Speerwaterjuffer in het nauw

The Northern damselfly is a very rare and endangered dragonfly in The Netherlands. Dutch Butterfly Conservation conducted a research in order to list the current preliminary conclusions on the habitat requirements of the species. It appeared that the Northern damselfly is now restricted to 10 populations and has very strict demands on the biotope. It occurs only in mesotrophic and moderately acid groundwater-fed fens. Measures to be taken are briefly discussed.
