Mammals of Israel

Israel's mammal diversity reflects its location at the junction of three continents and the meeting of several climatic and biogeographic regions.[1][3] Mediterranean conditions characterize much of the north, desert dominates the south, and central Israel forms a transition between them.[3] Many species consequently occur near the edges of their natural ranges.[6]

A 2011 academic article argues that Israel qualifies as a Palaearctic provincial biodiversity hotspot for mammals, birds, and reptiles. It attributes much of this diversity to turnover between geographic grid cells—beta diversity—rather than consistently high species richness within each cell.[5]

During the Pleistocene, animals associated with East African savannas, including hippopotamuses, rhinoceroses, warthogs, and several gazelles, entered the region; wild horses, wild asses, wolves, and badgers later arrived from western and central Asia.[1] Climate change, forest destruction, hunting, and the spread of firearms contributed to subsequent losses.[1] One overview estimates that at least 15 large mammal species disappeared compared with biblical-era fauna, while another source reports that nine of 133 terrestrial species present at the beginning of the twentieth century became locally extinct during its first half.[2][6]

Fossil and archaeological records document a mammal fauna broader than that found in Israel today. Sources identify remains of hippopotamuses, rhinoceroses, warthogs, elephants, and extinct gazelle taxa, although they do not provide a unified chronology for their disappearance.[1][8] A Mosaic editor's pick similarly notes that lions and bears no longer inhabit the Land of Israel and that elephants and baboons lived there further back in time.[9]

Excavations at Naḥal Rimmonim in the Jezreel Valley recovered 421 identifiable animal bones from five Intermediate and Middle Bronze Age strata. The assemblage indicates an economy combining animal husbandry with hunting, predominantly of gazelles, while pigs were the most common animals in domestic levels.[10]

The Asiatic lion probably disappeared from the region by the thirteenth century, while the Syrian bear survived until the nineteenth century.[11] More generally, available sources associate faunal losses with climatic change, forest destruction, hunting, and the increased effectiveness of firearms from the late nineteenth century.[1]

The Protection of Wild Animals Law defines a wild animal as a mammal or bird "which does not by its nature live in association with man." Hunting a protected wild animal requires a special license, generally issued for limited purposes such as research, breeding, ecological management, agricultural protection, public safety, or disease control.[7] Marine mammals in Israeli waters are also protected under Israeli law.[12]

The Nature Reserves Authority, established in 1964, was a predecessor of the Israel Nature and Parks Authority, formed through an institutional merger in 1998.[2][13] Wildlife management now includes long-term counts, camera-trap surveys, habitat protection, and monitoring of species such as gazelles, ibex, otters, carnivores, and bats.[14][13] Development, settlement expansion, population growth, and tourism continue to place pressure on previously undisturbed habitat.[2]

Israel has operated mammal restoration programs since the 1960s through the Hai-Bar reserve system. Hai-Bar Yotvata focuses on desert species, while Hai-Bar Carmel supports Mediterranean and forest species.[1][3] Sources date successful returns of Asiatic wild asses to 1982, Persian fallow deer to 1996, and white oryx to 1997.[1]

Accounts of the Persian fallow deer program give different details about its founding stock. An academic chronology says the permanent Hai-Bar Carmel breeding core was established in 1976 from two males and five females, while a later news account says the program began with three deer from Germany in 1976 and four from Iran in 1978.[15][16] By the mid-1990s, the breeding core included nearly 50 adult females.[15] After three release cycles, more than 40 deer lived in several wild subpopulations, and fawns were born during the first two fawning seasons.[17] A later report estimated about 300 deer in the Upper Galilee.[16] Expansion to a less favorable Judean Hills site in 2003 was complicated by poor habitat linkage and behavioral problems among zoo-origin animals.[15]

Six of ten assessed medium- and large-sized mammal species increased, including hares, porcupines, wolves, jackals, foxes, and gazelles, although road strikes and dependence on human food waste remain concerns.[4] The Indian palm squirrel and nutria are established invasive mammals.[4] Along the southern Israel–Jordan border, 40 camera traps recorded 4,181 mammal crossings during 44 nights, but larger animals such as Dorcas gazelles and striped hyenas could not use the existing passages.[18]

Israel's mammals are significant both as components of a biogeographically varied fauna and as indicators of ecosystem condition. Gazelle counts are used to evaluate changes in habitat quality, while long-term ibex and otter surveys reveal whether conservation measures are maintaining populations.[19][13]

Mammals also provide ecological and economic functions. DNA analysis confirmed that bats foraging in southern Arava date plantations consumed agricultural pests.[20] Reintroduced Persian fallow deer disperse seeds and alter forest structure, illustrating how restoration can reestablish ecological processes as well as individual species.[15]

Three gazelle taxa are described in Israeli sources. The Israeli gazelle (Gazella gazella gazella) is presented as a locally distinct form of Gazella gazella that formerly ranged more widely in neighboring countries.[11] Most of its surviving population is now in Israel, from northern and central areas to the western Negev and northern Judean Desert.[13] An earlier article estimated about 2,000 animals, while a 2020 monitoring report estimated about 5,500; the sources concern different dates and do not reconcile the totals.[11][13] Habitat loss, agriculture, predation, stray dogs, and hunting are among the reported threats.[11]

The Dorcas gazelle (Gazella dorcas) occupies the Negev and Arava, from the southern western Negev and Dead Sea coast to Eilat.[11][13] Surveys in five representative areas found an increase approaching a doubling, with 1,433 counted in 2018.[13] This desert-adapted species can obtain moisture from acacia leaves.[11]

Sources use differing terminology for the acacia gazelle. A Ynet article describes it as a gazelle form unique to Israel, while an academic study calls the population both the Acacia gazelle and a population of Arabian gazelle.[21][11] The study recorded 22 individuals in a 3.5-square-kilometer enclosure shared with more than 120 Dorcas gazelles and found a higher browsing line than in comparison habitats, suggesting consequential browsing pressure.[21]

Gazelles were nearly extinct locally in the early 1940s, but their numbers increased after hunting became an offense under wildlife-protection law.[22] The Nubian ibex (Capra nubiana) likewise became a flagship of Israeli conservation and has generally shown stable or modest population growth.[13] Twenty years of sighting records identified three principal Negev population cores and emphasized the importance of protecting steep core habitat and connecting corridors.[23]

Wild boar are frequently detected in Mediterranean woodland and planted forests and thrive in parts of the Golan where human activity provides accessible food and water.[14][24] The Persian fallow deer, once believed extinct, has been reintroduced to several Israeli regions, with an Upper Galilee population reported at around 300.[16]

Israel is described as a meeting point for Indian and Arabian wolf subspecies, which interbreed in the country.[24] Wolves occur most prominently in the Golan and Arava, with additional populations in the Negev, Judean Desert, Galilee, and Carmel. The national population is characterized as small but stable.[24] They prey on young wild boar and gazelles and also consume dates, melons, and cherries. In the Golan, researchers proposed that wolves may indirectly benefit gazelles by displacing jackals that threaten fawns, but presented this as an interpretation rather than demonstrated causation.[24]

A 1964 poison campaign intended to control rabies nearly exterminated golden jackals while only mildly affecting red foxes. Jackals later recovered and recolonized southern Israel.[25] Genetic analysis of 88 jackals and 89 foxes found high diversity, relative isolation of central populations, and evidence consistent with the Jordan Rift Valley serving as a migration corridor.[25]

A 47-year analysis reported a 68% increase in Israel's striped hyena population and an estimated density of 2.1 animals per 100 square kilometers.[26] Researchers proposed increased prey availability, predation on livestock, leopard extinction, and hunting of wild boar and other agricultural pests as contributing factors; improved monitoring also increased detection.[26] Camera traps recorded hyenas more often than expected for a species considered rare.[14]

Five radio-collared Arabian leopards were studied in the Judean Desert between 1986 and 1990. Wild mammals formed 75.8% of their diet, especially Nubian ibex, rock hyrax, and Indian porcupine, while domestic animals formed 24.2%.[27] Plastic, cloth, and aluminum in scats indicated human encroachment. The area was then one of the leopard's last regional strongholds, but later research refers to the leopard as extinct in Israel.[27][26]

The caracal occurs throughout Israel but is rarely seen and is threatened by habitat loss.[28] Smaller carnivores include mongooses and marbled polecats, nocturnal predators of rodents, small mammals, and birds.[29] The Eurasian otter is critically endangered in Israel, with fewer than 100 estimated individuals concentrated in the Upper Jordan basin, Hula Valley, Sea of Galilee region, and Jordan Valley.[19] Habitat degradation, pollution, infrastructure, and road mortality threaten the remaining population.[19]

Rodents are Israel's most species-rich mammal order, with about 32 species reported.[6] Research on six desert species found distinct associations with sandy and rocky habitats but cautioned that population density and spatial or temporal variation can distort apparent habitat preferences.[30]

The crested porcupine (Hystrix cristata) is Israel's largest rodent, reaching about 90 centimeters in body length and approximately 13 kilograms.[28] It is mainly nocturnal and is frequently detected by camera traps.[14] Israel also has two endangered jerboa species in sandy areas of the south and coastal plain.[28] A 2021 survey found an unexpected recovery of the Greater Egyptian Jerboa in the northern Negev, where Loess Park had been declared a reserve in 2017 to protect its habitat.[31]

The rock hyrax is not a rodent, but it is an important medium-sized herbivore and prey species. It formed a major part of the documented Arabian leopard diet and appears in woodland camera-trap surveys.[27][14] Camera monitoring also recorded an edible dormouse after more than 40 years without an Israeli observation, demonstrating the difficulty of establishing the absence of cryptic species.[14]

Bats and rodents together make up roughly two-thirds of the 131-species mammal estimate.[6] Approximately 33 bat species are reported in Israel and the West Bank—known by its original, indigenous Jewish name of Judea and Samaria—and all but one are insectivorous.[32]

Sixteen bat species are known in the southern Arava Valley, and acoustic monitoring found that 12 frequently foraged in conventional and organic date plantations. Species richness was highest in an organic plantation with complex ground vegetation, and DNA analysis confirmed consumption of date pests.[20]

A study of 29 Aleppo-pine plantations in the Judean Lowlands found greater bat richness and activity in forests with larger trees and dense shrubs. It identified mature planted forests with developed understorey as useful foraging habitat for rare and endangered species.[33] An eagle-owl diet study separately recorded Egyptian fruit bats and nine insectivorous bat species, several of which appeared to have expanded their Israeli distribution.[34]

Development has damaged natural cave roosts, leading conservationists to adapt former military outposts and other structures as substitutes.[32] Habitat loss and human disturbance remain major threats to insectivorous bats.[32]

Approximately 14 marine mammal species have been documented through observations or strandings in Israeli waters, and all are legally protected.[12] Seven may be permanent or seasonal residents that reproduce locally. The common bottlenose dolphin and short-beaked common dolphin are observed most frequently; other records include the Mediterranean monk seal, fin whale, sperm whale, Cuvier's beaked whale, Risso's dolphin, striped dolphin, rough-toothed dolphin, and orca.[12]

No approved source in the research bundle provides a current, comprehensive species checklist, and published totals differ substantially. Jewish Virtual Library pages report about 70, about 100, and 116 native mammal species.[1][2] An Encyclopedia.com survey also gives approximately 100.[8] A biodiversity report cited by The Times of Israel counted 98 species, 61 of which were considered endangered, while a Ministry of Education-hosted project gives 131.[4][6]

These figures should not be treated as measurements of the same thing. The sources provide no common census date, geographic boundary, taxonomic standard, or statement about whether marine mammals and disputed taxa are included. The available evidence therefore supports presenting the estimates side by side, not selecting a definitive total.

Much of the underlying evidence consists of regional surveys, predator-diet studies, camera-trap programs, acoustic monitoring, and long-term counts rather than a unified inventory. The rediscovery of the edible dormouse after more than four decades and the reported expansion of wolves into the Carmel illustrate how detection and distribution records can change over time.[14][24]
