The animal landscape
This uncultivated and deserted land allows the appearance of a very
varied and peculiar fauna whose animals can be classified as follows:
invertebrates, fishes, amphibians and reptiles, birds and mammals.
in the Bardenas
Among the numerous species of invertebrates there stand out two
groups: snails (12 snail species have been classified) and crabs.
In the aquatic areas you can find fishes, amphibians and reptiles.
There are eight species of fishes, but only the barbel, the nase
and the eel are autochthonous. Among the amphibians there stand
out the anuran and the newt and among the reptiles there are up
to ten species, standing out a species of water tortoise named galapago
leproso and different species of saurian and ophidians, standing
out the viper vibora hocicuda.
Birds: it is important to emphasize that the Bardenas is the area
of Navarra where most aquatic species stay in winter. As well as
vultures, golden eagles, Egyptian vultures, golden owls and other
predatory, it is important to point up the presence of steppe birds
like larks (calandria, terrera común, collalba gris) and
In the Bardenas Realses we can also find 28 different species of
mammals. Eight of them are micromammals like shrews, the dormice,
rats and nine species of bats. The remaining animals are hedgehogs,
weasels, polecats, martens, badgers, foxes, wild cats, genets, rabbits,
Iberian hares and wild boars.
The botanic interest of flora and fauna of the Bardenas
Reales is related to the climatic singularity of the Ebro hollow.
It figures in the Spanish Inventario Nacional de Hábitats
(national inventory of habitats), elaborated under the protection
of the directive 92/43, CEE, from the 21st of May.
