The Iberian lynx ( Lynx pardinus) is one of the four species within Lynx, a genus of medium-sized wild Felidae. The Iberian lynx is endemic to the Iberian Peninsula in southwestern Europe. It is listed as vulnerable on the IUCN Red List. In the 20th century, the Iberian lynx population had declined because of overhunting, poaching, fragmentation of suitable habitats, and the population decline of its main prey species, the European rabbit ( Oryctolagus cuniculus), caused by myxomatosis and rabbit haemorrhagic disease.
By the turn of the 21st century, the Iberian lynx was on the verge of extinction, as only 94 individuals survived in two isolated subpopulations in Andalusia in 2002. Conservation measures have been implemented since then, which included improving habitat, restocking of rabbits, translocating, reintroducing and monitoring Iberian lynxes. Between 2012 and 2024, the population had increased from a low of 326 individuals to some 2,021, leading to its reclassification as vulnerable. It is a monotypic species, and is thought to have evolved from Lynx issiodorensis.
The Iberian lynx genetically diverged as a unique species 1.98 to 0.7 million years ago. Its closest living relative is the Eurasian lynx ( Lynx lynx) with which it coexisted to a certain degree until the 20th century.
Fossil remains indicate that the Iberian lynx had a wider range during the Late Pleistocene and early Holocene. Five lynx remains found in Arene Candide in Northern Italy date to about 24,820–18,620 years before present. One specimen found in Cabias cave in southern France was to 3780±90 years before present. In 2021, a large concentration of Iberian lynxes dating to 40,000 years ago were identified for the first time in Southern Italy, at the fossil site of Ingarano in Apulia.Mecozzi, B., Sardella, R., Boscaini, A., Cherin, M., Costeur, L., Madurell-Malapeira, J., ... & Iurino, D. A. (2021). The tale of a short-tailed cat: New outstanding Late Pleistocene fossils of Lynx pardinus from southern Italy . Quaternary Science Reviews, 262, 106840.
The Iberian lynx prefers heterogeneous environments of open grassland mixed with dense shrubs such as Arbutus unedo, mastic, and juniper, and trees such as holm oak and cork oak. It is now largely restricted to mountainous areas.
The Iberian lynx has low adaptability and continued to rely heavily on rabbits, which account for 75% of its food intake, despite the latter's repeated population crashes due to myxomatosis and rabbit haemorrhagic disease. Fecal samples of Iberian lynx contained anaerobic bacteria of the genus Anaeroplasma that suggest gut microbiome helps it digest its rabbit prey and may also aid in the degradation of plant material from the rabbits' guts. Antibiotic resistant bacteria were also found within the digestive tract of wild Iberian lynx.
The Iberian lynx competes for prey with the Iberian wolf ( Canis lupus signatus), red fox ( Vulpes vulpes), the Egyptian mongoose ( Herpestes ichneumon), and the European wildcat ( Felis silvestris). Also, it often kills other smaller carnivores such as the aforementioned red fox, Egyptian mongoose and common genet ( Genetta genetta). Fossil leporid accumulations from the Late Pleistocene show that Iberian lynxes in Spain retreated to caves to rest and consume their meals.
Difficulty in finding mates has led to more inbreeding, which results in fewer kittens and a greater rate of non-traumatic death. Inbreeding leads to lower semen quality and greater rates of infertility in males, hindering efforts to increase the species' fitness.
In 2007, several individuals died of feline leukemia.
Increasing interactions with humans and spread of antibiotic resistant genes between lynx populations could pose a significant threat not only to lynx but also to humans.
Conservation measures include restoring its native habitat, maintaining the wild rabbit population, reducing unnatural causes of death, and releasing captive bred individuals.
The Spanish National Commission for the Protection of Nature endorsed the Iberian Lynx Ex Situ Conservation Breeding Program to serve as a "safety net" by managing the captive population and also to "help establish new Iberian lynx free-ranging populations through reintroduction programmes." Before release of captive-bred cats, their natural habit may be simulated to prepare them for life in the wild. A 2006 study used a non-intrusive monitoring system involving cameras to monitor the demographics of both lynxes and rabbits residing in Sierra Morena. Supplemental food sources could be provided if wild rabbits suffered a decline.
Management efforts have been developed to conserve and restore the animal's native range. Officials intending to release captive-bred lynx look for areas of appropriate habitat, rabbit abundance, and acceptance by the local human population. About 90 million euros was spent on various conservation measures between 1994 and 2013. The European Union contributes up to 61% of funding.
In November 2014, three Iberian lynxes were released in the Montes de Toledo; one of them later traveled near Aranjuez, in the Madrid region, the first time in 40 years.
The presence of Iberian lynxes in Portugal, particularly in the south, has been verified. In 2014, the Institute for Nature Conservation and Forests signed contracts securing 2,000 hectares of land for Portugal's reintroduction project.
In 2015, 10 captive-bred Iberian lynxes were released into Guadiana Valley Natural Park and surrounding areas in southeastern Portugal's Guadiana Valley. By the end of 2015, there were 400 lynx on the Iberian peninsula, the vast majority in Andalusia, in southern Spain, but with smaller new populations in the hills near Toledo, in Extremadura (south-western Spain) and in southern Portugal.
The reintroduction of Iberian lynx in Portugal has been a success; from 17 animals that were reintroduced, 12 have already established territories.
Since a 2007 outbreak of feline leukemia virus (FeLV), wild lynxes are tested periodically for possible disease. September–December 2013 samples were negative for FeLV but one male became the first of his species to test positive for feline immunodeficiency virus and was placed into quarantine.
In Portugal, the Centro Nacional de Reprodução do Lince-Ibérico established a breeding center near Silves, Portugal, and has since nurtured 122 individuals all born in the breeding center, of which 89 survived. 73 of them were reintroduced in the wild. Reintroduction takes place in Mértola and Serpa in the Guadiana Valley. As of 2020, there are around 140 individuals in the wild in Portugal spread through an area of approximately 50,000 hectares, 50 of them are cubs.
There were 14 surviving kittens in 2008 and 15 in 2009. In 2010, intense rain and health issues resulted in lower reproductive success, i.e. 14 born, eight surviving. But the next year, breeding centers recorded 45 births with 26 surviving kittens. In 2012, breeding centers in Portugal and Spain reported a total of 44 survivors from 59 births, while 2013 saw a total of 44 survivors out of 53 born. In 2017, the total population of Iberian lynx reached 475 specimens. In February 2019, the total population was estimated to grow to around 650 individuals.
In March 2013, it was reported that Iberian lynx and had been collected and preserved for the first time. They were collected from Saliega and another female—both sterilized and retired from the breeding program—by Berlin's Leibniz Institute for Zoo and Wildlife Research and stored in liquid nitrogen at the Museo Nacional de Ciencias Naturales in Madrid for possible future breeding. In July 2014, the MNCN-CSIC announced they had produced sperm cells from the testicular tissue of sexually immature lynx.
Iberian lynxes are kept at Jerez Zoo, at Lisbon Zoo since December 2014, and since July 2016 at the Madrid Zoo.
