The evaluation of forest composition is a very important stage of forest management. This evaluation is done through forest inventories. The objective of this work is to present the results of a 100% forest inventory make in areas of forest exploitation of small farmers under logging management, located in the municipality of Senador Guiomard, in the state of Acre, in the Brazilian Amazon. The inventoried area (206.8 ha), in which all the trees with DBH 50.0 cm were measured, revealed a total number of trees (NT) of 3,518, abundance (AB) of 17.01 trees ha-1, total volume (VT) of 21,667.41 m3, volume per hectare (V) of 104.77 m3 ha-1, total basal area (ABsT) of 1,413.77 m2 and basal area per hectare (ABs) of 6.84 m2 ha-1. A total of 204 species belonging to 136 genera and 43 botanical families were recognized in the field. The five species of highest Index of Importance of Species (IND) were: Brazil nut (Bertholletia excelsa Bonpl.), Tauari (Couratari macrosperma A.C. Sm.), Cumaru-cetim (Apuleia molaris Spruce ex Benth.), Rubber tree (Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg.) and Cumaru-ferro (Dipteryx odorata (Aubl.) Willd.). The sum of the IND of these five represents a third (33.6%) of the total IND (all species). Most of the 20 species with the highest IND are loggers of commercial use and represents for about 60% of the total IND. This study showed a significant concentration of the dendrometric elements, that is, few species unit most of the adult trees and, consequently, most of the timber volume. Entre as etapas fundamentais do manejo florestal está a avaliação da composição da floresta. Essa avaliação é feita por meio de inventários florestais. Este trabalho tem como objetivo apresentar resultados de um inventário florestal a 100% realizado em talhões de colheita de pequenas áreas sob manejo florestal madeireiro, localizadas em Senador Guiomard-AC. A área inventariada, de 206,8 ha, em que foram abordadas todas as árvores com DAP 50,0 cm, revelou um número total de árvores (NT) de 3.518, abundância (AB) de 17,01 árvores ha-1, volume total (VT) de 21.667,41 m3, volume por hectare (V) de 104,77 m3 ha-1, área basal total (ABsT) de 1.413,77 m2 e área basal por hectare (ABs) de 6,84 m2 ha-1. Foram reconhecidas 204 espécies, pertencentes a 136 gêneros e a 43 famílias botânicas. As cinco espécies de maior Índice de Importância da Espécie (IND) foram: Castanheira (Bertholletia excelsa Bonpl.), Tauari (Couratari macrosperma A.C. Sm.), Cumaru-cetim (Apuleia molaris Spruce ex Benth.), Seringueira (Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg.) e Cumaru-ferro (Dipteryx odorata (Aubl.) Willd.). Estas cinco espécies representaram um terço (33,6%) do IND total. A maioria das 20 espécies com maior IND são madeireiras de uso comercial e responderam por cerca de 60% do IND total. Os resultados mostraram expressiva concentração dos elementos dendrométricos, ou seja, poucas espécies reúnem a maior parte das árvores adultas e, conseqüentemente, a maior parte do volume madeireiro.

Inappropriate soil management practices are one of most important constraints on cashew production in Northeast Brazil. This work aimed to evaluate the changes in soil C and N dynamics caused by different management of cover plants (spontaneous or leguminous) in dwarf cashew culture in Northeast Brazil. The evaluated management systems for control of spontaneous vegetation included: disc harrowing (DH), mechanical mowing (MeM), manual mowing (MaM), leguminous cover crop (LEG), leguminous cover crop + mulch of Carnaúba palm (LEG + m), and application of herbicide (HERB). The floristic composition, plant density, biomass production, and the nutrient content of the spontaneous plants that grew between cashew rows were evaluated. Total soil C and N, mineral- and organic-N, light organic matter fraction, microbial biomass, CO2-C emission rates and humic substances were determined. HERB treatment promoted a substantial change in the floristic composition of spontaneous species. Richness index was highest in the LEG treatment in the fifth year of the experiment. Dry matter amount of spontaneous plants was quite similar in MeM, MaM, LEG, and LEG + m treatments, with average values of 2245 kg ha−1. DH and HERB treatments reduced dry matter by 69 and 80%, respectively. The MeM system resulted in the highest soil C stock, whereas the DH treatment tended to intensify the mineralization process of soil organic matter due to soil disturbance. LEG treatment resulted in the highest mineral-N contents. Our results suggest that the maintenance of soil organic C levels in DH and MeM treatments is strongly dependent on maintenance of light organic matter levels. Soil from treatments which favored input of organic matter (e.g., LEG, LEG + m and HERB) presented greater C-humic/C-fulvic acids ratio, indicating the predominance of humic acids. Our findings reinforce that cover plants (e.g., spontaneous vegetation and leguminous species) play an important environmental role, contributing to organic matter and nutrient cycling in the soil. Management systems that promote soil covering and the use of leguminous species increased soil organic matter stocks.
