As the human population grows and its influence on the environment continually increases, sustainability is again on the policy agenda. At the same time there is increasing awareness of the need for more environmentally attuned landscape planning. Nevertheless, researchers have recognized that many research findings are not applied in real life management or practice. We argue that the lack of incorporating ecological knowledge into landscape planning is partly caused by a communication gap between ecologists and planners and designers. In this article we suggest one approach of how this communication gap could be minimized. We link landscape ecological concepts relevant for land use planning to a well-known planning and design concept, the Emerald Necklace. We argue that applying the Emerald Necklace concept in a planning process can have several possible positive contributions. First, it will necessitate thinking on a landscape scale, i.e., putting the focus not only on individual planning project areas, but also on the ways in which these are linked to the surrounding landscape. Further, it will help identify priority areas from an ecological perspective. Finally, it will emphasize the importance of heterogeneity of habitats and connectivity of the blue-green infrastructure during the planning process. In addition, and equally important, the concept provides abundant opportunities for creative design. We hope using the Emerald Necklace will contribute to improved dialogue and understanding between the professions involved in planning processes.

An undesirable property of systematic spatial sampling is that there is no known method allowing unbiased estimation of the uncertainty of statistical estimates from these surveys. A number of alternative variance estimation methods have been tested and reported by various authors. Studies comparing these estimators are inconclusive, partly because the studies compare different sets of estimators. In this paper, three estimators recommended in recent studies are compared using a single test dataset with known properties. The first estimator compared in this study (ST4) is based on post-stratification of the data. The second estimator (V08) is using a predetermined correction factor calculated from the spatial autocorrelation. The third estimator (MB) is a model based prediction calculated using values from the semivariogram. MB and ST4 were both found to be fairly accurate, while V08 consistently underestimated the variance in this study. V08 relies on the assumption that the autocorrelation structure in the dataset can be described using a particular exponential function. The most likely explanation of the weak result for V08 is that this assumption is violated by the empirical data used in the experiment. A better correction factor can be calculated, but the safe approach is to use MB or ST4.

Mountain tourism depends intensively on the quality of the landscape. In recent years, the Norwegian Trekking Association has focused on local food products at their staffed lodges and it uses the slogan “eat the view.” Such a strategy raises the focus on the agricultural use of the land and the quality of the products. Several Norwegian studies were carried out to investigate the quality of different mountain products and connections with vegetation types and grazing behavior. The results show that milk and meat products from animals grazing on alpine rangelands have improved quality compared to “normal” products. A healthier fatty acid composition and a higher content of secondary plant metabolites were characteristic of mountain products. Furthermore, grazing is of the utmost importance for the maintenance of open mountain landscapes and the biodiversity that is dependent on such landscapes. Maintaining traditional grazing systems also secures the preservation of traditional ecological knowledge about utilizing natural resources. Mountain tourism experiences could be improved and enhanced by documenting and telling the unique story of these complex connections between mountain landscapes, biodiversity, agricultural traditions, and local food products.
