Denne rapporten gir en vurdering av hvorvidt praktiseringen av Forskrift om tilskudd til forebyggende tiltak mot rovviltskader og konfliktdempende tiltak (FKT-forskriften) har god måloppnåelse, om den kan realiseres på en bedre måte enn i dag og i så fall hvordan. Arbeidet bygger på litteratur- og dokumentstudier samt intervjuer av representanter for beitenæringene og landbruks- og miljøforvaltningen. Oppdraget omfatter a) en utredning av hvordan FKT-ordningen er organisert, hvilke tiltak som har mottatt støtte og omfanget av støtten som er gitt, b) en vurdering av effekten av forebyggende tiltak, effekten av tiltak som kan øke kunnskapsgrunnlaget og effekten av konfliktdempende tiltak og c) en beskrivelse og drøfting av forslag til tiltak og forskriftsendringer som kan gi forbedret måloppnåelse for FKT-forskriften samt en samfunnsøkonomisk vurdering av disse.

This article focus is on the perceived impact that aquaculture industry has on coastal communities in Northern Norway. Here, aquaculture is key industry with natural, social and economic impacts. In natural resource management in general, identifying and monitoring the perceived social impacts can be a useful tool for local planning. In order to ensure the blue growth goals of the Norwegian government and avoid conflict and mistrust in the future, it is important to understand how both the general public and stakeholders perceive the aquaculture industry, how it affects them and its use of space in the coastal zone. Hence, we ask a) how do coastal communities perceive the aquaculture industry and b) is there a legitimacy gap between the blue growth strategies of the Norwegian Government and the public? In order to answer these questions, we lean on theories related to legitimacy and stakeholder's participation. Original data were collected from structured (N = 150) and semi-structured interviews (N = 10) in two coastal communities in Northern Norway (Alstahaug and Brønnøy). Our findings suggest that a legitimacy gap does exist between blue growth goals and fishers in the communities studied, while the general citizen holds a positive attitude towards aquaculture. Insights from this study are useful for local, regional and national decision makers with responsibility for natural resource policies and development efforts.

Understanding the factors that determine species’ resistance to environmental change is of utmost importance for biodiversity conservation. Here we investigated how the abundances of marshland species are determined by niche properties and functional traits. We re-surveyed 150 vegetation plots that were first surveyed in 1973 in order to explore species abundance changes over time. We found that the mean water level in the habitats of most studied species decreased significantly from 1973 to 2012. Nine of 17 target species were identified as abundance decreasing species and the other eight as abundance increasing species. The comparisons of seven plant characteristics (niche position water level, plant height, and five leaf traits) showed that the decreasing species had a significantly higher value of optimum water level and marginally significantly lower leaf N contents and specific leaf area (SLA) than those in increasing species. The stepwise regression analysis showed that optimum water level and leaf N were the best predictors of abundance changes of marsh plant species, as well as that the effect of optimum water level was stronger than that of leaf N. Our findings demonstrated that niche properties may be important for forecasting changes in wetland plant communities over time.

Questions Have species richness and composition in subarctic vegetation changed over the past ca. 90 years? Are compositional shifts linked to changes in land management or climate? Are observed changes associated with vegetation type, life form, or habitat preference? Location Rybachy and Sredny Peninsulas, NW Russia. Methods We resurveyed vegetation ca. 90 years after the first sampling in 1927–1930 to study changes in species richness, abundance and composition. Because of missing plot‐related environmental measurements we used a weighted averaging approach calculating relative changes in species‐specific optimum values for different environmental gradients represented by species indicator values to identify compositional change in relation to the environment. Changes in species composition were visualised using detrended correspondence analyses. Significances of observed changes in species richness and frequency were evaluated using restricted permutation tests. A χ2 test was used to test if observed changes in abundances were related to species’ life form and habitat preferences. Results Species composition has changed significantly over the past ca. 90 years, as indicated by significant changes in species’ frequencies and values of optima for the environmental gradients temperature, moisture, nutrients and light. Species richness decreased significantly, in particular in nitrophilous and wet growing vegetation. Species typical for grazed grasslands and meadows and species of wet habitats became less abundant, while dwarf shrubs and forest species increased. Conclusions Land abandonment, in combination with climate change, is likely to have caused the observed changes in the subarctic vegetation of NW Russia. Shifts in the species dominance ratios and interspecific competition (e.g. for reallocated nutrients) after land abandonment may have been promoted by the subsequent change towards a warmer climate, facilitating the regrowth of previously open meadows with grazing‐intolerant tall herbs, forest herbs and dwarf shrubs. This study illustrates clearly the long‐term effects of land‐use change, the consequences of which are still visible even after almost one century in the subarctic.
