Geology

~ How was this relief formed and what evidence is there of it?

As for geological formations, the Flysch dominates the surface where the Irati forests are located, forming folds through which rocks such as limestone are interspersed with other softer ones such as clays.

Geology

What typical shapes can be found?

The Flysch dominates the surface on which the Irati forests are located and also fluvial deposits that in the current era fill the bottom of the valley.

Geology

~ What important geological formations are there in the area?

It is formed in folds that intersperse hard rocks such as limestone with softer ones such as clays.

In the west, there are geological materials from the Paleozoic, siliceous material,

Ecosystem

~ The main biotic and abiotic factors of the ecosystem

Abiotic:
-The Sierra de Ayllón predominates rocks in particular slate, shale, gneiss and quartzite. In Tejera Negra, on the other hand, slate predominates and in Montejo, shale. On the ridges, hard materials such as quartzites and slopes predominate, which are changed by fluvial phenomena, schists stand out. It is a region of Mediterranean character, characterized by its continentality and orography. The appearance is remarkable and the difference in temperatures and rainfall, there is a severe summer drought. As for temperatures, winters are rather low temperatures, which often reach -9ºC and summers are cool with temperatures of 17ºC. Typical soils are cambisols, but also ranker soils in heath and other scrub areas.

biotic:
-The vegetation is composed of a great diversity of ecological conditions and the ancient influence of the human being. In the beech there is a potential vegetation, although it is currently covered by the afforestation of Pinos; it is expected that soon there will be a replacement of the vegetation constitute the last remnants of primary beech in the Pyrenees. We are facing mixed beech and fir forests that are intact due to natural causes and historical reasons. Both are protected as integral reserves. The buffer zone is managed in three Natura 2000 contiguous Special Conservation Areas (ACE): Larra-Aztaparreta, Larrondo-Lakartxela and Roncesvalles-Selva de Irati. This area consists mainly of semi-natural beech forests, but also forests.

Ecosystem

~ What is the typical flora and fauna of this ecosystem?

Flora:
The beech is the dominant species in the Irati Forest, along with the fir, and such is its extent that it is considered the second largest forest of this type in the entire European continent. However, it is not uncommon to find among the beech trees other species such as birch, yew, holly or linden.

Fauna:
The forest shelter is the perfect habitat for several animal species, where deer, roe deer and wild boar are very numerous in terms of mammals; and looking at the sky, it is easy to spot raptors like the bearded vulture, the golden eagle and the peregrine falcon. In addition, within the avifauna, it is also worth mentioning the presence of some endangered species such as the black dick and the white-backed beak.
