The wildlife of Israel includes the flora and fauna of Israel, which is extremely diverse due to the country's location between the temperate and the tropical zones, bordering the Mediterranean Sea in the west and the desert in the east. Species such as the Syrian Brown Bear and the Arabian ostrich have become extinct due to hunting and loss of habitat.[1] As of May 2007, 190 nature reserves have been established in Israel.[2]

Israel contains a variety of mammals due to its geographical and climatic diversity. For many of the mammals, Israel is the border of their territory. The territories of species which originate in the Palearctic generally stop at the deserts and those who originate from the African deserts usually stop at the Mediterranean coasts. Most of the mammals in Israel are of a Palearctic origin and about tenth of the mammals are endemic to its general area. The Land of Israel once contained a variety of mammals, however in recent times many mammals such as the European Water Vole, the Cheetah and the Caucasian Squirrel went locally extinct. In the modern age many mammal populations such as the Arabian Leopard and the Sand Cat are in a high risk of extinction. In total there are 57 species of mammals which are endangered (as of 2002) out of the total 104 species.[3] The largest living predator in Israel is the Striped Hyena and its population too is endangered. There are 33 species of bats in Israel (as of 2002), the most species out of the ten mammalian orders currently in Israel, most of which are insect-eaters.[4]
Various animal species are now extinct due to unchecked hunting under Ottoman rule and to a lesser extent under British Mandate rule, due to a non-enforcement of hunting laws. By the beginning of the 20th century, the White Oryx, the Syrian Brown Bear, the Cheetah, and the Nile Crocodile became extinct in the region. Modern hunting laws prohibit all hunting of mammals, birds, reptiles and amphibians, except those considered pests and specific animals in hunting seasons.
Rapid urbanization as well as overforestation (planting many dense Eucalyptus and Pine forests) have caused the destruction of many natural habitats. One of the most famous examples of habitats destroyed is the drying of swamps including the Hula lake which caused the local extinction of the European Water Vole and jungle cat .
Another distinguished cause of endangerment is the past use of DDT and other chemicals which has hurt all of the birds of prey populations as well as the bat population (mainly Microchiroptera) which were also killed by human made lighting in the caves due to the suspicion that fruit-eating bats were harming local crops.
A few mammals that have gone locally extinct are being reintroduced such as the Persian Fallow Deer[5] and the Roe Deer.[6][7]
Israel has roughly 100 species of reptiles, of which almost a third live in its northern areas. The extinction rate among reptiles has been relatively tame, reptiles that went extinct in the beginning of the 20th century include the Nile Crocodile, the European Pond Turtle and the Levant Viper.[8]
The number of amphibians in Israel has decreased dramatically since the last century mainly due to the drying of various swamps and wetlands by early settlers. The Israel painted frog is now extinct. There are currently six species of amphibians in Israel, only one of which is not endangered.[3]
The amphibians of Israel include four from the order Anura (the Marsh Frog, Hyla savignyi, the Green Toad and the Pelobates syriacus (Eastern Spadefoot Toad) and two from the order Urodela (the Fire Salamander and the Banded Newt). The Banded Newt and the Eastern Spadefoot Toad are critically endangered.[4][9]
The European Green Toad is the most widespread amphibian in Israel, living across nearly the entire Mediterranean shore. While the toad is usually limited to areas with a constant supply of water, populations have begun to spread into drier places. Even though it has relative great range in Israel, a 55% decrease has been noted in active spawning sites, mainly due to destruction of habitats, water contamination and habitats being split by roads or train tracks. The population currently numbers at a few thousands.[9]
The Eastern Spadefoot Toad (Pelobates syriacus syriacus or Pelobates transcaucasicus), also called Syrian Spadefoot Toad, is critically endangered and is locally extinct in Jordan. The Spadefoot lives in the Israeli coastal plains, north of Holon and Ashdod. Only a few hundred adult toads remain in Israel due to splitting of habitats and the species' loyalty to their spawning spots. The Spadefoot is a protected species by law.[4][9][10]
The Banded Newt (Triturus vittatus vittatus) lives mainly in the northern areas of Israel, especially in the Galilee area, mostly in vernal pools. The coastal shores near Ashkelon are the southern border for its global population. Small populations in more southern areas disappeared due to water contamination. They are inactive during the summer, staying underground in estivation, and even in winter they are only active at night. The newts have slightly different breeding seasons depending on location, ranging from January–February in the coastal plains to February–March in the Galilee.[11] The banded newt is critically endangered in Israel (only 5% of the 1950s population remains) and is thus a protected species.[11][12][13]
Fire Salamanders (Salamandra salamandra salamandra or S. s. infraimmacullata) reside near the Mediterranean shores and are the least widespread of the amphibians of Israel. The salamanders have three distinct populations (in Tel Dan, Mount Carmel and the Galilee). Compared to European populations, the adults have especially long legs and fingers and a more rounded head. The local populations differ in size (Tel Dan salamanders are much smaller), arrangement of spots on the skin and colour (ranging from orange to yellow), in mating habits and times, as well as activity times (Tel Dan salamanders are active throughout most of the year because of their proximity to water). The populations are relatively stable. Nevertheless, they are an endangered species in Israel and one of the three amphibians to be a protected species.[9][11][14]
Marsh Frogs (Rana ridibunda or Pelophylax ridibundus) live almost exclusively near stable water pools or winter pools, mainly in north and central Israel. The frogs are active even during the summer and sometimes during the day. The frogs are lighter and slightly smaller than in other countries.[11]
Hyla savignyi (also Hyla arborea or "Tree Frog") is the most abundant amphibian in Israel, though its available breeding sites have decreased and it is considered "vulnerable." Populations reside in the Northern Negev and north of it, though they once reached as far as the Dead sea. The population is estimated at a few thousands.[9][15]
Israel is currently home to about 1,728 species of fish, 410 of which in the Mediterranean and 1,270 in the Red Sea. The rest are cultivated or wild freshwater fish. The fish population has decline drastically and endemic species such as the Yarkon bleak and Nemacheilus dori have become endangered. Acanthobrama hulensis became extinct in the 1970s following a decline in population after the drying of the Hula lake.[16]
Since Israel is on a widely-travelled path from Europe and Western Asia to Africa and vice-versa, birds can be seen in Israel in great numbers. However the number of raptors has been decreasing greatly due to its prey becoming endangered or extinct as well as massive poisoning of some prey. There are roughly 511 species of bird in Israel in different seasons. About a fifth of the nesting birds are endangered (39 out of 206).[3]
Israel has about 30,000 invertebrates, of which about 22,500 are insects and 3,900 are non-insect arthropods. Among the invertebrates there is a wide variety of molluscs, of which about 230 are terrestrial, 850 are of the Mediterranean and 1,120 are of the Red Sea. The insects of Israel belong to various ecological zones, but mainly to the Mediterranean. There are insects belonging to roughly 27 orders in Israel, out of about 29 worldwide.[17]
Israel contains many invasive species brought by man, including scores of molluscs which usually live around gardens and greenhouses but also in natural habitats of native molluscs. As of 2008, over 220 species of invasive insects have been identified, some of them considered pests. The situation is little better with vertebrates, as a 2004 report reported that there are two mammalian invasive species (the Coypu and Indian palm squirrel), one fish species (mosquito fish), two reptilian species (the Red-eared pond slider and the Roughtail gecko) as well as 18 bird species. There are no amphibian invasive species, most likely due to the fact there are no suitable habitats for such.[18][19]
There are 2,867 known species of plants found in Israel.[20] Of these, at least 253 species are introduced and non-native. The coastal plain and Sharon regions are especially rich in endemic species.
