COMPOSIÇÃO FLORÍSTICA ARBÓREA EM RESERVA EXTRATIVISTA NO AMAPÁ.

Current paper assessed the florist composition and vegetation diversity of a stretch of forest called Alto Cajari, within the Extrativist Reserve of the River Cajari, in the municipalities of Mazagão, Laranjal do Jari and Vitória do Jari, in the state of Amapá, Brazil. Twenty-seven 20 x 100 m plots, total area of 5.4 hectares, were investigated. Identification and counts of specimens with DAP ≥ 9 cm. Vegetal typologies in the Alto Cajari predominantly hail from the ecosystems of dense ombrophilous forest and Amazon savannah. The 27 plots comprised 437 specimens, 34 families and 74 species. Fabaceae (15 species), Anacardiaceae (5), Lauraceae and Myrtaceae (4) were highlighted in species richness. The most underscored species were Cecropia palmata Willd. (28), Byrsonima crassifolia (L.) Kunth (22), Himatanthus articulatus ( Vahl) Woodson (21), Spondias mombin L. (19), Tabebuia aurea (Silva Manso) Benth.& Hook. f ex S. Moore (18) and Trattinnickia rhoifolia Willd. (18).
