Istraživanje geomorfoloških značajki područja Oštarije-Tounj (Hrvatska) u svrhu zaštite krša tog područja

Područje Oštarije-Tounj nalazi se između Ogulinsko-plaščanske zavale (tj. krške depresije) i prostrane Unsko-koranske zaravni. Odlikuje se brojnim krškim fenomenima, a posebno špiljama. Špilja u kamenolomu Tounj (ŠukT) i špilja Tounjčica nalaze se u području brda Krpel nedaleko naselja Tounj. One za sada nisu fizički spojene, ali predstavljaju jedinstven hidrografsko-morfogenetski sustav krških provodnika. Obje špilje, a posebno ŠukT ozbiljno su ugrožene radom kamenoloma u Tounju te je JU za upravljanje zaštićenim prirodnim vrijednostima Karlovačke županije pokrenula projekt „Trajna zaštita Špilje u kamenolomu Tounj“. U okviru tog projekta izrađena je studija „Geomorfološka obilježja Špilje u kamenolomu Tounj i špilje Tounjčice s okolnim područjem“ kako bi se utvrdile osnovne geomorfološke i morfogenetske značajke ovih špilja, ali i čitavog područja s kojima špilje čine jedinstvenu i nedjeljivu cjelinu. Utvrđeni su osnovni uvjeti i čimbenici razvoja reljefa, morfostrukturne značajke reljefa te egzogeni krški i fluviokrški procesi i oblici. Posebno su obrađene geomorfološke značajke ŠukT i špilje Tounjčice. U okviru istraživanja je izrađena geomorfološka karta mjerila 1:25000. Utvrđena je izuzetna georaznolikost krških površinskih i podzemnih oblika ovog područja, ali i njihova velika ugroženost. Zbog navedenih vrijednosti i njihove ugroze predlaže se trajna zaštita obje špilje s odgovarajućom površinom nadsloja u kategoriju geomorfološki spomenik prirode. Također se zbog sigurnosti predlaže privremena sanacija ulaznog dijela špilje. Oštarije-Tounj area is situated between Ogulin-Plaški large karst depression and wide Una-Korana karst plateau. It is characterized by numerous karst phenomena especially caves. Cave in Tounj quarry (ŠukT) and cave Tounjčica are located in Krpel hill area near Tounj settlement. They are not physically connected (in speleological sense) but they are unique hydrographic-morphological system of the underground karst conduits. Both caves, especially ŠukT, are very threatened by quarry exploatation. Public institution for managing with protected natural values of the Karlovac county started with project “Permanent protection of the Cave in Tounj quarry” within a framework study “Geomorphological characteristics of the Cave in Tounj quarry and cave Tounjčica with surrounded area” was made. The main goal was determination of the basic geomorphologic and morphogenetic features of this caves and surrounded area because it is unique and indivisible karst complex. The basic conditions and factors of the landscape development, morphostructural characteristics and exogenous karst and fluviokarst processes and forms settled. Special attention is taken to geomorphology of these caves. Within a framework of this work geomorphological map in scale 1:25000 was made. It is concluded that this area have a high geodiversity of the karst surface and underground forms but there is high vulnerability and threats of this karst complex. According to these conclusions it is recommended to declare this site as permanent protected area in the category of the geomorphological nature monument. Also, restoration of the destructed entrance part of the cave is proposed.
