Observations on the vegetation dynamics of the Capelinhos volcano (Faial Island, Azores, Portugal)
After a short overview of the pioneer vegetation on active volcanoes the eruptive history of the Capelinhos is resumed. From two maps of the vegetation regeneration on the ash fields of Capelo (2001, 2008), the results of different field work campaigns are discussed. In one part of the ashfields, th...

After a short overview of the pioneer vegetation on active volcanoes the eruptive history of the Capelinhos is resumed.
