dataset from: Fockink et al. The role of nurse trees in the plant community of park grassland: a case study in Southern Brazil. <i>Applied Vegetation Science.</i>

We investigated the facilitation of three nurse tree species typical of park grassland (<i>Prosopis affinis</i>, <i>Prosopis nigra </i>and <i>Aspidosperma quebracho-blanco</i>)<i> </i>on the composition and structure of the plant community and the mechanisms through which these species facilitate the establishment of other species under their canopies.File list:<b>dendro_variables.csv</b>Dataset containing dendrometric variables of nurse trees: height (m); stem height (m) and crown diameter (m).<b>floristic_data.csv</b>Dataset containing woody and herbaceous species recorded per plot, sampled under the canopy of nurse trees (under tree) and in paired open areas (open area).<b>env_variables.csv</b>Dataset containing environmental variables recorded under the canopy of nurse trees (under tree) and in paired open areas (open area). The results include the following variables:abund_woody – Abundance of woody regenerantsrichness_woody – Richness of woody regenerantsabund_herbs – Abundance of herbaceous speciesrichness_herbs – Richness of herbaceous speciessoil_cover_native – Native herbaceous cover (%)soil_cover_exotic – Exotic herbaceous cover (%)exposed_soil – Exposed soil (%)litter_cover – Litter cover (%)litter_depht – Litter depth (cm)LAI – Leaf Area Index<b>relative_interaction_index_RII.csv</b>Dataset containing the Relative Interaction Index (RII) calculated for each species, along with their classification based on the type of facilitation. The classifications are as follows: Nfc = non-facilitated, Fc = facilitated, and N = neutral.
