Traditional management maintains subtropical highland grasslands in southern Brazil
Tree species diversity and community structure, ecological traits, phytogeographic history and conservation status in an upper montane araucaria forest remnant.
Abundance and species composition of trees are affected by land management and araucaria crown influence.
Nurse plants play a key role in *restinga* environments and their presence is critical to maintain ecosystem diversity and function.
Most species showed an aggregated distribution. Both association and dissociation patterns occurred among species leading to distinct forest patches.'
Most of the species surveyed are widely distributed across southern Brazilian vegetation formations. A large proportion of species belonged to the western seasonal contingent.
