- 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)

- S: in case that the data on species are sensitive and therefore have to be blocked for any public access enter: yes
- NP: in case that a species is no longer present in the site enter: x (optional)
- Type: p = permanent, r = reproducing, c = concentration, w = wintering (for plant and non-migratory species use permanent)
- Unit: i = individuals, p = pairs or other units according to the Standard list of population units and codes in accordance with Article 12 and 17 reporting (see reference portal)
- Abundance categories (Cat.): C = common, R = rare, V = very rare, P = present - to fill if data are deficient (DD) or in addition to population size information
- 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); VP = 'Very poor' (use this category only, if not even a rough estimation of the population size can be made, in this case the fields for population size can remain empty, but the field "Abundance categories" has to be filled in)

4.2 Quality and importance
| Bjurälven´s Nature Reserve. Sweden´s most distinctive karst land.
The river Bjurälven runs through a 3 km long area of limestone bed-rock. The carbonic acid of the water in contact with the lime in the bed-rock has formed the nature at Bjurälven. Such an area is known as karst land. In Blinda Dalen (Blind valley) the river plays hide-and-seek. It disappears into a sinkhole leaving the riverbed dry. Some kilometers downstream the water bubbles up from underground into siphons, as in the lake Dolinsjön.
Korallgrottans Nature Reserve. Swedens longest cave.
1985 became a fateful year for Lummelunda-grottan on the island of Gotland. Thats when Korallgrottan (The Coral cave) was discovered west of Ankarvattnet.
After laborious crawling, investigating and measuring, the conclusion has been reached that the total length of Korallgrottans paths and rooms adds up to almost 5 kms. That makes it Swedens longest cave, at least up to present time. The cave was formed in the same way as Bjurälvens karst land. The large main
tunnel, which is about 5 meters high and 3 meters wide, was already in existence when the last ice age began approximately 115,000 years ago. Some of the caves stalagtites resemble coral, which has also given the cave its name. Accompanied by your cave guides even you of can take part in this exciting and unforget-
able experience of crawling through narrow passages and viewing the fantastic
rooms. Well worth every crown it costs! The price includes the guided tour, pro-
tective clothing and head lamps. Dont forget to bring a packed lunch. It will
definitely taste good after your adventures in the cave. The entrance to the Korall-cave is hidden by an impressive cliff-overhang. When the inland ice melted some 9,000 years ago, the melting water carried with it soil and stones which plugged up the lower part of the main tunnel. The water then had to find new outlets and a system labyrinths was formed. In some areas of the now dry tunnels, water has forced its way through cracks in the ceilling. Very slow-growing stalagtites are formed there. Most of them are shorter than 10 cms., and it has taken them perhaps 8,000 years to grow those few centimeters. Some of the caves stalagtites resemble coral, which has also given the cave its name.
Accompanied by your cave guides even you of can take part in this exciting and unforgetable experience of crawling through narrow passages and viewing the fantastic rooms. Well worth every crown it costs! The price includes the guided tour, protective clothing and head lamps. Dont forget to bring a packed lunch. It will definitely taste good after your adventures in the cave. |
