The wide altitudinal range between Valldan (550 m) and Pedró dels quatre Batlles (2382 m) makes it possible to observe in this region many species of plants in four vegetation stages: the basal stage, the submontane stage, the subalpine stage and the montane stage.

Regarding the vegetation, we can find mountain pastures, pine forests, red pine woods, juniper scrub, buxus, and many native plants in the area.

In autumn surprises abundance of mushrooms.
