Previous issue date: 2014-11-17 / This paper aims to study the floristic of areas of Brazilian Savannas in state of Bahia and compares them to the physiognomies present in Coastal Plain in east of Bahia which are considered disjoint cerrado. The methodology of this work consisted of establish five sampling areas in the state of Bahia: 1) Savanna physiognomy in the west of Bahia; 2) In the Chapada Diamantina; 3) In the Coastal Plain; 4) Restinga in the northern littoral of Bahia; 5) Restinga in the southern littoral of Bahia. The sampling areas were performed using the point centered quarter method, being in each area were sampled 100 points 20m far between distributed in 10 transects with 10 points each, considering the degree of conservation in each study area. All woody individuals with DBH ? 3 cm closer to each point were sampled in that survey totaling 400 individuals per area. A sum of 2.000 individuals were sampled. The Shannon index (H') was used to estimate the diversity of each area. The Jaccard index of similarity (cluster method) was used to determine the floristic similarity between transects and study areas. Were sampled 78 species in the Western Savanna formations distributed in 31 families; estimated the diversity by the Shannon index H' = 3,61 to 3,93; 68 species in the Chapada Diamantina Savanna formations distributed in 30 families and estimated the diversity by the Shannon index between 3,49 to 3,45; 83 species in Coastal Plains distributed in 38 families wich estimated the diversity by H? = 3,46 to 3,89; 73 and 69 species in the restingas in the Northern and Southern littoral distributed in 36 and 33 families; estimated the diversity by the Shannon index H'=3,61 to 3,97 and H? = 3,68 to 3,85. Cluster analysis indicated that the floristic similarity found between coastal plain in the east of the State of Bahia and restinga formations (coast) indicating floristic relationship between the areas. The Savanna formations in the west of Bahia and Chapada Diamantina presented 30% of similarity. There by the analysis of this work showed more evident relationship of the floristic in Coastal Plains to the Atlantic forest physiognomy therefore these areas should be treated as Atlantic forest physiognomy related including all legal aspects of conservation and forest management provided by law n? 11.428/2006 and resolutions of CONAMA. / Este trabalho teve por objetivo determinar e comparar flor?sticamente as ?reas de Savanas encontradas na Bahia e compar?-las ?s fisionomias encontradas sobre os Tabuleiros Costeiros no Leste da Bahia, consideradas ?reas de Cerrado disjuntos. Para condu??o do trabalho foram estabelecidas cinco ?reas de amostragens na Bahia, sendo: 1) fisionomias Sav?nicas localizados na regi?o Oeste; 2) na Chapada Diamantina; 3) nos Tabuleiros Costeiros; 4) Restingas noLitoral Norte; 5) Restingas do LitoralSul. A amostragem nas ?reas foram realizadas atrav?s do m?todo de pontos-quadrantes, sendo alocados em cada ?rea amostral 100 pontos equidistantes em 20 m, distribu?dos em 10 transec??es, com 10 pontos cada, respeitando-se o grau de conserva??o de cada ?rea estudada. Em cada quadrante, foram amostrados os indiv?duos lenhosos com DAS ?3 cm, mais pr?ximos de cada ponto, perfazendo um total de 400 indiv?duos por ?rea, perfazendo um total de 2.000 indiv?duos amostrados. A diversidade de cada ?rea analisada foi estimada pelos ?ndices de Shannon-Wiener(H?). Para determina??o da similaridade flor?stica entre as ?reas estudadas foram realizadas an?lises de agrupamentos a partir do ?ndice de similaridade de Jaccard (J). Nas fisionomias sav?nicas da regi?o Oeste do Estado foram amostradas78 esp?cies, distribu?das em 31 fam?lias; a diversidade estimada pelo ?ndice de H? = 3,61 a 3,93; nas fisionomias sav?nicasda Chapada Diamantina 68 esp?cies, distribu?das em 30fam?lias, a diversidade estimada pelo ?ndice de Shannon-Wiener (H?) variou de 3,49 a 3,45; para os Tabuleiros Costeiros 83 esp?cies, distribu?das em 38 fam?lias, a diversidade estimada pelo ?ndice H? = 3,46 a 3,89; para as Restingas do Litoral Norte e Sul, obteve-se respectivamente, 73 e 69 esp?cies distribu?das em 36 e 33 fam?lias, a diversidade estimada pelo ?ndice de Shannon-Wienervariou deH? = 3,61 a 3,97 e H? = 3,68 a 3,85,respectivamente. As an?lises de agrupamento apontaram similaridades flor?sticas entre os Tabulerios Costeiros no Leste do Estado com as fisionomias de restingas (no Litoral), indicando rela??o flor?stica entre as ?reas.J?as fisionomias sav?nicas do Oeste e da Chapada Diamantinaapresentaram 30% de similaridade. Assim, pelas an?lises deste estudo evidenciou-se uma maior rela??o flor?stica dos Tabuleiros com as fisionomias de Mata Atl?ntica, portanto, estas ?reas devem ser tratadas como fisionomias relacionadas a Mata Atl?ntica, inclusive quanto aos aspectos legais de conserva??o e manejo, previstos na Lei n? 11.428/2006 e Resolu??es do CONAMA.
