The study was developed in the fragment situated in the Catende's-PE city (Mata Santa Luzia - 8º72'49" S e 35º72'47" Wat 142 km of the capital, with 239m altitude. The present work aims to study and evaluated the total natural regeneration of arboreal species in the forest fragment and to verify the diversity and structure of the species in the same one. For estimate the natural regeneration, were made systematically 20 subunits (samples with 5 x 5 m), with 50 meters between the ones. The regeneration study (CAP < 15 cm) was developed with heights divided in three categories (1 - individuals with minimum heights 1 < 2 m; 2 - individuals with minimum heights 2 < 3 m; 3 - individuals with heights > 3 m). - individuals with heights > 3 m). In fragment was observed 25 botanical families and 36 arboreal táxons inside 107 individuals. 33 had been identified in level of species, 2 in sort level and 1 are not identify. five species obtained bigest values for total natural regeneration of the samples population (RNT) was descript following way: Rheedia gardneriana Planch. & Triana (9,9%), Cupania racemosa (Vell.) Radlk (7,7%), Brosimum discolor Schott (7,4%), Vismia guianensis (Aubl.) Pers. (6,1%), Protium heptaphyllum (Aubl.) Marchand (5,9%). These species probably they will be main responsible for the maintenance of forest's structure and physiognomy.
