Estrutura, composição florística e caracterização sucessional em remanescente de Floresta Estacional Semidecidual no Sudeste do Brasil.

This study was conducted in a fragment of semideciduous seasonal forest (SSF), located in Sorocaba (SP, Brazil), in order to verify its successional stage and infer from the future composition. Our hypothesis was that the fragment would present regeneration with low diversity of species; with predominance of pioneer species of canopy and absence of resident species in the understory and predominance of anemochoric and autochoric species. We used the parcels method, considering the individuals in three size classes, two of them referring to rhe understory and one to the canopy (1 - 100 cm and circumference at soil height 15cm. We sampled 146 species, and class 2 understory species presented the highest diversity levels. The similarity between the three classes was low. Considering the species with the highest importance values, five are pioneer and five are non pioneer. Contesting the initial hypothesis, these characteristics, plus the predominance of the zoochorich species in the three species, indicate that the fragment is in an intermediate stage of succession and has microclimatic conditions that allow the entrance and presence

Lianas, tree ferns and understory species: indicators of conservation status in the Brazilian Atlantic Rainforest remnants, southeastern Brazil

Indicators are applied faster and at lower costs than conventional surveys, providing quick and efficient responses that can facilitate protected areas management. Our aim was to select indicators from vegetation to monitor protected areas. For this purpose, we analyzed understory and quantified lianas and tree ferns in protected and non-protected areas, in order to find indicator species. Our study areas are located in Vale do Ribeira, southeastern São Paulo state, Brazil. One of the areas is under two protection categories (IUCNs categories II and V), and the other is a privately owned farm. Lianas with large diameters (> 13 cm) and tree ferns with great heights (> 19 m) were considered indicators of undisturbed areas (protected areas) because their growth is directly related to forest successional stage. Indicator species within the protected area were shade tolerant species, such as Bathysa australis (A.St.-Hil.) K.Schum., whereas outside the protected area were pioneer species, such as Pera glabrata (Schott) Poepp. ex Baill. e Nectandra oppositifolia Ness. All of the suggested indicators can be used in management actions, especially in protected areas, to guarantee forest maintenance and ensure fulfillment of the conservation objectives of these areas.
