In Norway, the reindeer exists as both a wild and semi-domesticated species. The latter forms the basis of a livelihood and industry that is the clearest characteristic of Sámi culture, and it is protected by international law and the Norwegian Constitution. Nevertheless, reindeer herding is threatened by loss of land used for infrastructure and recreation facilities development, as well as human activities in the outfields (utmark). Reindeer are physically vulnerable, and society’s institutions do not provide sufficient protection of land for grazing and herding of reindeer. Politicians and the general public are largely unaware of this. The chapter documents this by analyzing land-use challenges in two reindeer-herding districts. Besides loss of pastureland, the accumulated effect of former losses is a loss of flexibility, which makes adaptation to new challenges increasingly difficult. The authors suggest several practical measures (e.g. plans, maps, etc.), but also point to the need for general education in Sámi culture and affairs, for politicians as well as the public. This should be a part of necessary reconciliation processes in the context of historical assimilation policies. Furthermore, the Norwegian government should strengthen its efforts to realize the intentions of plan and building laws by strengthening local and regional government obligations.

Denne rapporten presenterer rekartlegging og verdisetting av naturtyper, spesielt med hensyn til kystlynghei og strandeng på Svinøya i Nærøysund kommune, Trøndelag fylke, på oppdrag fra Nærøysund kommune. Målsettingen med arbeidet var å få en rekartlegging av kystlyngheien på Svinøya etter NiN, samt en kort, overordnet vurdering av lokalitetene etter DN-håndbok 13.

We compiled data from several independent, long-term silvicultural studies on USDA Forest Service experimental forests across a latitudinal gradient in the northeastern and north-central U.S.A. to evaluate factors influencing aboveground live-tree carbon sequestration and mortality. Data represent five sites with more than 70,000 repeated tree records spanning eight decades, five ecoregions, and a range of stand conditions. We used these data to test the relative influence of factors such as climate, treatment history (uneven-aged or no management), species composition, and stand structural conditions on aboveground live-tree carbon sequestration and mortality in repeatedly measured trees. Relative to no management, we found that uneven-aged management tended to have a positive effect on carbon sequestration at low stocking levels and in areas of favorable climate (expressed as a combination of growing season precipitation and annual growing degree days > 5 ◦C). In addition, losses of carbon from the aboveground live-tree pool due to tree mortality were lower in managed than unmanaged stands. These findings suggest that there may be conditions at which rate of sequestration in living trees is higher in stands managed with uneven-aged silviculture than in unmanaged stands, and that this benefit is greatest where climate is favorable.
