Résumé
Based on the geoforms of the Island Monserrat, a study of the description was carried out, distribution and revision of the status : endemics, Mexican Official Norm ECOL-059-2010 and CITES of the flora was carried out, for this study, vegetation belt transects as well as random sampling were established, registering a total of 114 plant, in 92 genera, and 38 families of vascular plants included in six growth forms ; 69 species reported are under special category, of which 34 are endemic (peninsula or islands), 2 are in the NOM and 12 in CITES list. From 66 vegetation belt transects established in the study area, some indexes were obtained, which indicate a high diversity, resulting the gullies with the highest diversity indexes and important value indexes values and also with more species under a special category compared with other geoforms, and for instant, they can be considered as critical areas. The study of Monserrat island flora permits us to have a general knowledge of its natural resources in order to carrying out a better management, in such a way, directly in its biological conservation, to permit the continuation of the biological and process in it, under of most minimum human interference conditions.
