ALMEIDA, Larissa Santos de et al. Phytosociology and multiple use of forest species in a logged forest in Santo Antonio community, municipality of Santarém, Pará state. Acta Amaz. [online]. 2012, vol.42, n.2, pp. 185-194. ISSN 0044-5967.  http://dx.doi.org/10.1590/S0044-59672012000200002.

The forest potential was evaluated in the logged area in the Moju I and II Settlement, located at a secondary road near km 124 of the BR 163 highway, in the municipality of Santarém, Brazilian Amazonia. Twelve 50 m x 200 m plots were established in a 12 ha sample area, in which all trees CPH (circumference 1.3 m above ground) > 157.5 cm were recorded; twelve 50 m x 50 m subplots in which individuals 94.2 cm ≤ CAP < 157.1 cm were recorded; and twelve 50 m x 25 m subplots for measuring individuals 31.4 cm ≤ CAP < 94.2 cm. A total of 1227 trees from 175 species and 38 families were recorded in the forest sample. Higher number of species was found in Fabaceae and genus Inga was the richest. Diversity Shannon index (H') was 4.39 and Evenness index (J) was 0,85. The analysis of VIA showed that remain forest keeps a stock of timber and non-timber potential species for using by the community. Carapa guianensis, Caryocar villosum, Brosimum parinarioides, Aniba canellila, Bowdichia virgilioides and Andira surinamensis can be suggested to be removed from the timber harvesting list, thus improving community economic return. Manilkara huberi and Carapa guianensis were the species with more expressive timber and non-timber uses, respectively, according to the present market and the potential of known uses; so it will be very interesting that these characteristics can be taking into consideration during the elaboration of plans and management of the forest.
