Forest stakeholders have still faced very different risks for ages: pest, forest fires, storms, economic crisis, etc. But why do they emphasize certain risks while ignoring others? A survey of the same group of forest owners had been carried out before (2006) during (2009) and after (2012) the devastating windstorm Klaus that hit the Landes de Gascogne Forest. It shows that: The perception of risks change over time, and is partially embedded in culture and particularly in the historical background of the local communities that sometimes keep memory of disasters alive but also forget and erase painful events.The perception of risks also depends on the biophysical characteristics of the hazards (origin, intensity, resilience, etc.) and on the social characterization that is done by forest stakeholders. The survey shows that forest owners’ perception of risks is influenced both by the depth of scientific evidence or on the likelihood of danger but also by the voice that predominates in the evaluation and processing of information about hazardous issues. Finally, the presentation will show how some risks becomes public problems and are setting at the forest policy makers agenda while others are denied, marginalized or simply ignored.
