Regulated invasive species of Union concern under the European Regulation on the prevention and management of the introduction and spread of invasive alien species [1147/2014].
Cat sized omnivorous mammal with distinctive black and white face, tail with black rings.
Raccoons are carriers or possible carries of a large number of disease such as West Nile virus, rabies, canine distemper, as well as carrying the zoonotic roundworm Baylisascaris procyonis (raccoon roundworm) (Beltrán-Beck, et al., 2013). Raccoons in Polish wetlands and forest were found to consume 44% mammals, 41% other vertebrates, 12% invertebrates and only 1% eggs and 16% birds (Bartoszewicz et al., 2008), though raccoons show high behavioural plasticity and effects in Ireland are unlikely to follow a similar pattern.
Woodland, forest and other wooded land; Constructed, industrial or other artificial habitats; Regularly or recently cultivated agricultural, horticultural or domestic habitat; Heath, scrubland & tundra
Generally 1 litter per year producing 2-4 young (Winter, 2009).
There is currently an EU wide ban on the sale of this species and personal and zoo ownership is being phased out (European Commission, 2017).
Control is possible in isolated areas with small numbers of raccoons. Once invasion is in full progress the risk of a compensatory response to culling (by an increase in the reproductive rate) increases (Kotani et al., 2009). Most effective control is achieved outside the breeding season when the animals spend more time outside in the open (Harfenist et al., 2000).
Commonly used methods in Europe are hunting (sometimes with dogs) and live-trapping. However, these efforts do nothing to reduce the expansion rate of this species (Bartoszewicz, 2011). Zalewski (personal observation in Zalewski, 2011) considers trapping to be more effective than hunting. However, on rocky Canadian islands in order to protect nesting seabird colonies, eradication has been achieved by shooting. This method was used over trapping or hunting with dogs due to the inability of man and dogs to cross the difficult terrain. Shooting was carried out from boats at night using a spotlight (Harfenist, et al., 2000)
Can occupy a range of habitats and though not an obligate commensal often found in association with humans and in urban areas in both its introduced and native range (Winter, 2009).
Distribution frequency in Ireland
Present in the Wild - Rare/Localised. Species can survive in the wild but unlikely to have established a breeding population due to scattered nature of records.
Native to North America from southern Canada to Panama, have been introduced to a large part of continental Europe, as well as Russia and Japan (Winter, 2009).
