Pinus cubensis forest syntaxa from northeastern region of Cuba

Abstract

Reyes, O.J. & Acosta Cantillo, F. Pinus cubensis forest syntaxa from northeastern region of Cuba. Lazaroa 33: 111-169 (2012). The area occupied by Pinus cubensis in the northeastern region of Cuba is studied according to the Zurich Montpellier methodology. This area with ofiolits bedrock and ferritic soils are phytosociologically very diverse, supporting three allian- ces, five suballiances and 22 associations. Of them two alliances, five suballiances and six associations are firstly described in this paper, but other combinations, as well. Bactri cubensis-Pinion cubensis characterizes the wet pines forests. It groups Panico-Pinenion cubensis with one association distributed toward the western area and Cyrillo nipensis-Pinenion cubensis with eigh associations in the eastern part. Guettardo ferrugineae-Pinion cubensis occurs in mesic and dry habitats. It is composed by Caseario crassinervis-Pinenion cubensis with three associations in the west region, Garcinio-Pinenion cu- bensis with six associations in the very extreme habitats and Dracaeno cubensis-Pinenion cubensis with three associations distributed in dry habitats. Agavo albescentis-Pinion cubensis with one association in lower areas occurs on calcareous sandstone.
