Conservation status and ex situ cultivation efforts of endemic flora of the Juan Fernández Archipelago

Was realized field studies and ex situ propagation on the vascular flora of Juan Fernández Archipelago during 15 year period. To evaluate the conservation status of a total of 133 species and subspecies of vascular endemic plants I used a IUCN classification founding: 2 species extinct, 1 extinct in it natural habitat, 52 critically endangered, 37 endangered and 9 vulnerable. Thus, 73.8% are contained in a threat category; only 24 taxon can be considered to be of a lesser conservation concern. The largest threat of extinction is a reduction in individuals in local populations resulting in small, isolated populations. This habitat fragmentation and a reduction in endemic flora has also impacted endemic fauna. Besides, during this period was propagated in nurseries a total of 80 of these species and subspecies (60%). It seem clear the necessity to continue to actions conserve this particular ecosystem.
