State of biodiversity in the Nordic countries

An assessment of progress towards achieving the target of halting biodiversity loss by 2010

The Nordic countries have agreed on a common target to halt the decline in biodiversity by 2010. This report aims at evaluating the 2010-target by presenting indicators that can describe trends in biodiversity in the Nordic countries. Our results comprise the most comprehensive documentation of land use in the Nordic countries to date. The area of important nature types such as mire, grassland and heathland have decreased significantly over the past one to two decades, whereas the area of constructed habitats, including city areas and transport networks, has grown considerably in all of the Nordic countries. Each of these trends in land use will cause biodiversity to decline. Looking into the quality aspect of biodiversity, our results reveal that two-thirds of the quality indicators presented show declines and the remaining one-third show improvements (or steady-state). Overall, our results indicate that biodiversity has declined in the Nordic countries since 1990. In particular, farmland, mire, grassland and heathland habitats show declines in biodiversity, but also the remaining habitats show negative trends. Therefore, based on the findings from this study, we conclude that it is highly unlikely that the target of halting biodiversity loss by 2010 can be achieved by the Nordic countries. Our results should be perceived as a first attempt to make an overall assessment of biodiversity in the Nordic countries. We believe that if further efforts were directed towards scrutinising existing and historic monitoring programmes and data sources, additional indicators could be calculated and hence a better knowledge base would be achieved.

Hide / Show Abstract

As described previously changes in the quantity of biodiversity is measured as changes in the area of different habitat types. For this purpose we needed an applicable classification of Nordic habitats and nature types. A variety of different classification schemes for habitat and nature types exist. For example, Påhlsson (1998) developed a very detailed classification of Nordic vegetation types. National classification systems have also been developed, e.g. the Norwegian vegetation types (Fremstad 1997) and a nature type system (Norwegian Directorate for Nature Management 2007). Furthermore, at the European scale, several habitat type classifications, such as the European Nature Information System (EUNIS) (Davies et al. 2004), the Corine biotope typology (EC 1991), the Corine Land Cover classification (EEA 2002) and the BioHab habitat type classification (Bunce et al. 2005) have been elaborated.
