The European wildcat (Latin: Felis silvestris silvestris) is a subspecies of the wildcat that inhabits European forests, as well as forested areas in Turkey and the Caucasus Mountains. It is absent in Scandinavia, and has been extirpated in England and Wales. Numbers in Scotland are critically low.[2]

Predominantly nocturnal, the European wildcat is active in the daytime in the absence of human disturbance.[3][4]

Populations in Scotland, the Mediterranean islands, Turkey, and Caucasus used to be considered separate wildcat subspecies and distinct from wildcats occurring on the European mainland.[1]

Characteristics[edit]

The European wildcat is much bigger and stouter than the domestic cat, has longer pelage and a shorter non-tapering bushy tail. It has a striped fur and a dark dorsal band.[5] Males average a weight of 5 kg (11 lb) up to 8 kg (18 lb), and females 3.5 kg (7.7 lb). Their weight fluctuates seasonally up to 2.5 kg (5.5 lb).[6]

Since European wildcats and domestic cats interbreed, it is difficult to distinguish European wildcats and striped hybrids correctly on the basis of only morphological characters.[7]

Evolution[edit]

In European Pleistocene deposits, remains of small cats are not common, and indicate a close relationship to the European wildcat.[8]

Threats[edit]

In most European countries, European wildcats have become rare. Although legally protected, they are still shot by people mistaking them for feral cats. In the Scottish Highlands, where approximately 400 were thought to remain in the wild in 2004, interbreeding with feral cats is a significant threat to the wild population's distinctiveness.[9] The greatest population of wildcats lives in Spain and Portugal but is threatened by interbreeding with feral cats and loss of habitat.[10][11] In the 1990s, the easternmost population in Ukraine, Moldova, and the Caucasus was threatened by destruction of broad-leaved forests, entailing a reduction of their range. Only small numbers occur in protected areas.[12]

Conservation efforts[edit]

In Scotland[edit]

In 2012, conservationists reported to have discovered a previously unknown population of Scottish wildcats in the Cairngorms National Park. They are still threatened because of crossbreeding with domestic and feral cats. The scientists reported 465 potential sightings.[13][14][15] In response, the Scottish Wildcat Association disputed the claims stating in their website, social networks, and press interviews that the sightings were defined as hybrid crossbreeds by leading experts, and that the wildcat population was likely well below 100 individuals.[16]

In September 2012, following a review of 2,000 records including camera trapping photographs, sighting reports, and road kills, the Scottish Wildcat Association (SWA) warned that Scottish wildcats could be extinct within a short time, because only 35 pure wildcats survive in the wild.[17] A severe reduction of rabbit populations due to myxomatosis has hastened the wildcat's decline.[18] In 2013, the Royal Zoological Society of Scotland encouraged collection of biological material, but considered cloning as an option only after "all other avenues have been exhausted."[19]

In September 2013, the Aspinall Foundation announced plans to develop an in-situ captive breeding centre on the island of Càrna, off the West coast of Scotland at Ardnamurchan.[20] The Scottish Wildcat Association had developed the Wildcat Haven project on this peninsula to identify pure Scottish wildcats and neuter feral cats, using a genetic test to identify hybridisation in Scottish wildcats.[21][22][23]

The news was followed by an SNH announcement to launch a new wildcat Action Plan taking a more "pragmatic" approach to conserve wildcats and hybrids exhibiting wildcat features using a relaxed definition of the wildcat.[24][25] The founder and former chairman of the Scottish Wildcat Association however considered the approach a "shameful effort" that would force the Scottish wildcat into extinction.[24][26][27]

In July 2014, the Wildcat Haven project announced the successful neutering of feral and hybrid cats across 250 sq mi (650 km2) of the West Highlands, creating a protected zone for the Scottish wildcat.[28][29]

Taxonomy[edit]

Two different forms often are identified in the Iberian Peninsula: the common European form, north of the Douro and Ebro Rivers, and a "giant" Iberian form, sometimes considered a different subspecies F. s. tartessia, in the rest of the region.[30] The largest "Tartessian" males may reach 65 cm (26 in) in length, plus a 34.5 cm-long (13.6 in) tail, and weigh 7.5 kg (17 lb). They also have a less diffuse stripe pattern, proportionally larger teeth, and feed more often on rabbits than the wildcats north of the Douro-Ebro, which are more dependent on small rodents.[31] In his book Pleistocene Mammals of Europe (1963), palaeontologist Dr. Björn Kurtén noted that the disputed "Tartessian" subspecies has uniquely kept the same size and proportions as the form that was found throughout mainland Europe during the Ice Ages of the Pleistocene. The habitat of both forms also is different: the northern silvestris lives mainly in deciduous Quercus robur forests and the southern tartessia in Mediterranean evergreen Quercus ilex forests.[31]

Many authorities restrict the subspecies F. s. silvestris to the populations of the European mainland.[1] But in 2007, a genetic study suggested that the European populations, as well as populations in Sicily, Anatolia, and the Caucasus Mountains belong to this subspecies as well; on the other hand, populations in Corsica, Sardinia, Crete, and Cyprus turned out to be introduced African wildcats.[32] As per the old classification that considered several different subspecies, the small population of Scottish wildcats is F. s. grampia, the Caucasian wildcat (also including wildcats in Turkey) is F. s. caucasica, the possibly extinct Crete wildcat is F. s. cretensis, the Balearic wildcat is F. s. jordansi, and the possibly extinct Corsican wildcat is F. s. reyi.[1]
