Computations on the yield of timber by Scots pine when subjected to varying levels of thinning under a changing climate in southern Finland

Abstract Model computations showed that climatic change in terms of rising temperature could increase the yield of Scots pine ( Pinus sylvestris ) stands in southern Finland (61° N) with a consequent need to shorten the rotation and revise the timing of commercial thinnings to take place earlier than under the current temperature conditions. Hence, under a rising temperature, the total timber yield could increase compared with that under the current temperature condition if the length of rotation is kept the same. The largest increase was obtained when several thinnings at low thinning levels were applied under a slowly rising temperature.
