Este trabalho tem como principal objectivo estabelecer o ponto da situação sobre o estado de conservação do património vulcanoespeleológico dos Açores. Os tubos de lava e algares vulcânicos destas ilhas têm sido sujeitos a vários tipos de distúrbios, alguns dos quais com efeitos destructivos. A presença de estructuras geológicas únicas e de grande valor patrimonial assim como a ocorrência de artrópodes cavernícolas endémicos, constituem justificações suficientes para que se estabeleçam medidas de protecção rigorosas e severas. Este trabalho sumariza os tipos de distúrbios a que têm estado sujeitas as cavidades vulcânicas açoreanas, indicando algumas soluções para medidas de conservação. Os principais tipos de distúrbio são os seguintes: deflorestação, maneio das pastagens, uso das cavidades como cemitério de gado bovino, visitação, maneio da água e lixos doméstico s e industriais.
ABSTRACT: The conservation status of the diverse vulcanospeleological patrimony of the Azores is the main subject of this paper. The lava tubes and volcanic pits from the Azores are being exposed to several types of disturbance, some of them with destructive effects. Unique geological structures and some cavernicolous endemic arthropods are enough justification to establish severe measures of conservation for such patrimony. This work focuses on the types of disturbance over the Azorean volcanic cavities and their fauna and possible ways of conservation. The main types of disturbance are: de forestation, pasture management, «cattle graveyard effect», touristic activities, water management and industrial and domestic waste.
