The predominant vegetation in the area is that of Andean
Patagonian forest with pehuenes forests, pellín oak, lenga,
cedar, raulí, coihue, morello, ñire, radal, cypress. These
last three species are characteristic of transition area
from east to west from steppe to Andean Patagonian forest.
According to the floor type and climatic factors (droughts,
winds, height, cold) the species have particular
An example is the pehuén or araucaria araucana that adapted to
the possibility of fires because this specie grow in areas
with volcanic eruptions and scarce rains. Consequently its
branches grows in the high, its bark is thick and not very
inflammable and the yolks that keep preserved reborn later
This specie is the most characteristic in the province. It's
an alive fossil because it didn't have changes in its
organism during millions of years. In turn the same one is
considered relict species. It means those species that
diminished its area growth for natural causes being located
in certain zone.
The development of these species is slow and lingering
existing trees nowadays that cohabited and fed to our
mapuches predecessors. It fruit is the seed which mature in
the autumn and is highly nutritious food. Compete for it
rodents, cachañas and human beings.
In the under story colihue canes, different types of
mushrooms, musk rose (introduced species), bushes, coirones,
grasses and flowers like amancay and mutisia grows.
The area also has several hectares of pines plantations from
the north hemisphere for forestation. This is being very
discussed if it brings more advantages (economic earnings)
or more disadvantages (erosion of the floor, loss of flora
and fauna diversity, etc). This type of forestation can be
observed when trafficking the roads of the region.
