La Casa de l'Aigua, la Trinitat Nova, Nou Barris
This temporary exhibition describes lichens, this botanical group, and introduces their uses and their role as environmental indicators. Lichens are sensitive to changes in their surroundings and are found in very different places: the city, the jungle, high mountains, on rocks, tree bark, roofs… In Collserola there are some 129 species of lichen, a few of them extremely rare. Come and find out! On loan from the Consorci del Parc Natural de Collserola.
