In our last blog we discussed a forest fire that had recently burned in the DAEMONS catchment. Last week Filip and Sara went hunting for the burned area but, after 3.5 hrs roaming the woods of Svartedalen nature reserve in the rain, gave up without any success. Subsequent inquiries with the fire brigade shed light on the problem: all media reports had placed the fire in the wrong place! The fire didn’t burn near Måkevatten, but occurred approximately 1.5 km away on the northern shores of Stora Holmevatten. Armed with this new information, Filip and Sara ventured out again and successfully found the fire area.
On the ground the fire burned an area of 300 m x 100 m, running right down to the lake shore. Small trees and shrubs have gone, but the larger pines look set to survive. A cursory investigation suggests that the fire didn’t penetrate too deeply into the soil; Filip and Sara reported that under a few centimeters of burned material was a normal looking FH horizon. They collected several samples from the lake and headwater streams which will be analysed for water chemistry to determine the local impact of the fire. The revised location of the fire means that the only DAEMONS sample sites that could possibly be affected will be the outflows of the Rördalsån and the Anråse. However, considering the small size of the fire, and the large size of the catchment, it seems extremely unlikely that any signal will be detected in the water chemistry. Comments are closed.
