Resumo:The forest fires that occur every year in Mediterranean Chile have also affected the biodiversity of plant formations. At present a fragmented scenery is seen, mostly due to the changes in soil use, which have significantly reduced the habitat of the native palm trees. Chile’s Mediterranean climate is characterized in the coastal valleys and mountain ranges by a long and dry summer, zero precipitation, and constant warm winds on the coastline. This favours the recurrence and spread of forest fires. The current state of the situation is presented with respect to the forest of the endemic Chilean palm (Jubaea chilensis (Moll) Baillon, which lives in association with the Mediterranean sclerophyllous brush along the shores of Valparaiso (33°03’South-71°3’West), whose floristic entourage is highly altered by the recurring impact of the summer fires and by anthropic action in coastal microbasins. On the other hand, the regeneration of palm groves is poor due to the exploitation carried out by the local people of their edible fruits (tiny coconuts) as well as by the herbivorous fauna and domestic animals. The species has been declared in a vulnerable category, and for some 15 years the State, together with some private foundations, has been carrying out regeneration and recovery plans of this palm tree, which is the longest living and one of the southernmost in the world.
