Thuriferous juniper (Juniperus thurifera)
in Morocco
The thuriferous juniper
and the Scientific Research
For several years, the thuriferous juniper
is the subject of varied researches, led in France, in Spain and in Morocco.
26 and 27 September 1997, the first International Conference about this species
has been organized at Marignac (Haute-Garonne, France), at the bottom of the
Mountain of Rie stand in Pyrenees.
At the Terrestrial Ecology Laboratory of the University Paul Sabatier of Toulouse (France), researches mainly concern:
- the study of tree rings, so as to determine
the sensitivity of this species to the climate (dendroecology), as well as the
age of these pluri-secular trees, perhaps millennial (Valérie
Bertaudière).

- the study of the soil - vegetation interactions, to show the effect of the degradation on the erosion of soils.
- the study of the biomass (with non-destructive method), the mineral composition and the carbon stock of these high mountain environments, so as to deduce some trophic potentialities (Nicolas Montès).
In Morocco, in addition to that biomass
and mineral composition studies, researches are also led on problems of regeneration
of this species: indeed, seeds are often parasited (photograph hereafter). Those
healthy seeds germinate only under the shelter of the tree, but grazing and
summer dryness eliminate the rare plantlets.

In Spain, main research themes concern the bryophytic flora on thuriferous juniper (moss and lichens), the fauna associated with this species, the germination and the vegetative reproduction by cuttage.
