Survey of the river banks in Gesäuse National Park

The aim of this thesis is to collect the current stock of the riverside runner in the Gesäuse National Park and to describe its stock development and hazard situation, as well as to develop measures for future conservation of stocks and proposals for monitoring and further research priorities. The controls from 21.6.2003 showed a minimum stock of 2 pairs or a maximum stock of 4 pairs. However, no indication of a successful breeding could be provided anywhere.本学位论文的研究目标为：调研格绍伊国家公园（Gesäuse National Park）内河畔行者（riverside runner）的现存种群（stock）规模，阐明该种群的动态变化与受胁现状，制定后续种群保护措施，并提出监测建议与重点研究方向。2003年6月21日开展的调查结果显示，该种群的数量区间为2对至4对，即最低2对、最高4对，但未在任何区域观测到该种群成功繁殖的迹象。
