• While correlations between the SGI and environmental parameters were stronger before the Nickel smelter began operation in 1946 than after, there were still no significant relationships between interannual growth patterns and environmental conditions • Multivariate analysis of mineral ratios suggests a difference between preand post-1946 samples at one site • Preliminary results from fresh water pearl mussels collected from the Karpelva River do not reveal a strong sclerochronological proxy for environmental conditions even in the absence of pollution. • Shell mineralogy holds promise as a very long-term record of heavy metal concentrations in the environment

Abstract
Use of harvest residues for bioenergy is minimal in Norway, and the proposed increase of 14 TWh in annual bioenergy use by year 2020 may thus to a large part be based on residues from conventional timber harvesting. To judge the potential of harvest residues for bioenergy both in the short and long run, we present cost-supply curves for residue harvesting at national and regional levels. We produce different harvesting scenarios using the detailed forest model Gaya/J and a representative description of the Norwegian forest area from Norwegian national forest inventory (NFI) sample plots including environmental restrictions. Forest information is sufficiently detailed to estimate necessary biomass fractions and calculate costs of harvest residue extraction at plot level. We estimate a maximum annual energy production of 5.3 TWh from harvest residues with the present harvest level, which is far from the official target. In principle, there are two solutions for achieving this target; increase harvests and thus the corresponding residue supply, or increase the use of roundwood for energy purposes on the expense of pulpwood. Scenarios with long-run increase in timber production shows an annual energy potential from harvest residues in the range 6–9 TWh. Thus, to reach the political target roundwood must be used for energy production.

Four chapters follow in this book: Background, Challenges, Foresight, and Conclusion – What’s Next. The first chapter, Background, takes stock of land monitoring practices in European countries. The second chapter, Challenges, relates a range of issues encountered with land monitoring as it is currently practised and how such matters can be better resolved through improved collaboration. Building upon these findings, the third chapter, Foresight, outlines the HELM (Harmonised European Land Monitoring) roadmap towards a mature, integrated pan-European land monitoring system based upon aggregated national data which are supplemented by centrally produced base data. The concluding chapter, What’s Next, sets the HELM project and its recommendations in context.
