Evaluación preliminar del grado de amenaza de los Helechos y Licofitas de Argentina

Abstract

 El objetivo de esta contribución es realizar una evaluación preliminar del grado de amenaza de los helechos y Lycophyta que crecen en Argentina, con el fin de proponer estrategias para su conservación. Para ello se tuvieron en cuenta los taxa endémicos así como aquellos que crecen en áreas reducidas de países limítrofes. Las categorías (1 a 5) fueron asignadas de acuerdo con las propuestas por el PlanEar, considerando el área de distribución y su abundancia relativa o rareza. Como resultado de este estudio, 18 taxa de helechos y Lycophyta de Argentina fueron considerados amenazados (categorías 4, 4-5, 5), de un total de 34 taxa endémicos. La principal causa de amenaza de la flora en esta región es la pérdida o degradación del hábitat por las actividades humanas, poniendo en riesgo la supervivencia de muchos taxa endémicos. Se sugieren estrategias combinadas de conservación, con énfasis en la protección in situ junto con la conservación ex situ en bancos de esporas.
