The distribution, ecology and conservation status of the Syrian urodeles Salamandra infraimmaculata and Ommatotriton vittatus are poorly known. We present the results of a field study, conducted in February 2009. Salamandra infraimmaculata was found at six localities, ranging from 228 to 960 m a.s.l., and co-occurred with O. vittatus at three localities. All localities were near small, clear streams or springs. Temperatures ranged from 9.4 to 16.4°C, pH 7.5–8.5, GH 3–18 and KH 3–18. The distribution model of S. infraimmaculata reveals that the distribution of this species is nearly entirely shaped by precipitation in the coldest quarter “92.9% contribution to the model”. The rarity of suitable surface waters is probably the main reason for the supposed scarcity of this species in northwestern Syria. Tapping a water source for drinking water resulted in one case in extensive mortality of larvae. Ommatotriton vittatus was found at nine different localities, ranging from 172 to 960 m a.s.l. Habitat characteristics, water quality and morphological data were recorded. The average total length of adult O. vittatus was 116 mm (range 93–138 mm, n = 22) for males and 93 mm (range 86–108 mm, n = 34) for females. Mean weight was 6.7 g for males and 3.9 for females. The mean body condition index of females was comparable to that of males. Water temperatures ranged from 8.7 to 14.6°C, pH 7.5–8.5, GH 3–18 and KH 3–18. The distribution model of O. vittatus reveals that the distribution of this species is mainly shaped by precipitation, both during the winter and summer periods. The collection of large numbers of adult O. vittatus for fish bait was observed.
