Book Thinning of Scots Pine and Norway Spruce Monocultures in Sweden

Download or read book Thinning of Scots Pine and Norway Spruce Monocultures in Sweden written by Urban Nilsson and published by . This book was released on 2010 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of thinning intensity, thinning interval, thinning form and timing of the first thinning on stand level gross- and net stem volume production in Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L. Karst) was investigated in a nationwide field experiment across Sweden. In total, 35 Scots pine sites distributed from the south to the north of Sweden and 13 Norway spruce sites located in the south and central parts of Sweden were investigated. Thinning treatments ranged from unthinned control, to light and moderate repeated thinnings, to a treatment where 60-70% of the basal area was removed in a single thinning. In addition, thinning from above was compared to thinning from below and delayed first thinning was compared to early first thinning. The average measurement period was 31 years for Scots pine and 30 years for Norway spruce. All Scots pine thinning treatments reduced the total gross stem volume production compared to the unthinned control, whereas only the heaviest thinning treatments, in which a large proportion of the basal area was removed, reduced the total gross stem volume production for Norway spruce. Thinning from above did not affect total gross stem volume production of Scots pine, but there was a tendency towards lower production in Norway spruce. For Norway spruce, thinning from above resulted in lower net stem volume production than thinning from below. Delaying the first thinning did not affect gross stem volume production for either Scots pine or Norway spruce. Net volume production and volume production in trees with diameter at breast height> 8 cm was higher for the light thinning treatment than for the unthinned control in Norway spruce. In Scots pine, there was no difference between the light thinning treatment and unthinned control in net volume production. For cots pine, the heavy thinning treatments decreased net volume production compared to the unthinned threatment whereas there were no differences in net volume production between the heavy thinning treatments and unthinned control in Norway spruce.

Book Continuous Cover Forestry

Download or read book Continuous Cover Forestry written by Timo Pukkala and published by Springer Science & Business Media. This book was released on 2011-10-14 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the majority of the world’s forest ecosystems are dominated by uneven-sized multi-species stands, forest management practice and theory has focused on the development of plantation monocultures to maximize the supply of timber at low cost. Societal expectations are changing, however, and uneven-aged multi-species ecosystems, selectively managed as Continuous Cover Forestry (CCF), are often believed to be superior to monocultures in addressing a wide range of expectations. This book presents methods which are relevant to CCF management and planning: analysing forest structures, silvicultural and planning, economic evaluation, based on examples in Europe, Asia, Africa and North and South America.
