Please provide some details if your safety measures are based on potential consequences (damage potential,
value of endangered infrastructure, who performs such analyses for which hazards):
Safety measures are present in the PAR, however there is no cadastre of different safety measures and no
regular monitoring and analysis for different hazards.
Please provide insights into your site-specific forest management strategy (e.g. owner structure,
responsibilities/procedures for managing protection forest, collaboration with other “natural hazard actors”)
The forest management strategies are regulated by the Slovenian Forest Service.

MAJOR DAMAGE caused by natural hazard:
- The last major damage (mostly damage on agricultural fields – now there would be many houses) by
the torrent „Große Laine (Wildbachlaine)“ in 1915
- The forests (>90 % pure spruce) are highly prone to windthrows… neverless there have been only
minor damage during Vivian/Wiebke 1990 & Lothar 1990
- The „Bundesstraße B23“ has experienced smaller rockfalls in the area of the „Bärenhöhle“ – a hiking
trail was closed due to the rockfall danger

Please provide some details if your safety measures are based on potential consequences (damage potential,
value of endangered infrastructure, who performs such analyses for which hazards):
- Watershed Authority has the duty to provide security against the 100-year event (including a 15%
surplus for climate change adaptation). Cost-Benefit-Analysis are used within the administration to
prioritize different projects.
- Protection forest management (subsidized or planned by the forest service) focus on the stand structure
and stand dynamics. Damage potential is not considered systematically.
- The geological bureau (within the Landesamt für Umwelt) has created a hazard map
(Gefahrenhinweiskarte) – active measures are erected by the road administration, the municipality or
the land owner based on individual assessments.
Please provide insights into your site-specific forest management strategy (e.g. owner structure,
responsibilities/procedures for managing protection forest, collaboration with other “natural hazard actors”)
We have 4 major forest owners:
- Privatwaldgemeinschaft Oberammergau (1800 ha) – cooperative with over 200 members – organized
like a modern forest enterprise (employees: forester + professional hunter)
Administration at state or federal level & representation of interests

Please provide some details if your safety measures are based on potential consequences (damage potential,
value of endangered infrastructure, who performs such analyses for which hazards):
Vals
- On the basis of the rock avalanche in 2017, a tunnel and the alteration of the street line was planned
- Currently, there are 3 dams existing for rockfall protection and 2 dams avoiding torrent and avalanche
damages
- Currently, there are a few hundred meters of rockfall nets and avalanche control fences
- After flooding, in 2013 foodbanks where built in the centre of the village St. Jodok
Gries
- After flood events and landslides in 2002, 2007, 2008 and 2012 buildings were badly damaged; the
Austrian service for torrents and avalanche control settled measures e.g. in the river zones
- technical safety measures in the Venntal are (because of the extreme relief) not possible
- The touristic usage of one of the gastronomic companies has been adjusted
