In this report of substantial syntopic populations, southern bog lemmings (Synaptomys cooperi) and woodland voles [Microtus (Pitymys) pinetorum] were the co-dominant rodents in a grassy oldfield in the absence of the large-bodied species of rodents common to the region. Southern bog lemmings achieved densities of 14 ha−1 on one grid and woodland voles had a peak density of 32 ha−1 on the other. Both species bred at high levels during the 18-mo study, including during the winter months.
