We studied demography and spatial organization in a population of root voles Microtus oeconomus (Pallas, 1776) inhabiting a fenced, linear habitat (560 x 1.5 m) during the breeding season, using live trapping and radiotelemetry. There were no establishments of new reproductive individuals. Compared to root voles in non-linear habitats, home ranges were extremely small and no male home ranges overlapped. A short term removal and reintroduction experiment (2 days removal of every second individual on the study area) produced no changes in home range size, indicating that home range borders were not defended by daily contact between neighbours.
