AB Pine forest in the Canary Islands is mainly dominated by Pinus canariensis, theonly species in this genus endemic in oceanic islands. This forest is the most affected byfires in the Archipelago, however adults of P. canariensis are highly adapted to fire. Keyprocessesin ecosystem maintenance such as long term post-fire regeneration dynamic andecosystem recovery have not been deeply studied. The IEBG had developed in recent yearsseveral researches about dynamic of Canarian pine forest under fire regimens in Tenerife,La Palma and Gran Canaria. Despite adaptations to fire, sexual regeneration of P. canariensisnot dependent on fire and appears to be adapted rather to phenomena involving thedisappearance of adults, such as high winds or colonization of new habitats. Fires alsochange understory conditions allowing a progressive inflow of herbaceous species thatwere not part of the ecosystem before the fire. In less than 10 years, these species are displacedby ecosystem mature vegetation. The invertebrate fauna dependent on the Canarianpine mulch is also affected by fires, wich reduces it richness, abundance and composition.However, and because to the overall ecosystem is adapted to this type of disturbance,these effects are mitigated also in less than 10 years.
