Abstract

The Guayana shield is one of the most important biogeographic regions of the world, with a complex matrix of ecosystems and different types of vegetation [1-4]. One of the most outstanding ecological units of the region are the granitic outcrops, also known as inselbergs (from the German Insel: island, and Berg: mountain), and locally as lajas. These rock formations have high plant species diversity, a high number of endemic species with restricted geographical distribution [2-3]. From a biogeographical approach, these geological formations are also considered as continental islands, mainly because of the ecological processes that depend to a large extent on geographic isolation [5]. This geographical isolation confers unique ecological conditions for the formation of different types of plant communities on a small spatial scale. However, since pioneering research on Guayana inselbergs vegetation types, e.g., [3-4], knowledge about plant community ecology is still limited as a basis for establishing conservation measures [6].
