Comparison of the planting success and risks of pine weevil damage on mineral soil and drained peatland sites three years after planting

Over 20% of regeneration operations will be on drained peatland in the next decade Finland. There are only a few studies comparing planting success and risk pine weevil ( (L.) feeding damage mineral soil peatland. Thirty sites planted with Norway spruce H. Karst.) container seedlings 2009 Southern Central Finland were inventoried three growing seasons after planting. Prediction models for probability survival, presence ground vegetation cover done separately sites. The was 17% lower (1379 surviving ha) than (1654 ha). factors explaining survival type spot peatland, soil. On soil, 76% spots cultivated while 28% similar spots. also fewer that surrounded by dense (4%) (14%). Pine did not differ significantly (23%) or (18%). more time there from clear-cutting, reduced both classes. Additionally, vicinity increased Cultivated spots, especially those covered prevented harmful effects peatland.Hylobius abetisPicea abiesâ??1â??1
