|Alpine zone ( more than 2000m): the highest zone from 2000m, these are covered with alpine meadows with a hight number of grass species and showy flowers. like Gentiana (Gentina sp.), “Safrà bord” ( Cocus nuaifloris), Carlina ( Carlina acanthifolia subsp. Cynara) and Pulsatilla alpina (Pulsatilla aplina).|
|Sub-alpine zone ( 1500 – 2000 m): we can find pine ( Pinus uncinata) forests, well adapted specie to the hard climatic conditions . The understory consist in ginebró ( Juniperus nana), de neret( Rhododendron ferrugineum), cand boixerola ( Acrostaphylos uva-ursi).|
|Estatge montà (800 – 1500m): here we can find forest species like “faig” ( Fagus Sylvatica) in shadow side, “roures” ( Quercus pubescents) and “alzines” (Quercus ilex) in sunny slope. These three species are in the midst of pine ( Pinus sylvestris). The understory consist in “boix” ( Buxus sempervirens).|
Mammals: along the route you will be able to admire the ibex ( Rupicapra rupicapra). In summer you will find them in the shadowy and fresh zones of the high ground. In winter the ibex goes down to the sunny areas of the low ground.
Deer (Cervus elaphus) and roe deer ( Capreolus capreolus), that were extinguished long time ago, inhabit again the area thanks to the repopulation carried out during the last 50 years. Other interesting mammals you will luckily see are: marten ( Martes martes), stoat ( Mustela erminea), marmot ( Marmota marmota) which is thought to inhabit the area since few years ago, or dwarf shrew ( Suncus etruscus). One only wolf ( Canis lupus), was seen in 2003.
Birds: there is a huge variety of birds in the area. From big ones to small ones you will be able to see many of them along the route. Some of them are native species such as trencapinyes ( Loxia curvirostra), colit gris ( Oenanthe oenanthe). Other are big birds such as bearded vulture (Gypacetus barbatus), golden eagle ( Aquila chrysaetos) griffon vulture ( Gyps fulvus) and other are rare birds like the mirlo blanco ( Turdus torquatus), pito negro (Dryocopus matrius), which is the symbol of the natural reserve of Cadí – Moxeró.
Amphibious: among the amphibious we will see the Pyrenen triton ( Euproctus asper), which is considered an endemic specie in this area. Its habitat is cold and oxygenated watercourses. The red frog (Rana temporaria) sometimes can be found far from water and the totil (Alytesobsteticans), with its unmistakable sound.
