Results

• After Poland Germany is the most endangered area to forestfires in Central Europe

• Endangered are particularly the eastern federal states

From 858 FF in Germany 2009 there were 470 cases in East G.

• Particularly affected by forest fires is the federal state of Brandenburg

• Reasons are climatic conditions (driest state), associated with sandy soils which store very little precipitation

• In addition there is a high proportion of pine (70 %) which is particularly vulnerable concerning fires

Examples of

RS-Applications

• MODIS Active Fire Data is not suitable for a fire monitoring in

Germany

• According to aspect, there is influence visible to forest fires in

Brandenburg and Northern Portugal

• According to the infrastructure (road buffers) a influence could be also confirmed

• Remote Sensing Data, especially MODIS, is very suitable for

research particulary on global scale
