Other Site Characteristics

Ombergsliden is situated on the western slope of the mountain Omberg, which is a geological horst. Omberg was formed for 600 to 200 million years ago by faults in the earth-crust. The bedrock consists of granite. The inland ice transported materials from the neighbouring younger bedrock up on the mountain which resulted in a soil with contents of lime. Approximately 25 alkaline fens are situated on the mountain. The nature reserve is a mosaic of different habitats such as alkaline fen, wet alkaline meadow, dry alkaline meadow, open pasture, taiga forest and mixed forest. The flora is rich with a number of orchids and other species dependent on/or favoured by the lime-content in the area. Also the fauna of insects are of big interest as well as the molluscfauna.

4.2 Quality and importance

Ombergsliden is a very valueable site with very high biological values. The alkaline fens are representative with a very rich flora for example Gymnadenia odoratissima. The molluscfauna is also representative and characteristic with rare species. The dry alkaline meadow is welldeveloped with species dependent on lime and dry conditions. The rare butterfly Hamearis lucina. The site contains several different habitats in a small area which contributes to the high variations and the big number of species living in the site. The geological and hydrological values of Ombergsliden are also very high.

6.3 Conservation measures (optional)

The main purpose of the nature reserve is to protect the alkaline fens with belonging biological values. The other habitats included in the reserve shall be protected as well. The site should be managed with grassing in some parts. Other parts are left without any managing (parts of the forest). Ombergsliden shall be adjusted for visitors with good information and marked paths. The biological values shall not be allowed to be threatened by the visitors. For more information see the management plan i binder 0584-203 at the County Administration Board.
