GRACIOSA ISLAND

 
       
  General Description   Graciosa is the most northerly of the Central Group of islands in the Azores Archipelago and, with an area of only 60.7 km2 and 38.9 km of coastline, it constitutes the second smallest island in the region (after Corvo). Graciosa is also the flattest of the islands, with its highest point reaching 405 m. With a maximum length of 12.6 km and maximum width of 7.0 km, the island extends along a NW-SE orientation and is distanced by 56.8 km from Ponta da Serreta, on the Island of Terceira and 36.5 km from Fajã do João Dias, on the Island of São Jorge.

Presently, Graciosa has approximately 4,800 inhabitants (estimation for 2004 was 4,777 inhabitants), distributed throughout the municipality of Santa Cruz da Graciosa’s 4 parishes: Guadalupe, Luz, Praia and Santa Cruz. Graciosa’s population continues to be strongly linked to the primary sector as a principal source of income and as a secondary activity.
The proposed Biosphere Reserve displays the following zonation:
• Core Areas: 4 non-contiguous Core Areas are defined (Ponta Branca, Ilhéu de Baixo Islets–Restinga, Caldeira and Vila Islet). These constitute sites classified under the European Union’s Natura 2000 Network, marine resource special protection areas and the Caldeira Natural Regional Monument of Graciosa Island.
• Buffer Zone: The Buffer Zones that surround the Core Areas “Ilhéu de Baixo Islets–Restinga” and “Caldeira” unite along a NW-SE axis, at the exterior SE flank of the “Caldeira” cone. The remaining two zones surround the Core Areas “Ponta Branca” and “Vila Islet”. The Buffer Zones consist of public and private lands or marine areas, with land/sea-use practices according to several different territory and activity planning schemes, on a national, regional and local level.
• Transition Area: The Transition Area encompasses both terrestrial and marine zones and surrounds the entire Core and Buffer Zones. The Transition Area includes urban and urbanizable areas, in public and private lands, with land/sea-use practices in accordance to several territorial and activity planning measures.
