This study was carried out to evaluate the dynamics of sward condition and botanical composition of a mixed pasture of marandugrass (Brachiaria brizantha cv. Marandu), forage peanut (Arachis pintoi cv. Mandobi) and tropical kudzu (Pueraria phaseoloides), rotationally stocked at four daily forage allowance levels (6.6, 10.3, 14.3 and 17.9% of live weight). Sward condition was characterized in each stocking cycle by measuring pre- and post-grazing sward height, forage mass and percentage of bare ground. Botanical composition (grass, forage peanut, tropical kudzu and weeds) was evaluated before each stocking period. Swards under smaller forage allowances presented lower height, forage mass and ground cover. This condition favored the growth of forage peanut, which constituted 21.1, 15.2, 8.4 and 3.8% of forage mass in the last quarter of the experimental period, from the lowest to the highest forage allowance, respectively. Tropical kudzu was sensitive to all forage allowance levels and its percentage in the botanical composition was strongly reduced along the experimental period, especially during the dry season (July to September). Forage peanut cv. Mandobi and marandugrass form a more balanced mixture when pre-grazing sward height is maintained shorter than 45 cm. Tropical kudzu is intolerant to intensive grazing management systems when associated to marandugrass. |

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.
