Cedrus in Himachal Pradesh
The species of Cedrus found in Himachal Pradesh is Cedrus deodara
Cedrus deodara has been given the status of State Plant
Cedrus deodara: Etymology
The botanical name, which is also the English common name,
derives from the Sanskrit term devadāru, which means "wood of
the gods", a compound of deva "god" and dāru "wood, tree".
Cedrus deodara: Habitat and Ecology
Cedrus deodara is a high mountain tree, but it occurs in a wide range of habitats in the Himalaya.
It grows in a belt at elevations between 17,00 m and 3,000 m a.s.l. in the western part of its range
and between 1,300 m and 3,300 m in the eastern part, where the climate is less dry.
At higher elevations it forms a coniferous forest belt with, among other species, Abies pindrow, A.
spectabilis in Nepal, Pinus wallichiana, Picea smithiana, and Cupressus torulosa, but forms often
also pure stands.
At the highest limits of Cedrus, Juniperus squamata is the only accompanying conifer species.
At lower elevations first Quercus spp., then Aesculus indica, Betula sp., Corylus jaquemontii, Acer
spp., Prunus spp. and shrubs mark the transition towards a broad-leaved forest.
Systems: Terrestrial
Cedrus deodara: Physical description
Leaf: Evergreen needles, dark green but may have some silvery bloom
giving them a blue-green color; 1 to 2 inches long, sharp pointed;
occur singly on new growth and than later on spur shoots; remaining
on the tree for 3 to 6 years.
Cedrus deodara: Physical description
Flower: Species is monoecious; male cones 2 to 3 inches long on the
lower parts of crown; female cones erect, purplish, occur on upper
portions of crown.
Cedrus deodara: Physical description
Fruit: Upright cones, 3 to 4 inches long and 3 inches across;
deciduous scales; initially green and purplish, then later turning a
reddish brown when mature, usually resinous.
Cedrus deodara: Physical description
Twig: Slender, with numerous short spur shoots, branches droop with
age; buds are very small and round.
Cedrus deodara: Physical description
Bark: Initially smooth and gray-brown, later developing short furrows
with scaly ridge tops.
Cedrus deodara: Physical description
Form: Young trees have a broad pyramidal crown that becomes wider
with age; branch tips and leaders droop and have a fine texture. In
the landscape it can reach 80 feet tall but becomes much taller in its
native range.
Cedrus deodara: Uses
It is widely grown as an ornamental tree, often planted in parks and large gardens for its
drooping foliage.
Cedrus deodara: Uses
It is used as construction material
Deodar is in great demand as building material because of its durability, rot-resistant character
and fine, close grain, which is capable of taking a high polish.
Its historical use to construct religious temples and in landscaping around temples is well
recorded.
Its rot-resistant character also makes it an ideal wood for constructing the well-known houseboats
of Srinagar, Kashmir.
In Pakistan and India, during the British colonial period, deodar wood was used extensively for
construction of barracks, public buildings, bridges, canals and railway cars.
Despite its durability, it is not a strong timber, and its brittle nature makes it unsuitable for
delicate work where strength is required, such as chair-making.
Cedrus deodara: Uses
Herbal Ayurveda- The use of C. deodara in Ayurvedic medicines
is well recorded. The inner wood is aromatic and used to make
incense. Inner wood is distilled into essential oil. As insects avoid
this tree, the essential oil is used as insect repellent on the feet of
horses, cattle and camels. It also has anti-fungal properties and
has some potential for control of fungal deterioration of spices
during storage. The outer bark and stem are astringent. In
Himachal people suffering from asthma or other respiratory
problems are advised to sit under a Deodar tree early in the
morning.
Cedrus deodara: Threats
Intensive logging (legal and illegal) in some parts of its range (e.g.
Afghanistan) may pose a localized threat. Deforestation and
conversion of forests for agriculture may also pose local threats in
some parts of Pakistan and India.
Cedrus deodara: Conclusion
Cedrus deodara may now be categorised as Least Concerned but if intensive
logging continues the day will not be far when it will become extinct from the face
of the earth.
