A survey on palynological studies realized in the National Forest of
Caxiuana, state of Pará, Brazil, is given. These studies comprise two main
issues. Firstly, the morphology of actual pollen grains and spores was
described and illustrated. Secondly, pollen grain and spore deposition in a
savannah-like area and in “terra-preta-de-índio” (Indian black soil) of the
National Forest of Caxiuana were analyzed. Joining this knowledge, local,
regional and environmental changes and oscillation could be related to recent
vegetational fluctuations and to human/Indian activities realized in the region
of Caxiuana.
