Floristic data to support conservation in the Amazonian canga
Biota Neotropica, 2023 Abstract Canga is an environment of great natural and economic value because it harbours a considerable number of endemic species on a substrate that is rich in iron ore. In the Amazon, this open vegetation type grows on top of isolated outcrops in a dense forest matrix found in the Carajás region, in southeastern Pará.
