Abstract: Data were obtained during traditional autumn trapping of the Edible dormouse Glis glis in the mixed montane forests of central Slovenia, between 1968 and 2000. Altogether 2235 dormice were trapped in 4335 trap nights. Fifteen years were of low population density, three years were of medium density and fifteen years were of high density. The mean duration of a low density phase was 1.50±0.707 years (range 1–3; N = 10) and of a high density was 1.25±0.452 years (range 1–2; N = 12). The mean interval between low densities was 1.56±1.014 years (range 1–4; N = 9) and between high densities was 1.55±0.820 years (range 1–3; N = 11). Thus, on average, approximately 1.5 years of high density were followed by a similar period of low density, a pattern roughly suggesting three years cyclicity. Juveniles strongly predominated in high density years, but not in low density ones. Autoregressive moving average model (ARIMA) time series analysis of population densities did not uncover any pattern, consequently the resulting model had no predictive power.
