Populations of Coronella a. austriaca, a species which is a rapidly disappearing species in mid-western Poland, have been examined for 16 years. In 13 out of 16 recorded sites 1-2 live or dead individuals were observed. Populations consisting of up to several dozen individuals were observed in the valleys of the Bobr, Odra, Ilanka and Pliszka rivers. 76% of the observations were conducted on anthropogenic and 24% on primary sites. In total 248 individuals were examined, including 38 (15.3%) males, 36 (14.5%) females, 8 (3.2%) young/subadult individuals and 166 (67%) neonates.
