Eurasian Lynx

Eurasian Lynx: Species Facts

Range & Habitat

The Eurasian lynx is the largest European cat and lives in extensive forests. According to the IUCN Large Carnivore Initiative for Europe (LCIE), it is solitary and territorial, with little overlap between animals of the same sex, and its home ranges vary from 120 to 1,800 km² for males and from 80 to 500 km² for females. Males weigh 18–25 kg and females 12–16 kg; lynx mate in March and the young are born in May–June, in litters of one to four, normally two or three.^[2][4]

It is strictly carnivorous. In the mixed and deciduous forests of the Palaearctic its main prey are wild ungulates, primarily roe deer, but also red deer and chamois, according to a 2025 review of large carnivores in Poland, which adds that in Poland red deer is the most commonly killed of the three. LCIE also lists hares, forest birds, domestic sheep and semi-domestic reindeer. A 2025 study of 107 GPS-collared lynx from nine European populations found that the interval between kills of adult ungulates ranged from about 3 to 9 days depending on the population, while lynx spent about 2 to 3 days feeding on each kill.^[2][4][6]

A 2024 study that GPS-tracked 35 lynx in the Western Carpathians (Slovakia, Czechia and Poland) between 2011 and 2022 found average annual home ranges of about 283–360 km² for males and 148–190 km² for females, depending on the method used. The availability of roe deer explained home-range size, except in summer, and higher road density made home ranges larger. For the Polish Carpathians, the 2025 review gives an average range of 171 km².^[4][5]

In the Bieszczady National Park, in the south-east of Poland, the vegetation is arranged in belts, with the subalpine meadows known as połoniny above the montane beech forests. According to the park, six adult lynx range into it, with territories of up to 150 km². Lynx are more secretive than the park's wolves and bears, cross human trails far less often, spend their time among the mountain ridges and travel on average 7 km a day. There are far fewer of them because roe deer are scarce: very few live at higher elevations (about 80 in the park on average), and winter tracking shows lynx appearing more often where roe deer gather, the most important part of their diet.^[8][9]

Red deer are the most numerous ungulates in and around the park, with seasonal numbers of 140–600 inside it (370 on average). In autumn they hold their rut among the połoniny, where, according to the park, mating takes place undisturbed, away from the hunting grounds organised around the park.^[8]

Statistics Poland (GUS), using data from the General Directorate for Environmental Protection (GDOŚ), recorded 636 lynx in Poland in 2024, 334 of them in the Podkarpackie province, the province of the Bieszczady. GUS describes these figures as estimates, gathered once a year from the same sources (State Forests units, national parks, earlier surveys and the literature) rather than from fieldwork using a single method. A 2024 study states that lynx numbers in the Polish part of the Carpathians do not exceed 100, so the figures should be read with that caution. Earlier figures, for the record (GUS/GDOŚ estimates for Poland): 192 lynx in 2003, 285 in 2010, 390 in 2015, 580 in 2020 and 630 in 2023; in Podkarpackie, 342 in 2019 and 304 in 2023.^[1][5][8]

Across the Carpathians, from Romania to the Czech Republic, LCIE's status assessment for 2017–2022/23 puts the population at 2,687 lynx and increasing, the largest of the European lynx populations it lists (Karelian 2,483; Scandinavian 1,820). The European Commission, presenting the same LCIE work, estimates about 9,400 lynx in Europe in 2023, 12 % more than in 2016, and describes the Carpathian population as increasing only slowly.^[2][3]

Threats

Illegal killing. A 2025 study of 681 radio-tracked lynx across Europe found that illegal killing was the main cause of death (33.8 %), and that mortality rates were similar in protected and hunted populations. Lower survival went with more human-modified landscapes, and the authors conclude that keeping refuge habitat with little human disturbance is critical to lynx conservation. LCIE names poaching as one of the major threats to lynx survival throughout Europe, and the 2025 review notes that in Poland lynx are still killed illegally and can be caught in poachers' traps set for deer, which are illegal.^[2][4][7]

Loss and fragmentation of forest. The 2025 review says the lynx declined markedly in Europe over the past five centuries, probably because of deforestation, hunting pressure on lynx and their prey and infrastructure that fragmented its habitat. In Poland, the lack of connectivity between the forests of the west and north-west and those of the north-east and east remains a major problem, and forests stripped of old and fallen trees and undergrowth leave fewer places to rest and raise young and reduce hunting success. In the Western Carpathians, higher road density made lynx home ranges larger.^[4][5]

Pressure around the Bieszczady National Park. The park calls the lynx the most vulnerable species within its borders, because of its low numbers and reproduction combined with growing human pressure. It reports increasing clear-cutting right around the park, a shift to fast, car-based tourism that creates barrier effects along roads and at car parks, and uncontrolled building, which it calls the main cause of broken ecological corridors in the Carpathians.^[8]

Losing kills to scavengers. The 2025 continental study found that the presence of dominant scavengers (wild boar and brown bears) and greater human impact shortened the time lynx spent feeding on their kills, which suggests these may limit the energy lynx obtain from their prey. In the Bieszczady National Park, a tracked male bear was recorded taking a roe deer killed by a female lynx with her previous year's young.^[6][8]

Conservation Status & Work

Lynx lynx: Least Concern on the IUCN Red List (global assessment of the species, published in 2025). That category describes the Eurasian lynx as a species across its whole range; it is not the status of the Carpathian population or of lynx in Poland.^[10]

In Poland the Eurasian lynx has been under strict legal protection since 1995, under the Act on Nature Conservation and the ministerial regulation on the protection of animal species. In the EU it is listed in Annexes II and IV of the Habitats Directive 92/43/EEC.^[4][5]

Bieszczady National Park was created on 4 August 1973 and later enlarged, and nearly 70 % of its area is under strict protection. It became part of the East Carpathians International Biosphere Reserve in 1992 and of the Natura 2000 site «PLC 180001 Bieszczady» in 2004, and in July 2021 four areas of its beech forests were inscribed on the UNESCO World Heritage List as part of the «Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe».^[8][9]

The park describes the Bieszczady as Poland's most important breeding ground for large carnivores and a source of animals that settle elsewhere in the country, and says protecting carnivores and their habitats is a duty of the state under Article 12 of the Habitats Directive.^[8]

Carpathian lynx matter beyond the Carpathians. LCIE says many reintroduced populations in central Europe are very small and potentially inbred, and need more animals from the Carpathians and greater connectivity. In western Poland, according to the 2025 review, lynx have returned through reintroductions supervised by a programme of the West Pomeranian Nature Society with the Mammal Research Institute of the Polish Academy of Sciences, and WWF Poland has taken part in reintroductions in the north since 2018; GUS figures for the Zachodniopomorskie province rose from 34 lynx in 2019 to 106 in 2024.^[1][2][4]

The 2025 review calls for networks of corridors so that lynx can move safely, continued monitoring of the population and wider knowledge about the species. The authors of the 2024 Western Carpathian study say their results will improve the accuracy of population estimates and of mitigation measures in the region.^[4][5]
