Wildfires in Europe are predominantly caused by people visiting natural areas. The hazards as a result of wildfires increase particularly in densely populated areas such as Europe, since more and more people visit natural areas. The circumstances for large wildfires to occur are predominantly located in countries surrounding the Mediterranean Sea. In these countries on average 1% of their natural area resources are affected by wildfires each year. Typically, a few percent of the total number of fires is responsible for more than 95% of the total area burned. The fire season is usually during the summer and early fall. The risks for wildfires in the northern European countries are generally much lower. Typically, 0.1 - 0.2% of the total natural area is burned each year. The main season for wildfires is early spring. The interest of the authorities, that are responsible for the natural areas, in the northern European countries for autonomous wildfire surveillance is high since the efficiency of the current wildfire surveillance, such as from airplanes and lookouts, is often unsatisfactory.
