Development and implementation of the Norwegian monitoring programme for agricultural landscapes.
The importance of establishing a baseline to enable the detection of development trends in a rapidly changing environment is stressed and the accuracy of the methods employed and the range of indicator values recorded in the Norwegian monitoring programme are presented.
Gains to species diversity in organically farmed fields are not propagated at the farm level.
Gains to species richness are partly caused by higher organism abundance and are common in plants and bees but intermittent in earthworms and spiders, and additional, targeted measures are needed to fulfil the commitment of organic farming to benefit farmland biodiversity.
The landscape ecology of butterflies in traditionally managed Norwegian farmland
The modernisation of agriculture has lead to changes in Norwegian farming landscapes that have consequences for butterfly distribution and abundance. Particularly important is the abandonment of
Scale-dependent importance of environment, land use and landscape structure for species richness and composition of SE Norwegian modern agricultural landscapes
Knowledge of variation in vascular plant species richness and species composition in modern agricultural landscapes is important for appropriate biodiversity management. From species lists for 2201
Genetic diversity of natural orchardgrass (Dactylis glomerata L.) populations in three regions in Europe
All three case study regions revealed high genetic variability of tetraploid D. glomerata within selected populations and numerous rare and localized alleles which were geographically unique.
