RT Journal Article T1 Phytosociological study of the Pinus occidentalis forests in the Dominican Republic A1 Cano Carmona, Eusebio A1 Velóz Ramírez, Alberto A1 Cano Ortiz, Ana AB The article deals both with the Pinus occidentalis pine tree forests growing on high mountain limestones and siliceous substrates, and with the copses growing on serpentines in Dajabo´n (Cibao Valley), Dominican Republic. The samplings carried out in these forests reveal the occurrence of numerous endemic species and, consequently, the habitats can be considered as endemic, priority habitats of the Antilles. The article relies on some previous surveys carried out by us, Cano E, Velo´z Ramirez A, Cano-Ortiz A, Esteban FJ. (2009b). Analysis of the Pterocarpus officinalis forests in the Gran Estero (Dominican Republic). Acta Botanica Gallica 156(4):559–570, that made use of the data provided by 87 weather stations of the Dominican Republic. With the values of the Ci, Oi, Cti, etc. indexes, we make a bioclimatical proposal for Hispaniola. Our preliminary analysis of the studies published on the vegetation of the Island of Hispaniola and nearby islands, along with the samples taken by us, lead us to propose two new alliances: Ilici tuerckheimi–Pinion occidentalis and Phyllario mummularioidi–Leptogonion buchi, and three new associations: Dendropemon phycnophylli–Pinetum occidentalis, Cocotrino scopari–Pinetum occidentalis and Leptogono buchi–Pinetum occidentalis.
