Rätt planta på rätt trakt : undersökning av Bergvik Skogs planterade hyggen

Sammanfattning: This report is based on a study of Bergvik Skog's planted cuttings in 2018. The purpose of the study was to find out if Bergvik Skog is planting the right seedlings on their planting sites. By the right plant is meant that the planted plant is of the right tree species and provenance based on what is optimal on the area. Access to data from Bergvik's forest register and planting follow-ups was published in Excel format. The material included planting follow-ups contained data from the last 10 years. Sampling inventory of planting follow-ups was done over the entire Bergvik forest holdings. The purpose was to find out if the right tree species was planted at the determined site preference. When examining the forest register, the aim was to investigate whether the right choice of provenance was used based on what the research says. As well as find out if the right tree species has been planted based on the determined site preference for each site. During the period 2009-2018, a total of 602 planting sites within Bergvik Skog were inventoried. Of which two of these planting sites were decided to change the site preference. During the planting season in 2018, a total of 2850 plants were planted on Bergvik Skog's planting sites, of which 93 percent was planted with the right tree species. The result of the study showed that Bergviks Skog's use of provenance displacement is largely in line with what today's research recommends. Cultivation material for Norway spruce and Lodgepole pine is completely moved according to today's recommendations. 6.9 percent of the cultivation material for Scots pine with known provenance in altitude and latitude has been moved north and to a higher altitude, which does not follow the lines of research.
