The forest lying above the municipality of Hallstatt, Upper Austria, the “Bannwald Hallstatt”, has the function to protect the township and the underlying street as well as the so-called “Sole-Leitung”, which transports the salt extracted from the mine in Hallstatt, against rock fall and avalanches. This thesis was part of a study of the Institute of Silviculture, which established a tool for evaluating measures in protective forests. The study was commissioned by the Austrian Service of Torrent and Avalanche Control in Bad Ischl, Upper Austria, which is in charge of the protective forest in Hallstatt. The outcome of the study is an assessment which shows the condition of the technical, silvicultural and soil-bioengineering measures taken in the “Bannwald Hallstatt” and is displayed in a 3 grade traffic light system. This thesis deals particularly with the GIS-based illustration of the results in thematic maps and a concept for the avalanche catching dam of the “Steingraben”-avalanche, which was built with soil-bioengineering techniques, as well as the surrounding area, which is highly effected by soil erosion. The results of the evaluation show that the protective function of the stand against avalanches and rock fall is restricted. The young stands are poorly developed because of browsing and damages through rock fall and gliding snow. Older afforestations are well evolved. The technical protection measures are in good condition, although silvicultural measures have to be taken to ensure that the forest can sustain a part of the protective function, when the technical measures are getting worse in the next few years. The avalanche catching dam of the “Steingraben”-avalanche is also in good condition, although it should be replanted. Also the erosion above the dam should be treated with soil-bioengineering measures to stabilize the slope.
