Diagnóstico dos viveiros florestais do estado de Pernambuco.

Abstract

Faced with so many commitments and ambitious environmental goals signed, the Forest Restoration sector will require a large amount of seedlings and seeds of native tree species, requiring a great deal of prior planning. 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.
