More than one-tenth of the country is forested. The most extensive forest is found on the mountain slopes rising from the Caspian Sea, with stands of
oak,
ash,
elm,
cypress, and other valuable trees. On the plateau proper, areas of scrub oak appear on the best-watered mountain slopes, and villagers cultivate orchards and grow the plane tree, poplar,
willow,
walnut,
beech,
maple, and
mulberry. Wild
plants and
shrubs spring from the barren land in the spring and afford pasturage, but the summer sun burns them away. According to
FAO reports, the major types of forests that exist in Iran and their respective areas are: •
Caspian forests of the northern districts (33,000 km2) •
Limestone mountainous forests in the northeastern districts (
Juniperus forests, 13,000 km2) •
Pistachio forests in the eastern, southern and southeastern districts (26,000 km2) •
Oak forests in the central and western districts (100,000 km2) •
Shrubs of the
Dasht-e Kavir districts in the central and northeastern part of the country (10,000 km2) •
Sub-tropical forests of the southern coast (5,000 km2) like the
Hara forests. ==Fauna==
