Strong anthropogenic signals in historic forest fire regime: a detailed spatiotemporal case study from south-central Norway
To better understand the historic range of variability in the fire regime of Fennoscandian boreal forests we cross-dated 736 fire scars of remnant Scots pine (Pinus sylvestris L.) wood samples in a 3.6 km 2 section of the Trillemarka-Rollagsfjell Reserve of south-central Norway. Using a kernel range...
