Diversity of Chilean halophytes: distribution, origin and habit

Abstract

Halophyte species are recognized for their ability to survive in salty environments. However, this condition greatly varies
among plant taxons, difficulting their proper classification. Currently, the eHALOPH database registers halophyte species
from around the world, under a single salinity criterion. In the present study, the first list of halophyte species present in
Chile made from eHALOPH is presented. Results indicate a diversity of 138 species, distributed in 31 families. Over 80%
of species are herbaceous and nearly 55% are exotic. The largest richness was found in Coquimbo and Valparaíso regions,
and the lowest in the insular territory. These results are a first approximation to halophyte diversity in Chile. At the same
time, it poses a challenge to advance in their recognition in order to propose strategies for their conservation and use.
