8310  info      1.00 
  • 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)

3.2 Species referred to in Article 4 of Directive 2009/147/EC and listed in Annex II of Directive 92/43/EEC and site evaluation for them

  • 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)

Other Site Characteristics

Site Jasena ponor is situated in southern Croatia near Vrgorac and belongs to the area of continental Dalmatia. It is a part of the karst field Jasena polje which is fertile and cultivated area very significant for the local residents. Similar to larger karst fields on the south-east, Jasena is also facing the difficulties of inadequate water drainage during the season of high precipitation, which causes flooding. The water usually drains through the pit Jasena Ponor. The underground lake of Jasena ponor is situated at a depth of about 180 m. A route of the highway Zagreb – Split – Dubrovnik is constructed through this area.

4.2 Quality and importance

- important site for Congeria kusceri - Jasena ponor represents one of six known living colonies in Croatia, also population of Congeria in Jasena ponor represents most northern finding of Congeria kusceri (more northern populations of Congeria in Croatia, in Lika region, belong to newly described species Congeria jalzici found from only three localities in that region) - important site for Proteus anguinus
