Lynx

Eurasian lynx

Of the four lynx species, the Eurasian lynx (Lynx lynx) is the largest in size. It is native to European, Central Asian, and Siberian forests. While its conservation status has been classified as "least concern", populations of Eurasian lynx have been reduced or extirpated from much of Europe, where it is now being reintroduced. During the summer, the Eurasian lynx has a relatively short, reddish or brown coat which is replaced by a much thicker silver-grey to greyish-brown coat during winter. The lynx hunts by stalking and jumping on its prey, helped by the rugged, forested country in which it resides. A favorite prey for the lynx in its woodland habitat is roe deer. It will feed however on whatever animal appears easiest, as it is an opportunistic predator much like its cousins.[11]

Canada lynx

The Canada lynx (Lynx canadensis), or Canadian lynx, is a North American felid that ranges in forest and tundra regions[13] across Canada and into Alaska, as well as some parts of the northern United States. Historically, the Canadian lynx ranged from Alaska across Canada and into many of the northern U.S. states. In the eastern states, it resided in the transition zone in which boreal coniferous forests yielded to deciduous forests.[14] By 2010, after an 11-year effort, it had been successfully reintroduced into Colorado, where it had become extirpated in the 1970s.[15][16][17] In 2000, the U.S. Fish and Wildlife Service designated the Canada lynx a threatened species in the lower 48 states.[18]

The Canada lynx is a good climber and swimmer; it constructs rough shelters under fallen trees or rock ledges. It has a thick coat and broad paws, and is twice as effective as the bobcat at supporting its weight on the snow. The Canada lynx feeds almost exclusively on snowshoe hares; its population is highly dependent on the population of this prey animal. It will also hunt medium-sized mammals and birds if hare numbers fall.[13]

Iberian lynx

The Iberian lynx (Lynx pardinus) is an endangered species native to the Iberian Peninsula in Southern Europe. It was the most endangered cat species in the world,[19] but conservation efforts have changed its status from critical to endangered. According to the Portuguese conservation group SOS Lynx, if this species dies out, it will be the first feline extinction since the Smilodon 10,000 years ago.[20] The species used to be classified as a subspecies of the Eurasian lynx, but is now considered a separate species. Both species occurred together in central Europe in the Pleistocene epoch, being separated by habitat choice.[21] The Iberian lynx is believed to have evolved from Lynx issiodorensis.[22]

In 2004, a Spanish government survey showed just two isolated breeding populations of Iberian lynx in southern Spain, totaling about 100 lynx (including only 25 breeding females).[23] An agreement signed in 2003 by the Spanish Environment Ministry and the Andalusian Environment Council seeks to breed the Iberian lynx in captivity.[23] Three Iberian lynx cubs were born as part of the Spanish program in 2005, at the Centro El Acebuche facility in Doñana National Park.[23]

As a result of the Spanish government program and efforts by others (such as the WWF and the EU's Life projects), the Iberian lynx "has recovered from the brink of extinction";[24] from 2000 to 2015, the population of Iberian lynx more than tripled.[25] The IUCN reassessed the species from "critically endangered" to "endangered" in 2015.[24] A 2014 census of the species showed 327 animals in Andalucia in the "reintroduction areas" of Sierra Morena and Montes de Toledo (Castilla-La Mancha, Spain), the Matachel Valley (Extremadura, Spain), and the Guadiana Valley (Portugal).[24]

Bobcat

The bobcat (Lynx rufus) is a North American wild cat. With 13 recognized subspecies, the bobcat is common throughout southern Canada, the continental United States, and northern Mexico.[26] Like the Eurasian lynx, its conservation status is "least concern."[27] The bobcat is an adaptable predator that inhabits deciduous, coniferous, or mixed woodlands, but unlike other Lynx, does not depend exclusively on the deep forest, and ranges from swamps and desert lands to mountainous and agricultural areas, its spotted coat serving as camouflage.[28] The population of the bobcat depends primarily on the population of its prey.[29] Nonetheless, the bobcat is often killed by larger predators such as coyotes.[30]

The bobcat resembles other species of the genus Lynx, but is on average the smallest of the four. Its coat is variable, though generally tan to grayish brown, with black streaks on the body and dark bars on the forelegs and tail. The ears are black-tipped and pointed, with short, black tufts. There is generally an off-white color on the lips, chin, and underparts. Bobcats in the desert regions of the southwest have the lightest-colored coats, while those in the northern, forested regions have the darkest.[10]

The Eurasian lynx ranges from central and northern Europe across Asia up to Northern Pakistan and India. In Iran, they live in Mount Damavand area.[31] Since the beginning of the 20th century, the Eurasian lynx was considered extinct in the wild in Slovenia and Croatia. A resettlement project, begun in 1973, has successfully reintroduced lynx to the Slovenian Alps and the Croatian regions of Gorski Kotar and Velebit, including Croatia's Plitvice Lakes National Park and Risnjak National Park. In both countries, the lynx is listed as an endangered species and protected by law. The lynx was distributed throughout Japan during Jōmon period; with no paleontological evidence thereafter suggesting extinction at that time.[32]

Several lynx resettlement projects begun in the 1970s have been successful in various regions of Switzerland. Since the 1990s, there have been numerous efforts to resettle the Eurasian lynx in Germany, and since 2000, a small population can now be found in the Harz mountains near Bad Lauterberg.

The lynx is found in the Białowieża Forest in northeastern Poland, in Estonia and in the northern and western parts of China, particularly the Tibetan Plateau. In Romania, the numbers exceed 2,000, the largest population in Europe outside of Russia, although most experts consider the official population numbers to be overestimated.[33]

The lynx is more common in northern Europe, especially in Norway, Sweden, Estonia, Finland, and the northern parts of Russia. The Swedish population is estimated to be 1200–1500 individuals, spread all over the country, but more common in middle Sweden and in the mountain range. The lynx population in Finland was 1900–2100 individuals in 2008, and the numbers have been increasing every year since 1992. The lynx population in Finland is estimated currently to be larger than ever before.[34] Lynx in Britain were wiped out in the 17th century, but there have been calls to reintroduce them to curb the numbers of deer.[35]

The endangered Iberian lynx lives in southern Spain and formerly in eastern Portugal. There is an Iberian lynx reproduction center outside Silves in the Algarve in southern Portugal.

The two Lynx species in North America, Canada lynx and bobcats, are both found in the temperate zone. While the bobcat is common throughout southern Canada, the continental United States and northern Mexico, the Canada lynx is present mainly in boreal forests of Canada and Alaska.[26]
