Forest inventory for environmental adjustment in the Santa Rita farm, located in the County of Santarém, State of Pará, Brazil

Abstract

This study was carried out aiming to identify a forest fragment and indicate tree species for recovering legal reserve and permanent conservation areas of the Santa Rita Farm. Eighteen sample plots, measuring 20 x50m each, were systematically distributed, totaling a sample area of 18.000 m². Each sample plot was divided into two levels. Level I: sub-plots of 20 x 25m, where all trees with DBH ≥ 10 cm were measured; Level II: plots of 20 x 50 m, where all trees with DAP ³ 45 cm were measured. A total of 70 tree species and 33 botanical families were identified. Families that presented higher number of species were: Lecythidaceae and Mimosaceae (7), Caesalpiniaceae and Sapotaceae (5) and Lauraceae (4). These families contributed with 40% of the species, confirming that few families represent a large part of the of tree species abundance in the Amazon high-land forests.
