Abstract

There are 59 species of amphibians and reptiles in Croatia and Bosnia and Herzegovina, so there is a need to assess their sensitivity, since the endangerment assessments in the Red List take into account only the geographical distribution, and not the ecological parameteres. In this paper a number of variables is singled out, which include ecological, biological, geographical, and anthropological factors. For each species and variable one of four categories was asigned: from 0 - the lowest, to 3 - the highest sensitivity. Data for each type is obtained from examining the literature, and also from experts' personal experiences. The sensitivity index of each species was calculated as the sum of values of all variables and divided by the number of variables. A correlation of the sensitivity index and the national status of endargement in the Red List was made, and important herpetological areas were defined using three maps. The results show that reptiles are more sensitive than amphibians. Also, the resulting sensitivity indices correlate well with the assessments in the Red List, with few exceptions. Species Testudo hermanni, Zamenis situla and Iberolacerta horvathi are highly sensitive, so their low endangerment status should be reviewed. Important herpetological areas spread across most of the Croatian coast, and a large part of the Dinarides. In conlusion, the assessment of sensitivity of the herpetofauna gives a better endangerment assessment than those that can be found in the Red List.
