Testing restocking methods for an endangered species: Effects of predator exclusion and vegetation cover on common hamster (Cricetus cricetus) survival and reproduction

► We released captive bred hamsters in various conditions to improve restocking success. ► Survival and reproduction were better inside electric fences than in control areas. ► Sudden lack of vegetative cover due to harvest strongly decreased hamsters' survival. ► Survival seemed better in females and decreased with frequency of burrow change. ► Fences with well-developed cover are more suitable for releasing than unfenced and harvested plots.
