Although the Brazilian Cerrado occupies a large continuous area in central Brazil, it also occurs in disjunct patches across other regions. In the semi-arid zone, some of these patches have shown greater floristic and ecological affinity with the Caatinga and are thus referred to as caatinga savannas. These areas exhibit diverse vegetation types, with varying densities depending on the degree of arboreal cover. identified the flora and characterized the natural vegetation of four sites located in two municipalities in the state of Ceará: Granja (Fazenda Quilómetro 35, Papagaios, and Vereda dos Tomás) and Martinópole (Bom Princípio), within the Coreaú River Basin. The classical sigmatist method of Braun-Blanquet was applied for vegetation survey, followed by a classificatory analysis (Modified Twinspan) to distinguish plant communities. Botanical expeditions and phytosociological inventories were conducted unsystematically in 2018, 2023, and 2024. A total of 73 phytosociological inventories were carried out, allowing the identification and proposal of 10 plant communities, classified as arboreal, arboreal-shrub, shrub, and herbaceous. The synphytosociological analysis led to the proposal of two edaphophilous vegetation series.
