  • 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

Območje zajema vodotok Gradaščico dolvodno od Polhovega Gradca. Dolvodno od jezu pri Bokalcih del voda združene Gradaščice in Horjulščice nadaljuje pot skozi Ljubljano kot Mali graben. To je umetno izkopan razbremenilnik Gradaščice, ki se v Ljubljani na območju Trnovega zliva v Ljubljanico. Reka Ljubljanica je v območje zajeta dolvodno od sotočja z Iščico do izliva v reko Savo.

4.2 Quality and importance

Vodotok je pomemben habitat več vrst rib in Eudontomyzon spp. Unio crassus živi na peščenem in gramoznem dnu Gradaščice. Ljubljanica pri Zalogu je habitat kačjega pastirja Ophiogomphus cecilia.
