The Bible (Deuteronomy 8:8) describes the country as "a land of wheat and barley, of vines and fig trees and pomegranates, a land of olive trees and honey." The original forests, evergreen and maquis, have largely been destroyed, but some 200 million new trees have been planted during this century, in a major reforestation program. Vegetation cover is thin except in the coastal plain, where conditions are favorable to the cultivation of citrus fruit, and in the Jordan Valley with its plantations of tropical fruit. Among surviving animals, jackals and hyenas remain fairly numerous. There are wild boar in the Lake Hula region. With the growth of vegetation and water supplies, bird life and deer have increased.
