Other Site Characteristics

The site consists of two nature reserves near each other. The smaller one is a peninsula in brackish water, dominated by broad-leafed forest, though the main quality is lowland hay meadows. Soils in the area is very lime-rich, which gives a species-rich flora. The flat coast gives, in combination with land uplift, a wide zone of succession with special vegetation. The bigger nature reserve is dominated by mixed forests. The soil is dominated by very lime-rich till. There is also peat in connection with small lakes within the reserve and just outside the boundary. There is also a few small abandoned arable fields.

4.2 Quality and importance

Häverö prästäng nature reserve is one of very few hay meadows in the south-eastern Swedish mainland. There was a period without mowing a few decades in the middle of the century. Since 1960'ies it has been yearly mowed and it is still in a phase of expanding restoration. The meadows have a well developed meadow vegetation on alkaline soils. It has for exempla a rich orchid flora. The reserve is also the only locality in Sweden for the ascomycet Discina caroliniana and there is also an extremely rare insect who's name I have not been able to find in this short time. It's host herb is Inula, growing near the shore line. There is also a rich flora on seashore meadows, as well as in broad-leafed forest stands. On old deciduous trees in open stands there are an species-rich flora of epiphytic lichens with some threatened species. The site has also shown to have an extremely species-rich mykorrhiza fungus flora, with several rare species. Several of the rare species as well as a rich fungus flora as such is supposed to be favoured by outfield grazing. Also this nature reserve has its extremely rare insect, Scleropterus seratus. In this case it is one of two localities on the Swedish mainland. Both are nature reserves with Cypripedium, though the insect is said to live on Geum rivale which is very common in all of Sweden. The figure after the species in the Sweden species-table indicates the category in the national red data list. Buxbaumia viridis - three localities.
