Across Europe, large carnivores are making a comeback. These top predators are often at the forefront of rewilding because they play an important role in the ecosystem as a keystone species. But, there are smaller, less well known carnivores in Europe that are equally deserving of our attention. The Scottish wildcat (Felis sylvestris) is the UK's only wild cat species and roams the glens and hillsides of the Scottish Highlands. Sadly, it is on the brink of extinction.
The Scottish Wildcat
The Scottish wildcat is a subpopulation of the European wildcat. It may look similar to a large tabby cat, but it has some key differences, most notably its distinctive thick tail with black stripes and a black blunt tip. Scottish wildcats rely on habitat complexity and are often found in woodland edges, where they can take shelter in the woodland but maintain access to open hunting grounds, perfect for hunting rabbits, voles and mice.
A History of Persecution
Once upon a time, wildcats were widespread across the British mainland. However, the wildcat has suffered centuries of persecution. Since medieval times, the wildcat was been hunted for sport and persecuted as “vermin”. From the mid-19th century, when many sport hunting estates were established, the wildcat was persecuted as part of a management strategy to increase numbers of trophy species, such as grouse and pheasant. The latest research suggests that, today, there are only 100-300 Scottish wildcats left, existing in small, isolated populations in northern Scotland.
Today, the Scottish wildcat is at risk of extinction. It faces a myriad of threats, from hybridisation with domestic and feral cats, to habitat fragmentation and disturbance. Wildcats and domestic cats can produce viable offspring and this threatens Scottish wildcats with a process known as genetic introgression, whereby the gene pool of the wildcat is gradually replaced by that of the domestic cat. It also faces the threat of disease from and competition with the domestic cat, accidental killing through predator control intended for other species and from dogs, fluctuations in prey densities and road accidents.
Scottish Wildcat Conservation
Though the future of the Scottish wildcat looks bleak, there are many scientists and conservationists working hard to protect the species. Extensive camera trapping surveys, control of feral cats and education and community outreach are underway to safeguard the future of the wildcat in Scotland. Though genetic rescue using wildcats from continental Europe is likely necessary, extensive captive breeding programmes are underway to save the gene pool of the Scottish wildcat. Our partner, Alladale Wilderness Reserve, is one of the organisations breeding Scottish wildcats, and in the last three years (2018 - 2020) they’ve welcomed eight new kittens. Though there is still much to be done, it’s not too late to save Scotland’s most threatened mammal.
