Limnological Concept Gesäuse Phase I

This study presents phase 1 of the two-phase project management for the creation of a Limnological concept for the Gesäuse National Park. The basis for the drafting of the concept is the 6(2) of the National Park Ordinance, which states: The National Park Administration has to draw up a limnological concept and implement it within the framework of fisheries legislation. On the basis of this concept, the conservation of natural biodiversity and genetic variability, as well as the progress of domestic livestock, will be ensured and promoted. In its basic concept, which is stipulated by the tender documents of February 2008, the concept clearly transcends the technical framework of Limnology and, in addition to the protected products of the water itself, also deals with the river-shaped accompanying habitats and their conservation-relevant species equipment. This extended thematic reference applies in particular to phase 1, which includes the documentation and evaluation of the actual status, the preparation of a catalogue of measures and the preparation of a monitoring plan for the protected goods listed in the tendering procedure. For Phase 2, surveys of the macrozoo and phytobenthos and the assessment of the ecological status of waters under the Water Framework Directive provide for a focus on the limnological aspects i.e. The development of phase 1 of the concept is entirely based on the literature on the individual protected goods. Own mappings or surveys on site are not provided in this phase of the project, their own expert interpretations are provided only to a limited extent.本研究阐述了为格萨厄国家公园（Gesäuse National Park）制定湖沼学（Limnology）概念的两阶段项目管理第一阶段工作。本概念的起草依据为《国家公园条例》第6条第2款，其中明确规定：国家公园管理部门需制定湖沼学概念，并在渔业立法框架内予以落实。基于该概念，将保障并推动自然生物多样性与遗传变异的保护，以及家畜养殖的发展。 根据2008年2月招标文件规定的基本框架，本概念已超出湖沼学的技术范畴：除保护水体本身的保护对象外，还涵盖河流状伴生栖息地及其与保护相关的物种组成。这一拓展的主题范围尤其适用于第一阶段工作，该阶段包括对招标流程中列明的保护对象的实际现状进行建档与评估、编制措施清单，以及制定监测计划。 对于第二阶段，针对大型动物群（macrozoo）与底栖植物群（phytobenthos）的调查，以及依据《水框架指令》（Water Framework Directive）开展的水体生态现状评估，均聚焦于湖沼学相关维度，即本概念第一阶段的制定完全基于各保护对象的相关文献。本阶段项目无需开展实地测绘与现场调查，且仅能在有限范围内提供自主的专家解读。
