Recent studies on the world reptiles' extinction risks pointed out that
about 20 \% of species are threatened, with another 20 \% are
data-deficient following IUCN criteria. IUCN set up criteria for
assessment of extinction risk at global and regional scales, relying on
distribution data, population parameters and quantitative analyses. Only
12 \% of reptilian species were listed as globally threatened upon
population data. Long-term population studies are time-consuming, thus
it would be practical to use some other parameters for estimations of
extinction risks. Threatening level (and extinction risks) of Serbian
reptiles have never been investigated. We aimed to scrutinize species
threatening level (thus set up conservation priorities) on the basis of
distributional, ecological and life-history datasets (DELH). We
estimated which traits are the most important for the conservation of
species. Separately, we used IUCN criteria for regional level to assess
extinction risk and compared them with the results obtained by analyses
of DELH datasets. The two types of criteria gave similar estimates for
the chelonian species. In snakes, two species exhibited higher
conservation scores by DELH than by IUCN criteria, the opposite being
true for two other species. In lizards, only two species had higher
extinction risks by IUCN whereas five lizards were more threatened
according to DELH. Our intention was not discredit the values of IUCN
criteria for setting regional (or national) extinction risks, but to
suggest that use of additional features other than IUCN could be
valuable for estimation of threatening level and setting conservation
priorities for cases where precise distribution and population data are
not available.
