Description :
The AA. report how a pioneer liverwort, Nardia succulenta, stimulates accretion of volcanic ash, creating layers adhering to vertical bare cliffs and bridging fresh volcanic boulders, as well as creating habits that probably favour the liverworts and facilitate occupation by vascular plants. The study site is on a foot slope of the 1968 cone of the volcano Arenal, an active strato-volcano in Costa Rica.
