  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)

Other Site Characteristics

Örbacken nature reserve is situated north of a large geological delta formation that was created at the end of last glacial period. The reserve is surrounded by forests and open arable fields. The petrifying spring has tufa-formations in the center and the flora is rich especially around the spring. The mollusc-fauna of the area is of interest.

4.2 Quality and importance

The petrifying spring with tufa-formation and the surrounding habitats are of big interest. Nowadays only a few of the springs remain in the open farming land (drainage/agriculture have reduced the number a lot). The spring-area is kept open with extensive grazing and bushes are taken away. Örbacken is very important as a habitat to lime-molluscs and flora.

No

6.3 Conservation measures (optional)

The main purpose of the Örbacken nature reserve is to protect the petrifying spring. It is also important to maintain the pasture land lying in connection to the spring. The forest included in the reserve should not be managed at all with the purpose of creating a lot of dead wood etc. For management plan, see binder 86-202 (see 4.6)
