The importance of Robinia pseudo-acacia stands as a food supply for four species of small mammals, Apodemus sylvaticus (Linnaeus, 1758), A. flavicollis (Melchior, 1834), Clethrionomys glareolus (Schreber, 1780), Microtus arvalis (Pallas, 1778) was studied. The trophic diversity and equitability in all rodent species suggested a rich food supply. Greater trophic overlap as well as greater qualitative and quantitative similarity of food was found in both species of Apodemus only. Robinia stands not only represented a refuge but also offered enough food for all four species of rodents.
