[4] Amazon campinas are defined as open forest on sandy soil where sunlight can reach the ground.
[8] One author distinguishes between a campina shrubland and scrubby campinarana forest, both of which grow on white sand soil typically associated with large stream gullies.
[10] A Brazilian forestry institute defines campina as a type of terrestrial biome consisting of open fields, completely denuded of trees.
[12] A description of the Uatumã Sustainable Development Reserve states that campinas and campinaranas are abundant but very fragile, mainly due to their sandy soil.
The campinas have tourist potential due to their scenic beauty and large numbers of bromeliads and orchids.
