Fig. 2. Photographs of the same heathland valley side taken nearly two years apart, in the dry period 2006 and 2008. The black areas in the 2006 photo were newly burnt, and the border of one of those (a) has been highlighted with a white trace. The area below (b) was burnt in January 2008, and the fire stopped against the border of the then 2-year-old burn (a), only scorching the plants a few meters into the 2-year-old vegetation, seen as a brown fringe above the 2008 burn. This indicates an upslope wind during the burning, as is typical in the area. Likewise, the left-hand margin of the 2008 fire borders another 2006 burn. The length of the ring-shaped burn (a) is approximately 80 m.
