In general, in the forest on the height of 1000 - 1100 meters dominates the broad-leaved three. Up to 1700-1800 meters dominates the beech. Other important trees are black pine with some subspecies such as Pino nero di Villetta Barrea and mountain pine.

Among typical flowers can be found the lily, violet, cyclamen, primrose, orchid and rare flowers such as Cypripedium calceolus and Iris marsica (which is only found in the Abruzzo region).
