The Northeast of Brazil is the largest part of its territory occupied by scrub which is characterized by being a xerophytic vegetation considered by experts the biome most sensitive to human interference and global climate change. This study aimed to characterize the floristic composition and structure in a remnant of savanna located in Reserva de Particular de Patrimonio Natural (RPPN) in the Farm Trussú in Iguatu Ceará. 45 plots were established and sampled 10x20 cm all living and dead individuals with a stem diameter at the ground level > 3 cm and total height of > 1 m. The estimated density was 5,602 individuals ha-1 representing 52 species, 41 genera and 23 families. The studied area featuring a variety of woody component similar to that found in other areas of savanna, with Shannon diversity index of 2.19 nats/ind and equitability 0.50. The species Croton sonderianus, Combretum leprosum, Mimosa caesalpiniifolia and Mimosa tenuiflora had greater importance value index. The study area is well preserved and recovery process.
