  • PF: for the habitat types that can have a non-priority as well as a priority form (6210, 7130, 9430) enter "X" in the column PF to indicate the priority form.
  • NP: in case that a habitat type no longer exists in the site enter: x (optional)
  • Cover: decimal values can be entered
  • Caves: for habitat types 8310, 8330 (caves) enter the number of caves if estimated surface is not available.
  • Data quality: G = 'Good' (e.g. based on surveys); M = 'Moderate' (e.g. based on partial data with some extrapolation); P = 'Poor' (e.g. rough estimation)

Habitat class % Cover
N0183.00
N2217.00

Total Habitat Cover

Other Site Characteristics

Isolotto disabitato ubicato a sud dell'Isola di S. Antioco costituito da rocce vulcaniche di età terziaria che presentano particolare interesse per le morfologie sottomarine e per l'articolazione delle forme relative al vulcanismo del Sulcis.

4.2 Quality and importance

La distanza dalla terraferma unitamente alle specificità floristiche recentemente studiate costituiscono uno dei motivi per la conservazione e tutela del sito. Inoltre, è una zona di rilevante valore faunistico per la presenza delle specie elencate nell'Allegato I della direttiva 79/409/CEE. Locus classico di due specie botaniche quali Hyoseris taurina Martinoli e Silene martinolii Bocchieri et Mulas.
