Biodiversity in Israel, the West Bank, and the Gaza Strip
Biodiversity in Israel, the West Bank, and the Gaza Strip is about the fauna and flora in the geographical region of Israel, the West Bank, and Gaza Strip. This geographical area within the region of Palestine extends from the Jordan River and Wadi Araba in the east, to the Mediterranean Sea and the Sinai desert in the west, to Lebanon in the north, and to the gulf of Aqaba, or Eilat in the south.
The area is part of the Palearctic ecozone, located in the Mediterranean Basin, whose climate supports the Mediterranean forests, woodlands, and scrub biome. This includes the ecoregions of the Eastern Mediterranean conifer-sclerophyllous-broadleaf forests and the Southern Anatolian montane conifer and deciduous forests.
There are five different geographical zones and the climate varies from semi-arid to temperate to subtropical. The region is home to a variety of plants and animals; at least 47,000 living species have been identified, with another 4,000 assumed to exist. 116 species of mammals are native to Israel, as well as 511 bird species, 97 reptile species, and seven amphibian species. There are also an estimated 2,780 plant species.
The region of Palestine with the Gaza Strip, Israel, and the West Bank are located at the eastern end of the Mediterranean Sea, traditionally called the Levante. Israel is bounded on the north by Lebanon and on the northeast by Syria. Jordan lies to the east and southeast of the West Bank and Israel; Israel and the Gaza Strip are bordered on the southwest by the Egyptian Sinai Peninsula and on the west by the Mediterranean Sea.
The region is divided into three major climate zones:
- The Mediterranean climate zone, characterized by long, hot, rainless summers and relatively short, cool, rainy winters. The rainfall may go from as much as 400mm for a year (in the south around Gaza), to 1,200mm for a year (in the northernmost end of Israel). The Mediterranean landscapes include several kinds of forest, garrigue, scrubland, marsh and savanna-like-grassland. The fauna and flora are mostly of European origin.
- The Steppe climate zone. It is a narrow strip (no wider than 60 km, and mostly, much narrower) between the Mediterranean zone and the Desert zone. The rainfall varies from 400mm for year to 200mm for year. This climate zone includes mostly low-grasslands and hardy forms of scrub. The fauna and flora are mostly of Asian and Saharan origin.
- The Desert climate zone, which is the largest climate zone of Israel, covers the country's southern half as the Negev, while the Judean Desert extends to the Dead Sea region through the West Bank and into the southern Jordan Valley. The rainfall varies between 200mm for year in the northern Galilee and 32mm for year in the southernmost tip in the Arabah valley. This dry climate zone grows scattered shrub vegetation or desert-grassland in its wetter parts. In the more arid regions, the vegetation is confined to dry riverbeds and gullies, known as wadis and in some places it is almost absent. In some of the greater valleys, desert-scrub and acacia-woodland are to be found. The fauna and flora are mostly of Saharan origin. Sudanese flora is present as well.
Alongside the major three, one microclimate zone are present:
- The Tropical (Sudanese) Microclimate by the springs of the Judean Desert. Refers mostly to Ein Gedi spring and Arugot creek. Due to the high aquifer in the region, and the steady, hot climate of the Judean desert, a tropical savanna-related flora (not rainforest, as many think) of East-African origin has established in the area of the springs. The fauna is that of the Desert zone.
The climate is determined by the location between the subtropical aridity of the Sahara and the Arabian deserts, and the subtropical humidity of the Levant or eastern Mediterranean. The climate conditions are highly variable within the area and modified locally by altitude, latitude, and the proximity to the Mediterranean sea.
