Lebanon is rich in flora, with over 3,000 species. Olive and fig trees and grapevines are abundant on lower ground, while cedar, maple, juniper, fir, cypress, valonia oak, and Aleppo pine trees occupy higher altitudes. Vegetation types range from subtropical and desert to alpine. Although hunting has killed off most wild mammals, jackals are still found in the wilder rural regions, and gazelles and rabbits are numerous in the south. Many varieties of rodents, including mice, squirrels, and gerbils, and many types of reptiles, including lizards and snakes (some of them poisonous), may be found. Thrushes, nightingales, and other songbirds are native to Lebanon; there are also partridges, pigeons, vultures, and eagles.
