This work analyzed the diameter distribution of one site of Atlantic Forest in natural succession, located at the Sitio Palmares Biological Reserve - state of Espirito Santo. In 2,400 m² all the trees with BDH equal or plus 5 cm were measured. The results reveal 195 trees distributed among 17 species and 15 families. The total population presented a mean BDH of 12.40 cm and a basal area of 2.86 m², corresponding to 11.90 m².ha -1 . Seven 5 cm interval diameter classes were constituted. The Normal model adjustment for the diameter distribution revealed for the total population an unimodal left-skewed tendency. The first two diameter classes, from 5 to 15 cm, accumulated 142 trees, concentrating 72.8% of the population density. Five species presented a population density of more than 10 woody individuals. The species Vismia guianensis (Aubl.) Seem. presented trees only in the first diameter class. Cecropia catarinensis Cautrec., Miconia cinnamomifolia (DC.) Naudin and Miconia multiflora Cong. presented unimodal and Piptocarpha macropoda (DC.) Baker presented inverse J diameter distribution curve. Accordingly to the successional stage of the studied fragment, after 30 years in preserved area, according the number of species and their diametric structure, the plant community is actually in the intermediate growth development, fairly distant to the climax stage. Keywords : Floristic survey; diameter classes; equations. Resumo Caracteristicas dendrometricas de um fragmento de Mata Atlântica no Municipio de Santa Maria de Jetiba, Estado do Espirito Santo, Brasil. Este trabalho analisou a distribuicao diametrica de uma area em regeneracao natural da Mata Atlântica localizado na Reserva Biologica Sitio Palmares, ES. Em 2.400 m 2 , foram medidas todas as arvores com DAP igual ou superior a 5 cm. Foram encontradas 195 arvores, distribuidas em 17 especies e 15 familias. O total da comunidade observada apresentou um DAP medio de 12,40 cm e area basal de 2,86 m 2 , correspondendo a 11,90 m 2 .ha -1 . Os individuos arboreos ficaram distribuidos em sete classes diametricas de 5 cm de intervalo. O ajuste da funcao normal mostrou, para o total da populacao, distribuicao diametrica unimodal com assimetria a esquerda. As duas primeiras classes diametricas, de 5 a 15 cm, acumularam 142 arvores, concentrando 72,8% da densidade populacional. Cinco especies apresentaram uma densidade populacional com mais de 10 individuos arboreos. A especie Vismia guianensis (Aubl.) Seem. apresentou arvores somente na primeira classe diametrica. Cecropia catarinenses Cautrec . , Miconia cinnamomifolia (DC.) Naudin e Miconia multiflora Cong. apresentaram curvas de distribuicao diametrica unimodais e Piptocarpha macropoda (DC.) Baker curva de distribuicao diametrica J-invertido. O estagio sucessional do fragmento estudado, com mais de tres decadas de crescimento em area preservada, encontra-se, pelo numero de especies e estrutura diametrica observadas, em fase intermediaria de desenvolvimento, ainda longe do estado climax. Palavras-chave : Levantamento floristico; classes diametricas; equacoes.
