THUJA (TETRACLINIS ARTICULATA)
This resinous species is widespread because it can colonise any
substrata. It is also necessary to note that Thuja ecosystems
are quickly restored after disturbances because of the species
high resilience (Benabid, 2000).
The Thuja forests form big mosaics of mono specific formation.
This species is essentially confined to the south western Mediterranean
region. It is in this region that the species constitutes the
most extended populations and the most varied. It is a species
that undergoes natural regeneration if the ecological conditions
are favourable and
if well managed as a coppice forest. This type of forests is generally
managed as coppice. The plant has an important social and economic
value. Its wood is much appreciated for local crafts.
The hard wood of the aromatic species
of Thuja is used by the artisanal and local handicraft industry.
For this reason the species faces high anthropic pressure. In
the study areas where the climate becomes more arid with increasing
distance to the continent, the Thuja is replaced by Juniper
(Juniperus phoenicea). As a consequence of the efforts
that have been undertaken for the stabilisation of the dunes,regular
plantations of Eucalyptus gomphocephala and Acacia
species are widespread in the coastal zone.
