21. The puzzle of forestry and cervid interactions : a missing piece is in the understory
Abstract : Shrubs of the family Ericaceae, including bilberry (Vaccinium myrtillus), cowberry (V. vitisidaea) and heather (Calluna vulgaris), often dominate the understory in Eurasian boreal and cold-temperate forests. READ MORE

22. Oak as retention tree in commercial spruce forests : effects on species diversity of Saproxylic beetles and wood production
Abstract : Retaining trees valuable for biodiversity is a common conservation measure. There are indications that such trees have important benefits for the diversity of many species groups. However, retaining trees may also have negative effects on timber production. READ MORE

23. Clonal propagation of Detarium microcarpum and Khaya senegalensis : a step toward clonal forestry in Burkina Faso
Abstract : The slow growth of seedlings and the impact of insect pests are major limitations to the use of indigenous species in plantations in Burkina Faso. Thus, the use of vegetative propagules and resistant clones may enhance the success of plantations. READ MORE

24. Old trees in young forests : Biodiversity management in planted conifer forests in southern Sweden
Abstract : Sweden’s long history of intensive forest management has made conservation measures in the forest landscape necessary to counteract the loss of biodiversity. Retention forestry has been systematically practiced since 1993 and consists of the preservation of different structures and habitats to create and maintain suitable habitats for species that do not cope well with clear-cutting.

25. Influence of spacing and thinning on wood properties in conifer plantations
Abstract : As reported in four appended papers (I-IV), effects of genotype (half-sib family) and initial spacing (I) or initial spacing (II) and various thinning methods (III & IV) on stands and properties of sawn-products were investigated in Scots pine (I & IV), lodgepole pine (II) and Norway spruce (III) stands in southern Sweden. Most of the analysed growth parameters were found to be affected by interaction between genotype and initial spacing, but the treatments had no significant interactive effects on most quality parameters (I).
