Inventário florestal a 100% em pequenas áreas sob manejo florestal madeireiro

Abstract

The inventory is a basic stage of the forest management in that is evaluated the composition of the forest and its potentiality for the management. The inventory to 100% has the purpose of determining the stock existent of wood logs for ends of planning of the exploration. This paper presents results of forest inventory to 100% of a wood forest management communitary project lead by Embrapa Acre in partnership with a group of small farmers of the Pedro Peixoto Colonization Project, in the State of Acre, Brazilian Amazonian region. The inventoried total area was of 206,8 ha, composed by 57 compartments with average size of 3,6 ha each one, corresponding to 48% of the total area under management of 12 small properties. Were included all the trees with DBH 3 to 50,0 cm. The results were expressed, for species, for property and for the total area in: total amount of trees (NT); amount of trees for hectare (AB); total volume (VT); volume for hectare (V); total basal area (ABsT); basal area for hectare (ABs); index of importance of the species (IND); and condition of use of the log. The results for the total area were: NT = 3.518 trees; AB = 17,01 trees.ha-1; VT = 21.667,41 m3; V = 104,77 m3.ha-1; ABsT = 1.413,77 m2; e ABs = 6,84 m2.ha-1. In the inventoried area 204 species were recognized, belonging to 136 botanical genera and 43 familiae. Was observed accentuated concentration of the dendrometric data in few species, because only five species answer for a third (33,6%) of the total IND.
