La vegetación serpentinícola de lomas de La Coca, Ciudad de La Habana

The serpentine outcrop of "lomas de La Coca" is one of the more studied serpentine area in Cuba. However, its complex flora and vegetation have conduced to contradictories results. In this work we discuss previous results and propose vegetation units based on biotic and abiotic factors such as: aspect, soil type and soil deep. The primary defined vegetation types are the microphyllous semideciduos forest on serpentine soil, the thorny xeromorphic shrubwood on serpentine soil and the gallery forest. Secondary vegetation types are represented by disturbed thorny xeromorphic shrubwood on serpentine soil, grassland with shrubs and palms, disturbed gallery forest and grassland with Cecropia schreberiana.
