Atmospheric deposition to forests has been monitored in the frame of the ICP Forests programme with sampling and analyses of bulk and throughfall deposition at several hundred forested Level II plots for more than 15 years now. Current deposition of inorganic nitrogen and sulphate is highest in Northern Central Europe as well as in some regions in southern parts. In this study we compared linear regression and MannKendall trend analyses techniques. The choice of method had an influence on the number of trends identified as being significant. We showed that the minimal detectable trends can be estimated with the mean short term temporal variability of the deposition, which is to a large extent due to meteorological variations, such as the precipitation and circulation patterns. The overall decreasing trends for inorganic N and SO42- in the past decade of about 3% and 6% require time series of about 10 and 6 years respectively to detect a trend on a plot with statistical significance. Past reduction of human emission reduced atmospheric deposition of acidifying and eutrophying compounds. This could be confirmed due to the availability of long-term data series. However, further reductions are required to reduce deposition to forests below critical loads for the whole of Europe.

Environmentalists tell us that we’re loosing species at an increasing rate, and if we are to stop the cascading extinctions by 2020 (which we have agreed upon in international conventions) we need to take immediate action. Making sure we’re not loosing any ’native’ species may seem a daunting task, especially if we look at insects, spiders, fungi, and other tiny creatures that live in dead wood. For thousands of these saproxylic species the wood and timber that we are harvesting make up the bread and butter of their everyday life. The competition is fierce, and it doesn’t get any better when we remove most of the wood that otherwise would have become their future homes. What shall we do?

Tourism is acknowledged to be an important business sector in rural areas. This paper argues that second-home owners constitute an important market segment for businesses that offer nature-based tourism activities. Previous research has shown that a number of factors influence tourist behaviour. This study examined how motivation and demographic variables affect second-home owners\" intention to purchase three different types of activity products: learning, adventure, and hunting products. We found substantial variations in the purchase intentions for these products among second-home owners. These intentions were influenced by push and pull motivations, age, income and educational level. Second-home owners with a high intention of purchasing nature-based tourism activity products tend to be young, high-income, and socially oriented risk takers. Businesses offering nature-based tourism activity products should use a combination of demographic and psychographic variables when they segment the second-home market. Highlights The second-home market is important for nature-based tourism businesses. Their intention to purchase such products are influenced by leisure motives and demographic variables. Recreation experience preferences and reasons for having a second-home in an area influence their purchase intentions. Age and education level have a negative effect on the intention to purchase. Income has a positive effect on the intention to purchase.

This study evaluates the effects of climate change on agriculture in Northern Norway. It is based on downscaled climate projections for six different municipalities combined with interviews with farmers, advisors and administrative personnel in these municipalities. The projections document large climatic differences both between and within the different municipalities. The main predicted climatic changes include increasing temperatures and precipitation as well as increased frequency of certain types of extreme weather events. Despite challenges such as unstable winters, increased autumn precipitation and possibly more weeds and diseases, a prolongation of the current short growth season together with higher growth temperatures can give new opportunities for agriculture here. The impacts are expected to differ both within and between municipalities and will require tailored adaptive strategies. Most of these however should pose no difficulty implementing, having an agronomical basis that farmers are accustomed to cope with.
