Item Diagnóstico dos viveiros de mudas florestais no município de Gravatá - PE(2024-10-03) Lima, Pollyana Gomes da Silva; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/3458909580899001Considering that the current supply of native tree seedlings is not compatible with market growth projections for the coming years, the need to increase production to meet potential oration sector, environmental regularization, and possible supply to one of Pernambuco's furniture hubs. In this sense, this work aims to diagnose forest seedling nurseries in the county of Gravatá and to propose the development of a project to implement a new forest nursery in the rural area of the county. Therefore, 11 nurseries that produce and/or resell forest seedlings in the region were found to be analysed and interviewed, of which 5 agreed to respond to a questionnaire that aims to analyse their operating profiles and identify productive aspects; generating an information base for a SWOT analysis that results in an action plan, which brings an arrangement of suggestions coherent with the local reality supporting the aim of the study and substantiate the design, which was modeled using SketchUp 2019 software. The study showed that the forest nurseries present in Gravatá have a timid performance regarding seedling production, with 80% of them only resellers, making it clear that seedling production is not yet seen as a significant business in the municipality. Regarding infrastructure, the forest seedling nurseries in the municipality have basic infrastructure components. Regarding species diversity and productive capacity, there are seedlings produced and/or resold are mostly exotic species, coming from nurseries with an annual capacity of up to 10 thousand seedlings, whose main destination is local landscaping. The main problems faced were technical difficulties in cultivation and low availability of seeds. Aiming to give greater robustness to the municipality's forest nursery framework, as well the supply of potential demand for forest seedlings in the coming years are met, the project to implement a new nursery was taken as a starting point, with an annual production capacity equivalent to a total of 3,488 to 8,208 seedlings produced in bags and tubes, based on the considerations brought by the action plan generated from the analysis carried out.Item Crescimento e qualidade de mudas de Piptadenia stipulacea (Benth.) Ducke, em diferentes recipientes e doses de fertilizante misto(2024-09-12) Souza, Thallyta Valentin dos Santos de; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/1375547405957419In 2022, Brazil suffered a neduction of 2.05 million hectares of native forest, the Caatinga biome, in tum, lost the equivalent of 140.637 hectares. This highlights the urgency of actions to curb environmental degradation and promote conservation. It is vital to invest in research on native forest species to fill technological gaps, meet the demand for seedlings and drive sustainable development. Piptadenia stipulacea (Benth.) Ducke, a species native to Brazil, is a recommended option for recoverins degraded areas in the Caatinga. Therefore, the objective o£ this work is to evaluate the influence of the volumetric capacity of containers for the production of seedlings such as tubes and polyethylene bags, combined with different doses of NPK, on the growth and quality of seedlings of Piptadenia stipulacea (Benth.) Ducke. The study was carried out in the forest nursery of the Forestry Science Department of the Federal Rural University of Pernambuco (UFRPE), from November 2022 to March 2023. Three containers were tested for the production of seedlings: a 120 cm3 tube, a 280 cm3 and plastic bag of 3449 cm3 (20 cm x 30 cm) and four doses of NPK (4-14-8): 0; 2.0; 4.0; 6.0 Kg/m3. The analyzes of height and diameter of the stem were monitored monthly and a destructive analysis was performed at the end of the 120 days. The results indicated that the reduction in container volume caused a decrease in dry mass, diameter and height. Increasing NPK doses had a significant effect on recipient height and stem diameter. For the robustness index, the dose of 2 kg/m3 obtained the best performance. In view of the results, the use of polyethylene bags with the addition of 2 kg/m3 of NPK is recommended for the production of jurema branca seedlings.Item Planejamento da arborização urbana: estudo de caso da Avenida Duque de Caxias, São Lourenço da Mata - PE(2024-10-01) Cravo, Amanda Clarinda de Melo; Lima Neto, Everaldo Marques de; http://lattes.cnpq.br/6791561445213969This study focused on urban tree planning along Duque de Caxias Avenue, considering its feasibility and associated costs. The objective was to evaluate the physical conditions of the road and specific challenges, following the guidelines of the Urban Tree Planting Manual of Recife. Small-sized species suitable for sidewalk widths and wire heights were selected, essential to mitigate risks and reduce seedling mortality rates. The methodology included a detailed survey of available planting spaces, identifying 179 viable intervals, albeit limited by the scattered presence of urban elements such as poles and signage boards. The results highlighted the need for 2130 seedlings to cover the planned demand, considering a mortality rate of 50%. Cost assessments from nine local nurseries revealed budgets ranging from R$ 383,400.00 to R$ 440,200.00, emphasizing the complexity and economic challenges associated with acquiring seedlings in a region with scarce available native species. Additionally, a significant gap was identified in the supply of native species seedlings in local nurseries, underscoring the importance of effective policies for urban biodiversity conservation and encouragement of local seedling production. It is concluded that integrated and participatory planning is crucial for the success of urban tree planting initiatives, actively involving local communities, government agencies, and research institutions. This approach not only contributes to improving urban quality of life but also strengthens city resilience in the face of environmental challenges. This study not only provides relevant information for the practical implementation of urban tree planting projects but also highlights the ongoing need for adaptation and innovation in urban policies to promote greener and more sustainable urban environments aligned with sustainable development goals.Item Diagnóstico de redes de sementes florestais no Brasil(2024-02-07) Silva, Ana Clara Santana; Santos, Marcone Moreira; http://lattes.cnpq.br/3284707164193715; http://lattes.cnpq.br/5674898094215400Forest seed networks play a fundamental role in the preservation and restoration of forest ecosystems, representing initiatives aimed at conserving native plant species in different biomes. These networks work collaboratively, with the active participation of various social actors, such as local communities, non-governmental organizations (NGOs), research institutions and government entities. The objective of this study was to carry out a comprehensive mapping of forest seed networks in Brazil, with the aim of understanding their distribution, structure and impact on the conservation and restoration of forest ecosystems. For this survey, four methods were adopted: research on the networks' web pages, analysis of Instagram profiles and application of questionnaires, consultation of RENASEM/MAPA with specific filters and analysis of academic articles on Scholar Google, using specific keywords. As a result, it was possible to map twelve forest seed networks in Brazil, identifying four main actors involved. A significant concentration of these networks was evident in the Center-West and Southeast regions of the country, with a significant diversity of native species from the Cerrado, Atlantic Forest and Amazon biomes. The main research institutions and non-governmental organizations were highlighted as the main actors involved in this context.Item Diagnóstico dos viveiros florestais do estado de Pernambuco(2023-04-26) Silva, Mylena Raiza dos Santos; Freitas, Eliane Cristina Sampaio de; http://lattes.cnpq.br/7525975084334972; http://lattes.cnpq.br/4717057526135120Faced 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.
