Continuity forest or second-generation forest? Historic aerial photos provide evidence of early clear-cutting in northern Sweden
Modern forestry, which mainly consists of clear-cutting, is one of the most important factors influencing today's boreal forests. In Sweden, the breaking point for modern forestry is generally considered to be around 1950. Recently, our common knowledge of the implementation of clear-cutting in...

Modern forestry, which mainly consists of clear-cutting, is one of the most important factors influencing today's boreal forests. In Sweden, the breaking point for modern forestry is generally considered to be around 1950. Recently, our common knowledge of the implementation of clear-cutting in Sweden has increased, and new research indicates that clear-cutting systems were already applied before the 1950s. In this case study, we used aerial photographs from the 1940s to analyze the extent of contemporaneous clear-cuts and even-aged young forests in an area in northern Sweden. Our results show that almost 40% of the study area had already been clear-cut by the end of the 1940s, but also that clear-cutting had been applied to 10% of the forest land in the early 1900s.
