Given the nature of the territory, we find an alternation of high alpine landscapes Pyrenees with riparian woodland on the banks of the Segre valley bottoms.
The riparian forests are deciduous and grow to banda and banda soils of watercourses that from a certain depth, tend to be saturated with water. These forests are rarely more productive because they lack water, the main factor limiting growth. Some of the most common species that we find are: poplar, ash, elm, poplar, white willow, alder ...
As we move away from the river and we climb the slopes of the mountain are the evergreens: pine, holm oak and cork oak. In the wetter areas of the forest and fresh - especially in shady areas - are established deciduous trees, of which the most important are the hazel and oak. A curious feature of our forests is the presence of chestnut trees, due to the existence of soils prone to this tree species.
Regarding the diversity of wildlife habitats, altitude, direction, composition of the substrate, microclimates, etc.. causes a considerable variety.
Mammals are the most representative:
Birds constitute the most interesting and abundant group, highlight:
In the canyons and rivers include:
Madrilla, Carp and trout
