The Serra da
Estrela is full of special landscapes and places. The location of
this cache is one of those places, an area where we can find a
beatiful spot of Pinus Sylvestris L.
Pinus
Sylvestris L. it´s one of two species of pine that botanists
have no doubt in classify as indigenous in the continental
Portugal. The other one is the Pinus pinea L.
The best known
species of pine in Portugal, the rough-pine (Pinus Pinaster
Aiton), is still not consensus among experts, whether it is
indigenous in Portugal.
According to
scientific studies, more specifically based on results of pollen
analyses, the top of Serra da Estrela, have been covered by forests
of Pinus sylvestris L., Betula sp. and Taxus
baccata L., after the retreat of the glaciers of the last
glacial period.
However, at about
10.000 years ago, this specie disappeared from Serra da Estrela, so
that there are currently in the Serra da Estrela belong to
non-indigenous varieties, which have been introduced by the State
Forestry Services.
Currently, there
are some indications that the specie it´s spreading without human
direct intervention. |
