Vegetation plot and trait data from phonolitic and basaltic rocks on La Palma (Canary Islands, Spain)

Geodiversity promotes biodiversity by increasing habitat heterogeneity. In times of a global decline, data about diversity on such geological elements gains importance, also regarding conservation and restoration. the Canary Islands, phonolitic rocks are volcanic origin that represent additional for species. southern part island La Palma, phonolite can be encountered in matrices young lava. We provide biotic abiotic records from 60 plots 2 m × m, sampled neighbouring basaltic outcrops at four different sites cover wide environmental gradient. The recorded parameters were species abundances (percentage cover), plant individuals' frequency (number individuals per plot species), growth height (in cm), canopy diameter cm). Additionally, lichen cover) was estimated. To describe site specific characteristics, we surface dynamics (3D rock surface), aspect, inclination. This set covers vegetation trait comparing phonolites basalts Palma. It used biogeography, ecology sciences to help support fundamental research related insular endemism, identify priority areas protection preservation Islands.
