Cyperus fuscus was rediscovered at Lake Vombsjön in Skåne, southernmost
Sweden, in 2013. The species occurred there between 1945 and 1950, which was the latest Swedish record except for a casual occurrence in a plant nursery. The comeback was spectacular with 2770 individuals counted along 4.7 km of the shore. In 2013, the water level was exceptionally low for technical reasons,
with up to 100 m of the sandy shore exposed during the entire vegetation period, i.e. the same
conditions as during the late 1940’s. Later, the lake became an important source of drinking water, and the regulated maximum water level was increased with more than one metro. The coming years will show whether the species regularly occurs at low frequency at the lake, or if it is dependent on rare years with low water to survive.
