U tu svrhu provedeni su opse\u017eni terenski radovi i analizirani njihovi rezultati. Metodolo\u0161ki pristup utvr\u0111ivanju stanja i mjera koje treba poduzeti obuhva\u0107a utvr\u0111ivanje elemenata strukture i funkcije stani\u0161nog tipa na transektima polo\u017eenima na odgovaraju\u0107im lokalitetima.<\/p>\n
Na svakom od transekata utvr\u0111eni su elementi strukture stani\u0161nog tipa: sastav i udjel tipi\u010dnih nepovoljnih i standardnih (uobi\u010dajenih) vrsta za taj stani\u0161ni tip, a povr\u0161ina obuhvata (\u0161ire podru\u010dje transekta) relevantna je za procjenjivanje elemenata funkcija stani\u0161nog tipa (zastupljenost mrtvih stabala i intenzitet stresnih \u010dinilaca). Pored toga, utvr\u0111en je stupanj prisutnosti i utjecaja abioti\u010dkih (poplava, po\u017eara) i bioti\u010dkih (fitogenih, zoogenih i antropogenih) \u010dinilaca, posebice ako predstavljaju prijetnju o\u010duvanju stani\u0161nog tipa u povoljnom stanju. Svi ti parametri analizirani su u kona\u010dnoj ocjeni stanja o\u010duvanosti stani\u0161nog tipa, prepoznavanju pritisaka i preporuci mjera za\u0161tite koje je potrebno poduzeti da bi se o\u010duvao u povoljnom stanju.<\/p>\n
Stani\u0161ni tip 91F0 obuhva\u0107a vla\u017ene, povremeno poplavne \u0161ume u kojima prevladavaju higrofiti, a od drve\u0107a su klju\u010dne vrste poljski jasen, nizinski brijest, crna joha i bijela vrba. U NP \u201eKrka\u201c rasprostire se uglavnom u obalnom podru\u010dju i na terasama uz rijeke Krku i \u010cikolu, a povr\u0161ina mu iznosi 63,87 ha. Najzna\u010dajniji lokaliteti rasprostiranja jesu Skradinski buk, Manastir Krka, Miljacka mlin i Bilu\u0161i\u0107a buk uz rijeku Krku i Klju\u010dica uz rijeku \u010cikolu.<\/p>\n
Stani\u0161ni tip 9340 obuhva\u0107a \u0161ume hrasta crnike s mediteranskim vrstama, od koji su, uz hrast crniku, posebice va\u017ene zelenika (Phillyrea<\/em> sp.), crni jasen, grmoliki gra\u0161ar, tr\u0161lja, tetivika i druge. Tip 9340 rasprostire se na podru\u010dju Ma\u010dkovice, a povr\u0161ina mu iznosi 17,25 ha.<\/p>\n Na \u010detirima lokalitetima stani\u0161nog tipa 91F0 (Skradinskom buku, Manastiru Krka, Miljacka mlinu i Bilu\u0161i\u0107a buku) utvr\u0111eno je njegovo dobro stanje. Povr\u0161ina stani\u0161nog tipa u dobrom stanju iznosi 51,32 ha. Ocjena se bazira prije svega na udjelu i pokrovnosti vrsta tipi\u010dnih za taj stani\u0161ni, tip me\u0111u kojima su posebice va\u017ene Fraxinsus angustifolia<\/em>, Alnus glutinosa<\/em>, Ulmus minor<\/em>, Salix alba<\/em> i, u grmlju, Cornus sanguinea<\/em> i Crataegus monogyna<\/em>, dok je rijedak Humulus lupulus<\/em>. U prizemnom sloju to su Aristolochia rotunda<\/em>, Lysimachia nummularia<\/em> i Berula<\/em> erecta<\/em>, dok su ostali higrofiti rje\u0111i. Relativno je ve\u0107i broj vrsta iz okolnih su\u0161ih \u0161umskih stani\u0161ta mediteranskog podru\u010dja koje se spu\u0161taju do samog rije\u010dnog korita. To je uobi\u010dajeno ponajprije zbog fitoklimata i biljnih vrsta koje podnose uvjete su\u0161e u ve\u0107em dijelu godine. U dijelu lokaliteta prisutne su strane invazivne vrste, koje u trenutnoj fazi nisu ve\u0107a prijetnja za njegovu opstojnost, no sigurno je da \u0107e se njihova brojnost i pokrovnost u budu\u0107nosti pove\u0107ati. Suho mrtvo drvo uglavnom je umjereno do obilno prisutno. Va\u017ean \u010dinilac u opstanku ovoga tipa u NP \u201eKrka\u201c jest \u010dinjenica da je u hidrolo\u0161koj postaji na Skradinskom buku zabilje\u017een povoljan trend razine voda u posljednjih tridesetak godina. Na lokalitetu Skradinski buk vrlo je zna\u010dajan utjecaj posjetitelja, a na lokalitetu Manastir Krka doma\u0107ih \u017eivotinja.<\/p>\n Na lokalitetu Klju\u010dica (\u010cikola) stanje stani\u0161nog tipa ocijenjeno je kao lo\u0161e (12,55 ha). Razlog je prije svega u slaboj zastupljenosti jasena i velikom su\u0161enju brijesta koje je dovelo do za\u0161ikarenosti stani\u0161ta, izostanku pomla\u0111ivanja tipi\u010dnih vrsta i prisustvu nepovoljnih stranih vrsta te zakorovljenju dijela lokaliteta problemati\u010dnim zavi\u010dajnim vrstama.<\/p>\n Stanje stani\u0161nog tipa 9340 na lokalitetu Ma\u010dkovica je dobro. Ve\u0107i broj tipi\u010dnih vrsta, posebice Quercus ilex, Fraxinus ornus, Phillyrea latifolia, Pistacia lentiscus, Coronilla emerus ssp. emeroides<\/em>, Smilax aspera<\/em> i druge prisutne su gotovo na svim transektima i podru\u010dju lokaliteta. Invazivne vrste koje bi ugro\u017eavale tip nisu prisutne. Mrtvo drvo je umjereno i u zadovoljavaju\u0107em obujmu prisutno na cijelom lokalitetu.<\/p>\n <\/p>\n [\/hr]<\/p>\n [en] For this purpose, extensive field surveys were performed and their results analysed. The methodological approach to establishing the state and measures to be take encompassed determining the structural and functional elements of the habitat type at transects laid at appropriate locations.<\/p>\n On each transect, the structural elements of the habitat type were determined: composition and share of typical, undesirable and standard (common) species for that habitat type, while the area of the survey (width of the transect) is relevant for assessing the functional elements of the habitat type (presence and abundance of dead trees and intensity of stressors). Additionally, the degree of presence and influence of abiotic (flood, fire) and biotic (phytogenic, zoogenic, anthropogenic) factors was determined, particularly if they pose a threat to the conservation of the habitat type in a favourable state. All these parameters were analysed to give the final assessment of the conservation status of the habitat type, to identify the pressures in place, and to recommend protection measures to be taken to preserve the habitat in a favourable state.<\/p>\n The habitat type 91F0 includes wet, occasionally flooded forests dominated by hygrophyte (water-loving) species, and the key tree species are narrow-leaved ash, field elm, black alder and white willow. In Krka National Park, this habitat type is distributed predominantly in the riparian zone and on the terraces along the Krka and \u010cikola Rivers, covering an area of 63.78 hectares. The most significant localities are Skradinski buk, Krka monastery, Miljacka mill, and Bilu\u0161i\u0107a buk along the Krka River, and Klju\u010dica along the \u010cikola River.<\/p>\n Habitat type 9340 includes holm oak forests with Mediterranean species, which in addition to holm oak are particularly privets (Phillyrea<\/em> sp.), manna ash, scorpion senna, mastic tree, smilax and others. Type 9340 is distributed in the area of Ma\u010dkovica, covering an area of 17.25 ha.<\/p>\n At four localities of the habitat type 91F0 (Skradinski buk, Krka monastery, Miljacka mill, and Bilu\u0161i\u0107a buk) it was found to be in good condition. The area of this habitat type in good condition is 51.32 ha. This assessment is based above all on the share and cover of species typical for this habitat type, including the particularly important species Fraxinus angustifolia<\/em>, Alnus glutinosa<\/em>, Ulmus minor<\/em>, Salix alba<\/em> and, in the shrub layer, Cornus sanguinea<\/em> and Crataegus monogyna<\/em>, while Humulus lupulus<\/em> is rare. In the ground layer, these are Aristolochia rotunda<\/em>, Lysimachia nummularia<\/em> and Berula<\/em> erecta<\/em>, while other hydrophytes are rarer. A relatively large number of species from the surrounding dry forest habitats in the Mediterranean area are found all the way down to the river. This is due above all to the phytoclimate and the plant species that tolerate dry conditions throughout most of the year. In parts of the localities, there are invasive alien species that are currently not a threat to the survival of the habitat type, though their abundance and cover are certain to increase in the future. Dry dead wood is present in moderate to high amounts. An important factor for the survival of this habitat type in Krka National Park is the fact that a favourable trend of ground water has been recorded at the hydrology station at Skradinski buk over the past 30 years. At the locality Skradinski buk, the impact of visitors is highly significant, while at the locality Krka monastery, domesticated animals have a strong impact.<\/p>\n At the locality Klju\u010dica (\u010cikola River) the state of the habitat type is assessed as very poor (12.55 ha). The reason for this is primarily the weak presence of ash and the widespread drying of elm, which has led to a more thicket-like appearance of the habitat, with the lack of regeneration of typical species, and the presence of unfavourable alien species with part of the locality covered in problematic native though ruderal species.<\/p>\n The state of habitat type 9340 at the locality Ma\u010dkovica is good. Many of the typical species are present in nearly all transects and areas of the locality, particularly Quercus ilex, Fraxinus ornus, Phillyrea latifolia, Pistacia lentiscus, Coronilla emerus ssp. emeroides<\/em>, Smilax aspera<\/em> and others. There are no invasive species that would pose a threat to the habitat type. Dead wood is present in a moderate and satisfactory ratio throughout the entire locality.<\/p>\n <\/p>\n In 2023, the company Prosilva d.o.o. performed research in the territory of Krka National park to determine the state of two Natura 2000 habitat types: 91F0 \u2013 flooded mixed forests of Quercus robur, Ulmus leavis, Ulmus minor, Fraxinus angustifolia, and 9340 \u2013 evergreen holm oak forests (Quercus ilex), and the measures required for their conservation<\/p>","protected":false},"author":2,"featured_media":9586,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[45],"tags":[],"class_list":["post-9580","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-monitoring"],"_links":{"self":[{"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/posts\/9580","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/comments?post=9580"}],"version-history":[{"count":4,"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/posts\/9580\/revisions"}],"predecessor-version":[{"id":14057,"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/posts\/9580\/revisions\/14057"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/media\/9586"}],"wp:attachment":[{"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/media?parent=9580"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/categories?post=9580"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/npkrka.hr\/en_us\/wp-json\/wp\/v2\/tags?post=9580"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![](\"https:\/\/npkrka.hr\/wp-content\/uploads\/20230619_163650.jpg\")
