Protected habitats are often small, isolated and lack continuity. We studied forest planning at a landscape scale as a method to increase habitat connectivity, and improve conservation values whilst maintaining high levels of forest production. We assessed the financial impacts of landscape planning for the landowners, and present a fee-fund system to solve unequal burdens among them. As case studies, we used three landscapes along a latitudinal gradient in Sweden. The results demonstrate some variation between the landscapes in terms of the total cost for set asides and large differences in terms of the financial impact per landowner. Our conclusion is that forest landscape planning may be a way forward to improve conservation efforts, but given the variation in financial impacts, we propose to combine landscape planning with economic tools for compensation.

Patterns in soil quality: Natural geochemical variability versus anthropogenic impact in soils of Zeeland, The Netherlands / P.F.M. Van Gaans in International journal of geographical information science IJGIS, vol 21 n° 5 (may 2007)

Comparison with the average upper continental crust identified natural regional features, such as a relative enrichment of As, due to a low-lying deltaic environment, and of Cr and Zr, related to a specific heavy mineral association. Identification of diffuse contamination is best achieved by comparison with a local reference. The Zeeland subsoil is shown to have undergone only minor anthropogenic influence and to serve this purpose very well. A topsoil-subsoil comparison revealed anthropogenic enrichments for Cd, Cu, P, Pb, S, Sb, Sn, Zn, and partly for As, while typically 'non-anthropogenic' trace elements like Cs, Ga, La, and Rb were found not to be enriched. Except for P and S, the enriched components show a good correlation with Al2Oi, a proxy for clay mineralogy, and a bivariate topsoil-subsoil comparison is made using a trimmed Reduced Major Axis regression. Two subregions are identified with different associations (Zn, Pb, and Cd, versus As, Cd, Cu, and Sn) of higher-than-average enrichments.
