From April 27 till May 5 2012 in Krupac, Sićevo gorge, we were hosts to biology students from Ljubljana university. More than 50 guests divided into 8 groups researched different segments of flora and fauna. Several HabiProt members helped guests to find the most attractive terain and exchanged experiences with them. Accommodation was well organized by Bela Palanka scouts, weather was nice, so guests returned with interesting findings and a lot of nice impressions.
