Item Análise da regeneração natural em áreas de restauração florestal na Zona da Mata Sul de Pernambuco(2023-09-14) Calixto, Shermesson Henrique Mota; Feliciano, Ana Lícia Patriota; Silva, Marília Isabelle Oliveira da; http://lattes.cnpq.br/1029149032423660; http://lattes.cnpq.br/9184673853412326; http://lattes.cnpq.br/3349917891877024In the evaluation of the restoration process, natural regeneration is a relevant indicator for evaluate the functioning of recovering ecosystems. This is because it represents the processes of species establishment and the sustainability of the tree community, which is responsible for triggering ecological processes. This study aimed to analyze natural regeneration in two riparian areas located in the South Wood Zone of Pernambuco, with the intention of inferring about the forest restoration process of these environments. The work was carried out in two areas undergoing restoration (Palma III and Palma IV), located in Sirinhaém/PE. Twenty plots (5 x 5 m) were installed in each study area, and floristic and phytosociological surveys were conducted to verify composition and structure. Regenerating individuals were considered those with a height equal to or greater than 1 m and with a circumference at breast height (CBH) less than 15 cm. After species identification, their origin, endemism, ecological groups, dispersal syndromes, and pollination syndromes were determined. The main results of the floristic analysis showed that the majority of species in the Palma III area (PIII) are early successional species, while pioneers occupy that space in the Palma IV area (PIV). In both areas, most species have zoochorous dispersal syndrome and melittophilous pollination syndrome, and they are native to the Atlantic Forest biome and not endemic. In the PIII area, the species Guarea guidonia was dominant, representing 70.80% of the total density of the study and occupying 85% of the plots with a total of 80 individuals. These factors resulted in low diversity and evenness indices in the area. Guarea guidonia was also the dominant species in the PIV area, but with a more balanced proportion of individuals, with 21 individuals representing a total density of 31.34%, present in 50% of the plots.

This objective work generates a qualitative and quantitative diagnosis of nurseries in the state of Pernambuco, aiming to obtain the current production capacity and diversity of seedlings of forest species. For this reason, 110 nurseries were listed for the application of a structured questionnaire, of which only 44 responded to the questionnaire by telephone call or electronic form. The questionnaire was divided into 6 blocks of questions, namely: BLOCK I – Consent to the interview; BLOCK II – Identification of the nursery and owner; BLOCK III – Production of seedlings; BLOCK IV – Socioeconomic Characterization; BLOCK V – Regulation and BLOCK VI – Contact with other nurseries. In addition, the interviewees sent a list of species that are produced in their nurseries to determine the diversity produced. All data were tabulated and analyzed using Google spreadsheet and Microsoft Excel 2010. To prepare the distribution map of the nurseries participating in the research, QGIS 3.10.11 was used. The forest nurseries in Pernambuco are distributed throughout the state, with the majority in the Sertão and Agreste, where they produce 180 native species and 141 exotic species, with an average diversity of 17 native species. For large nurseries, there was no direct influence between productive capacity and diversity of native species. Seed collection is mainly done in natural forests and seed quality is a challenge for nurserymen. Furthermore, there is a large gender gap in the sector, with most nurseries being male-owned and few female employees working in them. Most nurseries have between 1 and 5 workers, and the presence of Agricultural Engineers is more common than that of Forestry Engineers in nurseries registered with Renasem. And finally, although most nurseries are not registered with Renasem, this does not necessarily imply irregularity due to the existing exceptions.
