Upper montane grassland structure within six subranges of Serra do Mar, Southern Brazil
HoehneaThe phytosociological structure of upper montane grasslands (high altitude grasslands) was studied in six subranges of Serra do Mar. Throughout 324 (1 m2) plot samples, we identified 195 taxa out of 280 taxa previously found in a floristic survey ...
