| Summary: | In this paper, we present our dataset containing up-to-date information about occurrences of small mammals (Erinaceomorpha, Soricomorpha and Rodentia) on the territory of the Samarskaya Luka. It is a bend of the Volga River in the southern part of the forest-steppe zone of the Russian Plain (European Russia). This unique territory is surrounded on almost all sides by water. The dataset summarizes small mammal occurrences noted in long-term studies in the Samarskaya Luka from 2000 to 2020. A major part of the dataset was obtained during our helminthological study of micromammals. Besides, some data were attained when studying the ecology of tree-dwelling rodents. Our studies of small mammals were conducted by trap lines and direct observations in the wild. The dataset includes 8147 records of erinaceomorphs, soricomorphs and rodents of 26 species (of total 28) belonging to 3 orders, 9 families and 21 genera. It is based on the research of the staff of the Institute of Ecology of the Volga River basin of the Russian Academy of Sciences and the Zhiguli State Nature Reserve. The distribution of erinaceomorphs, soricomorphs and rodents in the Samarskaya Luka has not been fully studied and further investigation will note new small mammal habitats.Our dataset contains new information on occurrences of erinaceomorphs, soricomorphs and rodents in the Samarskaya Luka (European Russia). All occurrence records of 26 mammal species with georeferencing are published in GBIF for the first time. The occurrence data are stored in our field journals and we would like to make them available to all researchers.
