“…Considerando a fisionomia arbórea de áreas antropizadas em relação a esperada em ambientes cobertos por florestas, torna-se importante entender os mecanismos de transformações da composição florística e da estrutura ocorrentes na sucessão secundária, uma vez que a regeneração natural impulsiona a restauração das florestas após distúrbios naturais ou antrópicos (Marchesini et al 2009, Silva et al 2010. Acrescenta-se que diferenciar a estrutura do componente arbóreo e da regeneração natural pode evidenciar quais comunidades florestais se apresentam em estádios sucessionais distintos e fornecer indícios sobre a dinâmica de populações e de comunidades.…”

RESUMO -Compreender a fi tossociologia e fatores ecológicos condicionantes pode subsidiar intervenções em fl orestas. Nesse contexto, objetivouse analisar os componentes arbóreo e regenerante e a infl uência das variáveis ambientais na distribuição de espécies, em uma Floresta Estacional na região central do Rio Grande do Sul. O estrato arbóreo foi amostrado em 33 parcelas instaladas sistematicamente, sendo em cada parcela instaladas subunidades para amostrar a regeneração natural. As principais espécies no componente arbóreo foram Trichilia clausseni C.DC. e Nectandra megapotamica (Spreng.) Mez e na regeneração natural foram Trichilia elegans A. Juss. e Cupania vernalis Cambess. Relevo, solo e dossel condicionaram espécies do estrato arbóreo e regeneração natural. O estádio regenerante das espécies foi condicionado por variáveis distintas das relacionadas ao estádio adulto. Contudo, ocorreram casos em que apenas uma variável, por exemplo, a relação entre o teor de matéria orgânica no solo e Trichilia elegans, infl uenciou tanto o estádio adulto quanto o regenerante. Palavras-chave: conservação fl orestal, ecologia, relação ambiente-vegetação ABSTRACT -Phytosociology and ecological factors on vegetation in a seasonal forest in the central area of Rio Grande do Sul, Brazil.Understanding the phytosociology and conditioning ecological factors of the vegetation can subsidize interventions in forests.. We analyzed the arboreal stratum and natural regeneration, as well as the infl uence of environmental variables on species distribution in a seasonal forest in central Rio Grande do Sul, Brazil. Thirty-three plots were systematically installed for the arboreal stratum sampling. In each plot, the natural regeneration Class I and Class II were measured. The main species were Trichilia elegans and Cupania vernalis in natural regeneration and Trichilia clausseni and Nectandra megapotamica in arboreal stratum. Relief, soil, and canopy infl uenced the arboreal stratum and natural regeneration of species. In general, the regenerating stage of the species was conditioned by distinct variables from those related to the adult stage. However, there were cases where only one variable infl uenced both the adult and the regenerating stages, such as the relationship between soil organic matter content and Trichilia elegans.

“…Natural regeneration allows the effective analysis to diagnose the conservation state of the fragment and the response to the management as it represents the set of individuals that can be recruited for the later successional stages (SILVA et al, 2010).…”

“…According to Silva et al (2010), the knowledge of the forest structure, combined with the analysis of natural regeneration, has a great importance for the elaboration of restoration plans, conservation and management of forest fragments, ensuring the maintenance of the community and composition species characteristics. However, when applied to a temporal scale, it contributes to a better understanding about the level of ecological stability and forest restoration velocity (SILVA et al, 2010).…”

-The objective of this study was to evaluate the structure (horizontal and vertical) of a Deciduous Forest, located between the municipalities of Piratuba and Ipira (SC). 14.000 m 2 of tree communities were analyzed, sub-divided into 14 plots of 10 x 100 m, where all individuals with DBH equal to or greater than 4.0 cm were sampled and identified. For natural regeneration were sampled 560 m 2 , divided into 14 plots of 10 x 4 m. In the tree strata were sampled 2.125 individuals belonging to 34 families, 80 genera and 113 species with a total density of 1.517 ind.ha -1 . Natural regeneration were sampled 196 individuals belonging to 24 families and 49 species with a total density of 3.500 ind . ha -1 . Luehea divaricata Mart., Actinostemon concolor (Spreng) Müll. Arg. and Parapiptadenia rigida (Benth.) Brenan had of value of increased importance (7,1%, 7,0 % and 5,3%, respectively) . Actinostemon concolor got high value Relative Natural Regeneration (18,1%). The low percentage of natural regeneration of species as Luehea divaricata and Parapiptadenia rigida, respectively 3,7% and 1,5%, typical of EDF , may represent a maintenance commitment in the community. The study revealed the presence of exotic species with invasive potential, as Hovenia dulcis Thumb. These facts point to the importance of the adoption of management measures, since the forest fragment studied is advancing successional terms, however, anthropogenic interference with signals in the floristic composition. These facts point to the importance of the adoption of management measures, since the forest fragment studied is suffering anthropogenic impact, influencing the ecological succession mechanisms.

“…From an environmental perspective, the growth of forests contributes for the absorption of carbon from the atmosphere, the reestablishment of hydrological functions of primary forests and the recovery of biodiversity. Studies on floristic composition are needed for that the mechanisms of transformation of the forest and its structure can be understood (SILVA et al, 2010). Such knowledge constitutes a basic tool for taking measures which aim the acceleration and guidance of the process of secondary succession, whether for preservation or commercial production.…”

The increasing importance of secondary forests all over the world alerts us to the urgent need to understand the biophysical and social underlying factors that affect its regeneration after the abandonment of agricultural practices and natural disturbances. In the state of Amapá, studies related to the structure of secondary forests are still scarce. Therefore, this article aims to characterize the floristic composition and structure in two stretches of secondary forest in the eastern Amazon, state of Amapá. For the floristic and phytosociological study of tree species, 10 plots of 10 x 100 m (1.0 ha) were established: five plots in the community of São Francisco do Iratapuru and five plots in the community of Santo Antônio waterfall, totaling half a hectare (0,5 ha) in each area. In all plots, subjects with diameter at breast height (DBH) ≥ 5 cm were considered. In total, 1,183 subjects were sampled in the two stretches of forest. In stretch 01, 565 subjects belonging to 74 species, 55 genera and 33 families were recorded. In stretch 02, 618 subjects belonging to 26 species, 23 genera and 15 families were recorded. The Shannon diversity index (H'), estimated for stretch 1, was 3.52; and for stretch 2 (2.23). The two studied stretches, despite being registered at the same age, showed significant difference in the species richness, which is the major factor for diversity differences, resulting in low similarity between the studied forests.
