Natrix natrix (Linnaeus, 1758)

Number of records.

39 (4.2% of the data).

Number of grid cells.

24 (8.1% of the entire grid; Table 1 ; Figs 5 , 9A ).

Comments.

This species is fairly frequently observed and distributed in different parts of the oblast ( Dotsenko and Radchenko 2005; Nekrasova 2013; Sillero et al. 2014). We found most individuals in the Oleksandrivske Reservoir and in the floodplains near Mykolaiv. Its range is similar to that of N. tessellata and these species can occur sympatrically. The records of N. natrix were fewer than those of N. tessellata presumably because there are not a lot of suitable habitats for this species in this oblast.
