Yatir Forest (Hebrew: יער יתיר) is a forest in Israel, located on the southern slopes of Mount Hebron, on the edge of the Negev Desert. The forest covers an area of 30,000 dunams (30 km2 (7,413 acres)), and is the largest planted forest in Israel.
The first trees were planted in 1964 by the Jewish National Fund at the initiative of Yosef Weitz. It is named after the ancient Levite city within its territory, Yatir, as written in the Old Testament: "And unto the children of Aaron the priest they gave Hebron with its suburbs, the city of refuge for the manslayer, and Libnah with its suburbs, and Yattir with its suburbs, and Eshtemoa with its suburbs" (Book of Joshua ).
Over four million trees have been planted, mostly coniferous trees - Aleppo Pine and Cypress, but also many broad leafed trees such as Atlantic Terebinth, Tamarisk, Jujube, Carob, Olive, fig, Eucalyptus and Acacia, as well as vineyards and various shrubs. Yatir Forest has changed the arid landscape of the northern Negev, despite the pessimism of many experts. It has proven to be a prime ecological instrument, halting the desertification on the heights northeast of Beersheba.
The forest is situated at a relatively high altitude (between 400 and 850 metres above sea level) in a semi-arid region with an average yearly rainfall of 300–350 mm (12–14 in) and low humidity. The ground is composed of hard lime rocks, and soft chalk rocks.
