Moreover, there is a need for basic information on the effectiveness of control methods and management strategies that can be used. In this note we report on a successful lowtecheradication campaign of a local population of Pallas’s squirrel Callosciuruserythraeus, a species of tree squirrel with documented ecological andsocioeconomic impacts in its invasive range. The population was eradicated from a suburban park of about 15 ha using baited mesh wire life traps, in five consecutive capture campaigns between October 2005 and January 2011. Using maximum likelihood estimation from catcheffort data we calculated initial densities in the park at 3 squirrels ha. Although control started quickly and the extent of the invasion was limited, the campaign took over 5 years and required an estimated investment of over €200,000 including 1.5 years of posteradication surveying. We provide basic data on the methods used to eradicate this invasive rodent. Critical success factors and possible improvements with respect to the specific context of this case are discussed. Adding this species to the list of species of EU concern currently under development could provide incentive to minimise impact of this tree squirrel at the continental scale.",
