) to 13.5 ha (spruce forest on the northern slopes of the Gstatterstein).本次生境（biotope）制图采用1:2000比例尺，最小生境尺度为100米，最小生境宽度为5米。制图单元以《奥地利濒危生境类型红色名录》（ESSL等，2002、2004年及待刊；Traxler等，2005）中的生境分类为准。 影像数据基于萨尔茨堡生境制图规范（NOWOTNY与Hinterstoisser，1994）录入调查记录表，并于MS Access数据库中进行管理。对于可归类为符合《生境指令》（FFH-LRT根据欧盟指令92/43/EEC）规定的濒危生境类型或栖息地类型的生境，还需额外记录物种种群列表。此外，生境通过数字方式匹配至彩色正射影像。2002、2004年及待刊；Traxler等，2005年）采用。影像数据基于萨尔茨堡生境制图规范（NOWOTNY与Hinterstoisser，1994）录入调查记录表，并于MS Access数据库中进行管理。对于可归类为符合《生境指令》（FFH-LRT根据欧盟指令92/43/EEC）规定的濒危生境类型或栖息地类型的生境，还需额外记录物种种群列表。此外，生境通过数字方式从彩色正射影像中分离提取。本次生境制图采用1:2000比例尺，最小生境尺度为100米，最小生境宽度为5米。制图单元以《奥地利濒危生境类型红色名录》（ESSL等，2002、2004年及待刊；Traxler等，2005）中的生境分类为准。 本次生境制图采用1:2000比例尺，最小生境尺度为100米，最小生境宽度为5米。制图单元以《奥地利濒危生境类型红色名录》（ESSL等，2002、2004年及待刊；Traxler等，2005）中的生境分类为准。 影像数据基于萨尔茨堡生境制图规范（NOWOTNY与Hinterstoisser，1994）录入调查记录表，并于MS Access数据库中进行管理。对于可归类为符合《生境指令》（FFH-LRT根据欧盟指令92/43/EEC）规定的濒危生境类型或栖息地类型的生境，还需额外记录物种种群列表。此外，生境通过数字方式在彩色正射影像上进行划定。在格施塔特施泰因（Gstatterstein）研究区内，共完成52处生境的制图，这些生境分布于161个独立斑块中（独立斑块数量增加源于植被镶嵌体分布，尤其是落石区域）。单个生境的面积范围为8平方米（落石区的岩块生境）至13.5公顷（格施塔特施泰因北坡的云杉林）。
