  1. 6. The introduction of Pinus contorta in Sweden : implications for forest diversity

    Författare :Sofia Bäcklund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : An increasing demand for forest-based products calls for further development and intensification of forest management. The use of non-native tree species in forestry is a common and expanding silvicultural practice worldwide but the effect of non-native trees on native biodiversity and ecosystem functioning is still poorly understood.

  3. 7. Improving boreal forest regeneration in a variable climate

    Författare :Bodil Häggström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Regeneration of boreal forests in Sweden mainly involves planting Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.) seedlings on clear-cut areas, although there is an increasing interest in planting broadleaves and in applying continuous cover forestry (CCF). LÄS MER

  4. 8. Heart rot of spruce and alder in forests of Latvia : impact and possibilities for silvicultural control

    Författare :Natalija Arhipova; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Heart rot causes great decrease in timber quality throughout the world. In the conifer forests of Northern Hemisphere the most significant losses are caused by fungi from the Heterobasidion annosum species complex. LÄS MER

  5. 9. A Methodology for Automation of Mechanized Forest Regeneration

    Författare :Håkan Lideskog; Magnus Karlberg; Dan Bergström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : High quality forest regeneration is typically performed by a combination of site preparation through mounding and deep planting. These operations are performed either by mounders with subsequent manual planting, or by mechanized tree planting devices that creates mounds and, simultaneously, plant seedlings. LÄS MER

  7. 10. Rowing social-ecological systems: morals, culture and resilience

    Författare :Jacob von Heland; Carl Folke; Sverker Sörlin; Paul Sinclair; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; resilience; culture; moral; complex social-ecological systems; southern Madagascar; Planetary Boundaries; naturresurshushållning; Natural Resources Management;

    Sammanfattning : The shift from management and governance of ecosystems to relational complex adaptive social-ecological systems (SES) emphasizes a dynamic and integrated humans-in-nature perspective. Such a shift also needs to investigate how diversity and differences in cultures and morals relate to the existence of SES. LÄS MER
