Pine cembro

The pine cembro (Pinus will cembra) , also called pine of the Alps , is the tree symbolic system of the high mountain, because it develops between 1  700 and 2  400 meters of altitude, where the winters are very long and the rigorous temperatures.

Other common nouns: Pine cembrot, arol, arole, arolle, arve, auvier, pinarolle, tinier.

Geographical distribution

Species typically of the subalpine stage. One meets it on the totality of the alpine arc.

Description

  • Its port is pyramidal or oval, broad at the base.
  • the branches are green-bluish, summer like winter, covers of a pubescence.
  • the Feuille S are needles gathered by 5. They are with triangular section a length from 5 to 12 centimetres.
  • the bud S are cylindrical and pointed. The cones ovoid, squat are purplished and pruineux, and fall without opening the first year.
  • the bark smooth scaly young person then. It contains resiniferous cells.

Biological characters

Adult it measures up to 25 meters and its life expectancy is 600 years. Its growth is very slow and it takes him thirty years to become a shrub of 1,30 meter height.

Its wood, easy to work, is used for the construction of pieces of furniture, which consequently protect their contents from the insects.

Each one of its cones, can contain a hundred pine cones which constitute a true feast for the bird called Casse-noix moucheté. This one extracted seeds the cones of the pine which it breaks with its nozzle and hides under ground in several hundreds of hiding places disseminated on its territory of reproduction to constitute reserves.

However, in spite of the extraordinary memory of the bird which is able to memorize the site of each one of its reserves, it ends up forgetting the three quarters of its hiding-places, which will allow a few months later many seeds to germinate to give rise to new pines.

Ecological requirements

The reproduction of the pine cembro is ensured by a bird, the Casse-noix moucheté. In the Natural reserve of the Plan of Tueda, one of vastest forests of pine cembro of the Alps of North pushes the, with 100 hectares of cembraie pure and 150 hectares of a mixed settlement associating the pine cembro with the spruce.
