Fully grown, Atlas cedar is a large
Ecology
Atlas cedar form forests on mountainsides at 1,170 to 2,200 m (3,840 to 7,220 ft), often in pure forests, or mixed with
Currently, Morocco has the highest total surface of Atlas cedar in the world, and it forms vast forests in the humid zones of the country, around the Middle-Atlas range, the oriental and Northern High-Atlas range, and in the Western and Central Rif mountain range. The current total area is around 163,000 hectares, of which around 115,000 hectares (80%) are situated in the Middle-Atlas mountains. The species is in danger from human use, wood harvesting and fires. Data that go back to 1927 show higher number of Atlas cedars (more than 150,000 hectares) in the Middle-Atlas mountains only. The Rif mountains had one of the largest cedar forests in the past, but forests nowadays are much smaller, 15% of the total cedar forests in Morocco. Recently massive reforestation campaigns have taken place in the region of Ifrane Province.[citation needed]
In Algeria, the Atlas cedar has been in significant decline. According to data from 1966 the species inhabited 23,000 hectares, forming forests around the
Cultivation and uses
Landscape
C. atlantica is common in cultivation as an
Many of the cultivated trees have glaucous (bluish) foliage, more downy shoots, and can have more leaves in each whorl; young trees in cultivation often have more ascending branches than many cultivated C. atlantica specimens.[15]
In the
An Atlas cedar is planted at the White House South Lawn in Washington, DC. President Carter ordered a tree house built within the cedar for his daughter Amy. The wooden structure was designed by the President himself, and is self-supporting so as not to cause damage to the tree.[20]
Forestry
Cedar plantations, mainly with C. atlantica, have been established in southern France for timber production.[citation needed]
