Fen Ragwort (Jacobaea Paludosa) in Scandinavia

Fen ragwort, Jacobaea paludosa has a very small distribution area in Scandinavia being restricted to Skåne [Scania], the southernmost province of Sweden. It is rather common only in the Kristianstad area along the river Helgeå. The species has been inventoried in the years 1983, 2000 and 2012, and a follow-up of seven selected sites in Kristianstad Vattenrike was performed annually 2000–2024. Both the number of localities and the number of individuals fluctuated considerably throughout the years. Factors affecting the species’ well-being and frequency as well as its threats are evaluated.
