Relevance of damages in <strong>the</strong> <strong>for</strong>est sector<br />
• Due to climate change, growth conditions will change and disturbances will<br />
increase (Seppälä et al. 2009, Thompson 2009).<br />
• The changes in climate are expected to increase droughts (Allen et al.<br />
2010) and storm damages (Gardiner et al. 2010).<br />
• According to a recently conducted enquiry among <strong>the</strong> Members of Standing<br />
Forestry Committee on behalf of Directorate General (DG) Environment on<br />
<strong>the</strong> major threats to European <strong>for</strong>ests, insects and storm/windfall have<br />
been identified as <strong>the</strong> most important damaging agents (Requardt et al.<br />
2007)<br />
• From 1950 to 2000 <strong>the</strong> annual average timber volume damaged by<br />
disturbances in European <strong>for</strong>ests was 35 million m³, caused 53% by<br />
storms, 16% by fire, 8% by bark beetles and 8% by o<strong>the</strong>r biotic factors<br />
(Schelhaas 2008).<br />
• Forest damage from storms <strong>for</strong> example can cause large economic losses<br />
to a country such as Germany, which experienced a storm in 2007 that<br />
affected approximately 20 million m3, and cost <strong>the</strong> country’s <strong>for</strong>estry<br />
industry about EURO 1 billion in lost revenue and damages (MCPFE 2007).<br />

Overall Outlook<br />
Storm damage mapping<br />
post event demonstration example is secured<br />
readiness <strong>for</strong> “real case” demonstration example<br />
ensuring fast delivery<br />
• linkage of user networks and EO data providers<br />
• production line ensuring fast delivery<br />
Bark beetle mapping<br />
trying to reduce <strong>the</strong> gap between user needs and EO capabilities<br />
Operational harvesting<br />
feasibility assessment to interest users outside <strong>the</strong> project user group<br />
