Abstract: the serra de itabaiana national park is distinguished by its phytophysiognomic diversity, among which, a locally known as areias brancas (white sands), an open vegetation, ranging from herb-shrub to shrub-tree and classified by some authors as restinga or cerrado, depending on its size. aiming to characterize and classify vegetational type were selected two sites in areias brancas of serra de itabaiana national park and built a list following deposited material in the ase herbarium and additional sampling. to the phytosociological study it was used the wandering quarter method, sampling all individuals with trunk circumference (> 15 cm) at breast height (1.30 m). it was verified, at the areias brancas, the occurrence of 193 species belonging to 145 genera and 60 families that are mostly represented by herb and shrub species. it is noticeable the high number of species found in areias brancas when compared with studies conducted throughout the national park. there are significant floristic similarity between sampling sites, but structurally the two areas should be considered as different sucessional faces, due to variations in density, height and dominance. even with plant species in common, the areias brancas of the national park can not be classified as restinga or cerrado for not having common origins for these formations. the areias brancas should be considered as an ecological refuge, an azonal vegetation derived from the special conditions of substrate formation.

Abstract: Estudos de estrutura de tamanho e de estágios ontogênicos s o importantes para se compreender quais fatores influenciam os processos populacionais, a regenera o e a resposta a perturba es de uma popula o. Este estudo analisou a estrutura de uma popula o de Kielmeyera rugosa Choisy (Clusiaceae) no hábitat de Areias Brancas do Parque Nacional Serra de Itabaiana, Estado de Sergipe. Amostraram-se aleatoriamente 30 parcelas de 20 x 25 m, nas quais se determinou a abundancia de indivíduos jovens e adultos, a circunferência do tronco, a altura da copa e o número de caules por planta. A distribui o espacial de jovens e adultos na popula o é agregada, causada por sua predisposi o em formar grupos em locais onde há maiordisponibilidade de recursos e condi es favoráveis. Outro fator que contribui com a agrega o é a dispers o anemocórica da espécie. A popula o estudada apresentou o maior número de indivíduos nas categorias menores de altura e de DAS, indicando que a popula o está em crescimento ou em processo de autorregenera o. Há maior número de indivíduos de 2-3 m de altura, o que se deve ao fogo ou corte, eventos que n o foram capazes de interromper o processo de recrutamento ou reprodu o da espécie na área, pois n o ocorreram lacunas nas classes de diametro de caule. Studies on structure, size and ontogenic stages are important to understand which factors influence population processes, regeneration and response to disturbances of a population. This study examined thestructure of a population of Kielmeyera rugosa Choisy (Clusiaceae) in white sands habitat of Serra de Itabaiana, Sergipe State. Thirty 20 x 25 m plots were selected randomly selected, and their abundance of young and adult plants was recorded, as well as trunk circumference, crown height and number of stems per plant. The spatial distribution of young and adult population is aggregated, caused by their predisposition to form groups in localities with large availability of resources and favorable conditions. Another factor contributing to the aggregation is the anemochoric dispersion of the species. The study population had the highest number of individuals in lower classes of height, with few individuals in larger classes, indicating that the population is growing or in a process of selfregeneration.There are more individuals 2-3 meters high, due to burning or cutting. These events were not able to stop the recruitment process or reproduction of the species in the area, as observed by the lack of gaps in the classes of stem diameter.

Abstract: This study aimed to map and characterize the vegetation of the National Park of Serra de Itabaiana, with emphasis on the most abundant plant species, evaluating strategies for their conservation. There was a predominance of open formations of grassy fi elds, characterized as high-altitude grassland (3,289ha), mainly in areas of slopes. The forests are characterized as ecotones between Lowland Dense Rain Forest and Semideciduous Forest (2,643ha), mostly as secondary forest. The habitat called the White Sands (347ha), previously characterized as salt marshes, only occurs on the eastern side of Itabaiana and Comprida Serras, and it has a type of physiognomy normally associated with high-altitude grassland. The disturbed areas are concentrated at the edges of the park, roads and trails used by human visitors. Of these areas, regions with exposed soils are the most abundant, occurring in a total of 699ha; the brushwood (586ha) is more frequent at the forest’s edge, originating from fi res caused by the cultivation of sugar cane; plantations and withdrawals of soil (131ha) occur in areas close to settlements.agreste; description; protected areas; white sand
