[hr]U travnju i rujnu 2023. godine tvrtka Geonatura d. o. o. provela je pra\u0107enje populacija \u0161i\u0161mi\u0161a u vrijeme sezonskih migracija na \u0161irem podru\u010dju \u201eNP Krka\u201c u podzemnim skloni\u0161tima Miljacka II, Velika pe\u0107ina Kao\u010dinka i Topla pe\u0107ina, \u010cikola<\/strong><\/p>\n

Provedene aktivnosti bile su nastavak vi\u0161egodi\u0161njih istra\u017eivanja i pra\u0107enja \u0161i\u0161mi\u0161a na \u0161irem podru\u010dju Parka i njegove okolice. Terenska istra\u017eivanja provedena su u skladu sa smjernicama me\u0111unarodnog Sporazuma o za\u0161titi europskih populacija \u0161i\u0161mi\u0161a (UNEPEUROBATS) i nacionalnim programom pra\u0107enja stanja \u0161i\u0161mi\u0161a na podru\u010dju Republike Hrvatske. Istra\u017eivanje je provedeno s ciljem prikupljanja podataka o populacijama \u0161i\u0161mi\u0161a koje obitavaju u navedenim skloni\u0161tima u razdoblju sezonskih migracija, o njihovoj brojnosti i sastavu vrsta. Na temelju terenskih opa\u017eanja, analizirane su i mogu\u0107e prijetnje skloni\u0161tima i dane preporuke za daljnje aktivnosti.<\/p>\n

Zabilje\u017eeno je ukupno osam vrsta \u0161i\u0161mi\u0161a: Rhinolophus blasii<\/em> (Blazijev potkovnjak), R. euryale<\/em> (ju\u017eni potkovnjak), R. ferrumequinum<\/em> (veliki potkovnjak), Myotis blythii<\/em> (o\u0161trouhi \u0161i\u0161mi\u0161), M. emarginatus<\/em> (ri\u0111i \u0161i\u0161mi\u0161), M. capaccinii<\/em> (dugonogi \u0161i\u0161mi\u0161), Eptesicus serotinus<\/em> (kasni no\u0107njak) i Miniopterus schreibersii<\/em> (dugokrili pr\u0161njak). Sve zabilje\u017eene vrste, osim vrste Eptesicus serotinus<\/em> (kasni no\u0107njak), uklju\u010dene su u Dodatak II Direktive o stani\u0161tima, odnosno u Popis biljnih i \u017eivotinjskih vrsta od zna\u010daja za Europsku uniju koje zahtijevaju za\u0161titu.<\/p>\n

Velika pe\u0107ina Kao\u010dinka prvenstveno ima ulogu tranzicijskog skloni\u0161ta. Njezino zna\u010denje prvi put je potvr\u0111eno u okviru ovog projekta kada su u istra\u017eivanju u rujnu 2023. u njoj zabilje\u017eene ve\u0107e kolonije vrsta R. euryale<\/em> i R. ferrumequinum<\/em>. \u0160pilja Miljacka II ujedno je i va\u017eno ljetno skloni\u0161te, a Topla pe\u0107ina je u istra\u017eivanjima provedenim 2023. tako\u0111er prepoznata kao va\u017eno tranzicijsko skloni\u0161te, ali joj status ljetnog skloni\u0161ta treba potvrditi daljnje pra\u0107enje. Zbog malog broja istra\u017eivanja i \u010desto upitne pouzdanosti podataka dobivenih njima, do drugih spoznaja o tim \u0161i\u0161mi\u0161ima nije mogu\u0107e do\u0107i, pa treba i dalje redovito pratiti stanje populacija \u0161i\u0161mi\u0161a u sezonskim migracijama.<\/p>\n

\nMonitoring bat populations during seasonal migrations<\/strong>
\nIn April and May 2023, the company Geonatura d.o.o. conducted monitoring of the bat population during the seasonal migration period throughout the area of Krka National Park, in the underground shelters Miljacka II, Velika pe\u0107ina Kao\u010dinka cave and Topla pe\u0107ina cave, \u010cikola River<\/strong><\/p>\n

These activities were the continuation of multi-year research and monitoring of bats in the park territory and its surroundings. The field research was performed in accordance with the guidelines of the International Convention to Protect European Bat Populations (UNEPEUROBATS) and the national bat monitoring programme in the Republic of Croatia. The research was aimed at collecting data on bat populations that inhabit these shelters during the period of the seasonal migrations, and data on the species composition and their abundance. Based on the field observations, possible threats to shelters were analysed and recommendations given for further activities.<\/p>\n

A total of eight bat species was recorded: Rhinolophus blasii<\/em> (Blasius\u2019 horseshoe bat), R. euryale<\/em> (Mediterranean horseshoe bat), R. ferrumequinum<\/em> (greater horseshoe bat), Myotis blythii<\/em> (lesser mouse-eared bat), M. emarginatus<\/em> (Geoffrey\u2019s bat), M. capaccinii<\/em> (long-fingered bat), Eptesicus serotinus<\/em> (serotine bat) and Miniopterus schreibersii<\/em> (common bent-wing bat). All the recorded species, with the exception of Eptesicus serotinus<\/em> (serotine bat), are included in Annex II of the Habitat Directives, i.e., the List of plant and animal species of significant to the European Union and requiring protection.<\/p>\n

The Velika pe\u0107ina Kao\u010dinka cave primarily serves as a transitional shelter. Its importance was observed for the first time as part of this study, when larger colonies of R. euryale<\/em> and R. ferrumequinum <\/em>were recorded during field surveys in September 2023. The Miljacka II cave is also an important summer shelter, while the Topla pe\u0107ina cave was also found to be an important transitional shelter during research in 2023, though confirming its status as a summer shelter requires further monitoring. Due to the small number of surveys and the often-questionable reliability of data obtained, it was not possible to learn more about these bats, and so regular monitoring of the state of populations of these bats during the seasonal migrations is necessary.<\/p>\n
