The flora of El Pallars Sobirà, its natural areas, are similar to other parts of the Catalan high mountain, as the fauna commonly associated to the county. Those are species perfectly adapted to the cold, as for instance, the ptarmigan, the chamois and the ermine, which belong to the Alpine stage.
Further down the mountainside, on the sub Alpine stage, one can find species that belong to the forest (some of them threatened with extinction), such as the capercaillie, the Pyrenean little owl, a variety of woodpeckers, the roe deer, the fallow deer and some other more that can be seen on a lucky day. As a matter of fact, the biggest population of capercaillie of the state is found in this county due to the large amount of Scotch pine, and fir forestlands. Many regions in these forests have sheltered as well the brown bears of the Pyrenean mountain range.
On the sunny slopes, the established fauna are the partridge, the hare, the wild boar and the deer, among others. These are usually found among the laburnum, the rhododendron and other bushes, the same habitat is shared with an important amount of bird species and flesh eating mammals of middle size.
On the mountain stage, very close to the areas where people still lives, the deciduous forests and the winter grazes and meadows- becoming more and more scarce every season_ will be the typical habitat for species from the centre of Europe, such as the the bullfinch and the yellow-hammer, among others.
In the rivers and clean water lakes (very abundant and characteristic from El Pallars), the common trout, the dipper and the otter still subsist.
Finally, the population of predatory birds, such as the vulture, the indigenous bearded vulture and the golden eagle will fly above the summits searching some food.
