Endemic Hemicryptophyte Grasslands of the High Mountains of the Caribbean

Although there are numerous studies on the floristic composition of Andean and Caribbean grasslands, limited information from a phytosociological point view. This work therefore aims to highlight differences in this important vegetation type these two biodiversity hotspots gain better understanding their vegetational richness. The grasslands (Ecuador) island Hispaniola is also studied. reason for comparative analysis territories tropical character bioclimatic similarities. Peruvian Colombian based knowledge literature, our inventories Hispaniola, works Peguero.
