Resumen:
Preliminary appraisal of the status of conservation of
Ferns and Lycophyta from Argentina.
The aim of this contribution is to provide a preliminary evaluation of
the endangered species of ferns and Lycophyta that inhabit in Argentina, in order to recommend strategies
for their conservation. For this purpose we considered the endemic taxa as well
as those which grow in reduced areas from neighboring countries. Categories (from 1 to 5) were assigned
according to the Plan Ear procedure, taking in account the distribution of the taxa and
their relative abundance or rarity. As a result of this study, 18 of 34 endemic
taxa of ferns and Lycophyta growing in Argentina were considered
endangered (categories 4, 4-5, 5).
The main cause of flora threatens is loss or degradation of habitats by
human activities, which affect the survival of many endemic plants from Argentina.
Integrated strategies for conservation, emphasizing in situ preservation
in their natural habitats, together with ex situ conservation by means
of spore banks are suggested.
