Complement of comercial Forest Inventory, DST (s/d) - survey of trees 25 cm diameter at breast height (dbh) or more. In this case the mais purpose of inventory was the pre-existent natural refeneration of listed species, from recruit (below 50 cm height) to pole size (3 m height to 5 cm dbh) by linear sampling in quadrats of 2 x 2 meters.
In quadrats of 10 x 10 meters, size classes 5 cm dbh or more were observed to evaluate the occupation level and development of listed species.
Characteristics of place where the natural regeneration of listed species are developing were also observed during the data collection.
However, the emphasis of this work concerns the stocking index of listed species, a parameter that will be used in the formulation of intervention levels in the natural forest as part of a comparison with a project entitled "Ecological Management and Exploitation of Tropical Rainforest" in the same watershed area.
