''This Project was supported by the Rufford Small Grant''
Summary Karst Viper is endemic and highly endangered snake species that inhabits high mountain areas in Balkans. This Viper is the smallest poisonous snake in Europe and is considered the most threatened one due to very fragmented distribution.teams of scientists from Serbia, Macedonia and Croatia have been working together on Karst Viper (Vipera ursinii macrops), for almost a whole decade but in Bosnia and Herzegovina there are no scientific research and conservation efforts in the field. Species is not protected by law, and habitats are being under anthropogenic pressure in enormous rate. In Bosnia and Herzegovina is 60 % of the range of V. ursinii macropsand our recent molecular and taxonomic research (FERCHAUD ET AL. in press) led us to amazing discovery that former V. ursinii macrops from Balkan Peninsula is actually divided in two separate phylogenetic lineages which meet in Bosnia and Herzegovina. With this project we wanted to precisely determine the distribution of Karst Viper (V.ursinii macrops) in Bosnia and Herzegovina, give description of high mountain habitats and their possible threats.through exchange of scientists, organizing workshops, lectures and publishing educational brochures we hoped to strengthen regional cooperation and after this short-term project to start research and monitoring in Bosnia and Herzegovina. Global endangerment: EN A1c+2c International protection: Habitats directive: Anex II and IV - proposed by Croatia to be added as priority species, Bern convention: Appendix II, CITES: Appendix I
Project in 2011/2012 This project is being organized by Croatian Herpetological Society Hyla in cooperation with Department of Zoology - University of Sarajevo and Banja Luka. The goal was to precisely determine the distribution of this species and develop an effective protection/monitoring program. Project is being organized in cooperation with scientists from Hungary, Serbia, Montenegro and Former Yugoslavian Republic of Macedonia so we could make a foundation for future regional protection of this species. Aims of the project I. Distribution research 1) determine the distribution of Karst Viper (Vipera ursinii macrops) in Bosnia and Hezegovina 2) investigate and analyze 16 mountains that have favourable habitats for Karst Viper II. Establishing monitoring of Karst Viper 1) find suitable localities to establish longterm monitoring in Bosnia and Herzegovina III. Education and awareness 1) exchange of scientists, strengthening of regional cooperation and local education through organization of workshops, lectures and publishing educational leaflets Project staff Project implementation unit: Dušan Jelić, project menager, Herpetological department of Croatian Biological Research Society and Croatian Herpetological Society HYLA Ivona Burić, project assistant, Croatian Herpetological Society HYLA Suvad Lelo, Ph.D., professor at Departement of Zoology, University of Sarajevo, Bosnia and Herzegovina

Distribution research During the project we tried to cover as much new localities as it was possible in order to inspect the habitat quality and to try to confirm the existence of Vipera ursinii macrops. During this field trips we collected data on the habitat and climatic characteristics, but also searched for all three Viper species present in Bosnia and Herzegovina. All other species of reptiles and amphibians were also documented. Figure 1. Distribution of Karst Viper in Balkan Peninsula (from JELIĆ ET AL. 2009)

Figure 3. V. ursinii abundance of records for localities Ecological niche suitability model Species distribution modelling provides new opportunities to reduce the costs of field research in a way of providing data on habitat suitability for the aimed taxa. Analysis of many aspects of ecology may be helped by the use of predictive models of species distribution (GRAHAM et al., 2004), including for instance modelling studies of invasive species spread, impacts of climate change, and spatial patterns of species diversity. Identifying species potential distribution is particularly advantageous / important from the perspective of conservation and management planning of endangered and poorly known species. Among many recently developed presence-only modelling approaches, Maxent machine learning method (PHILLIPS et al. 2006) has become widely used in conservation studies because of its excellent performance compared to other modelling techniques, especially when the presence data are limited (ELITH et al. 2006; HERNANDEZ et al. 2006) which is often the case with endangered and rare species, as well as with poorly-studied areas (Hernandez et al., 2008). Modelling potential distribution of a given species based on presence-only data is for example a useful tool for predicting new localities of presence for rare and threatened species that are hardly found in the wild, or for species that are simply very elusive and whose distribution is therefore little known. Karst Viper is one of the least known snake species in Europe and this is the reason we made and ecological niche model to indicate areas where Vipers could be found. Based on these results we can see that mountains Velež, Maglić, Prenj, Ujilica, Čabulja, Bjelašnica (near Trebinje), Sitnica, Golija and Njegoš are also all highly likely to have populations of Karst Viper and should be further researched in 2012./2013.

Only areas from 35-90% (orange and red) are considered as possible habitats and should be checked. II. Establishing monitoring of Karst Viper Figure 5. Location at mountain Zelengora selected for population monitoring due to the large population of Vipers, road access and lack of mine infested areas During the project we investigated several localities that were suggested to be selected for long term monitoring: Velež, Korita, Cincar and Zelengora. After considering all of the possibilities we decided to start the monitoring on mountain Zelengora (Fig. 5.) and taking mountain Velež as possible beckup. Monitoring will be done in two occasions (May and July) for 10 days and will serve as a gathering place for whole regional and Bosnia and Herzegovina team.
III. Education and awareness Through the project we planned promotional lectures at the University of Sarajevo, Banja Luka and Mostar to get students involved and invite them to a 3 day training on Zelengora Prenj mountain. All three lectures were held and for all three centres we have appointed a project focal point: Banja Luka mr.sc. Goran Šukalo (Biology department, University od Banja Luka); Sarajevo prof. Dr.sc. Suvad Lelo (Departement for agriculture, University of Sarajevo); Mostar Benjamin Jusić (University of Mostar), who all of the interested parties can address about the project activities and materials. Altogether around 200 students participated on the lectures in all three cities (four Universities) and 17 students were selected for the training in the Zelengora Prenj mountain (list of presons, their contacts and impressum are noted in the Guest book.xslx ). Some of them will be doing their Br.sc thesis through the project. Leaflet was prepared and printed in 3000 copies. They have been distributed during the lectures, through partner institutions (Universities) and during our field trips. Figure 7. Produced leaflets
