The collection site was situated in a dense moist forest, consisting of a well-preserved fragment of about 200,000 m2, of the original forest that formerly occupied the plains surrounding the coastal mountain range. This forest is a campsite used by a group of Boy Scouts (Campo Escoteiro Geraldo Hugo Nunes). It is drained by small streams belonging to the
