Abstract

Razvoj speleoturizma dovodi do potrebe za istraživanjem ljudskog utjecaja na osjetljive špiljske sustave radi zaštite i održivog upravljanja. Gornja Baraćeva špilja jedan je od mnogih speleoloških objekata na području općine Rakovica i turistima je dostupna u razdoblju od kraja svibnja do kraja listopada. U 2019. godini tijekom sezone posjeta provedeno je istraživanje utjecaja posjetitelja na temperaturu zraka u Gornjoj Baraćevoj špilji. Cilj je bio utvrditi odnos između broja posjetitelja i promjena temperature špiljskog zraka. Temperatura je mjerena na šest lokacija unutar špilje. Pet lokacija uz turističku stazu bilježi porast temperature u različitoj mjeri nakon prolaska grupe posjetitelja, a posljednja lokacija ne bilježi promjene jer se nalazi van staze. Na iznos porasta temperature utječe veličina i duljina zadržavanja grupe pa su lokacije gdje posjetitelji samo prolaze bilježile manji porast temperature u odnosu na lokacije gdje se grupe dulje zadržavaju. Izračunato je da jedan posjetitelj u prosjeku povisi temperaturu za 0,019 ºC, a prilikom dolaska najvećih grupa porast temperature ne prelazi iznos od 0,7 ºC. Nagli porast temperature desi se neposredno nakon prolaska grupe. Unutar dva sata temperatura se vrati na približno početnu vrijednost kakva je bila prije dolaska posjetitelja, a vremenski period u noći kada posjetitelja nema dovoljan je da se temperatura u potpunosti stabilizira. Zaključeno je da trenutni režim posjećivanja ne prelazi nosivi kapacitet špilje, stoga dodatne mjere regulacije nisu potrebne.

Abstract (english)

The development of speleotourism brings with it the need to research the impact of visitors on fragile cave systems in order to protect them and establish the sustainable cave management. The Upper Barać's cave is one of the many speological objects within the territory of the Municipality of Rakovica. For tourist visits it is open in period from the end of May to the end of October. The research on how visitors could affect the air temperature in a suggested time period has been made in 2019. The main goal was to establish the relationship between the number of visits and the air temperature changes. Temperature was measured at six spots within the cave. Five of these spots that were located on the tourist trail showed an increase in temperature values right after the visitors have passed near the measuring spots, while the sixth spot showed no temperature increase as tourists never set foot in that area. The size of a group and time the group spent in cave impacted the amount of temperature increase, so locations where they just passed by without staying in place showed less increase than those where groups stayed for a while. It is calculated that one visitor raises the temperature by 0,019 ºC on average, and after the largest tourist groups the increase did not exceed 0,7 ºC. A sudden rise in temperature occurs immediately after the group passes. Within two hours, the temperature returns to almost its initial value, and the night time period without visitors is long enough for the temperature to fully stabilize. It was concluded that the current visiting regime does not exceed the cave capacity, therefore no additional regulatory measures are required.
