Maple Ash Forests in Gesäuse National Park

This work is devoted to maple ash forests in the Gesäuse National Park. 31 vegetation images according to BRAUN-BLANQUET are used as a data base. A floor profile was also collected for all recording surfaces. Chemical parameters were also analysed for 23 soil horizons from ten profiles. In order to obtain an overview of the spread of maple ash forests in the Gesäuse, extensive site visits were made in July 2013. An indication of these explorations was the knowledge of forest ecological conditions in the area, acquired by the author in the course of several works since 2005. The focus areas of the maple ash forests were already known. In addition, areas were visited which, for reasons of relief or geological subsurface, suggested location conditions that promote precious wood. Furthermore, biotope mapping (KAMMERER 2007, 2008, Emmerer & KAMMERER 2010) was very helpful in researching suitable reception areas. Maps showing the distribution of the areas identified in the listed biotope mappings as maple ash forest were made available to the author by the nature conservation department Gesäuse National Park.本研究聚焦格劳泽国家公园（Gesäuse National Park）内的槭梣林（maple ash forest）。研究以依据布朗-布朗凯（Braun-Blanquet）植被调查法获取的31组植被影像作为基础数据库，同时为所有记录样地采集了地表剖面数据，并对10个土壤剖面中的23个土壤发生层（soil horizons）开展了化学参数分析。 为全面掌握格劳泽国家公园内槭梣林的分布范围，研究团队于2013年7月开展了大规模野外踏勘。本次调查的前期依据为作者自2005年以来多项研究中积累的该区域森林生态状况调研经验，且研究区域内槭梣林的核心分布区此前已被探明。 此外，研究团队还针对那些因地形或地下地质条件而具备珍贵用材林生长潜力的区域进行了踏勘。同时，生境制图（biotope mapping）（KAMMERER 2007、2008，Emmerer & KAMMERER 2010）可为筛选适宜生境提供关键支撑。格劳泽国家公园自然保护部门向作者提供了依据上述生境制图所识别出的槭梣林分布区域地图。
