European distribution of D.plantarius (Clerk)
How you can help
Most historical records of D.plantarius are difficult or impossible to verify because of the frequent taxonomic confusion with the congeneric species Dolomedes fimbriatus . In addition, the cryptic nature of D.plantarius , combined with the difficulty of locating it amongst emergent aquatic vegetation, makes the recording and the assessment of its range very difficult.
THE CURRENT DISTRIBUTION
The distribution map has been prepared using different sources, including published literature references, web sites, and personal communication. These are acknowledged in the map legend (for original sources refer to the list of references). It is important to note that this map is not a verified indicator of the D. plantarius distribution - it is given as a guide. The map is not to scale.

THE STATE OF THE POPULATIONS
Although the D. plantarius has almost certainly been underrecorded, there is also no doubt that its populations have declined throughout its range, as a result of the degradation and loss of its lowland aquatic habitat. This has prompted many countries to red list this species.
