“…Essa assertiva está de acordo com Cerri et al (2018) para os cerrados de Rondônia e Stier et al (2020) quando asseguram que o conhecimento sobre a flora local e suas relações ecológicas pode aumentar a conscientização dos formuladores de políticas e da sociedade em geral sobre a fragilidade das savanas e a raridade de espécies e o alto valor ecológico e cultural ameaçados por práticas agrícolas, espécies invasoras e loteamentos. Para tal, deve-se mensurar os impactos de diferentes políticas na natureza, cenários representando os resultados desejados para biodiversidade e serviços ecossistêmicos que poderão ser usados para informar como políticas podem garantir a integridade das savanas (Resende et al, 2020).…”

As savanas amazônicas formam ecossistemas ambientalmente degradados e subestimados, sobretudo no que se refere à dinâmica da vegetação e aos processos ecológicos ocorrentes. Com o objetivo de determinar a composição florística e a estrutura de comunidades vegetais em fragmentos de Cerrado disjunto, este trabalho foi desenvolvido em cinco áreas oreádicas costeiras, localizadas no Nordeste Paraense e Ilha do Marajó, PA. Os dados foram coletados seguindo o protocolo de Avaliação Fitossociológica Mínima em paisagens com maior nível de conservação, incluindo exemplares lenhosos vivos, com diâmetro do caule ao nível do solo (DCNS3cm) ≥ 3 cm e adotando-se a distribuição em classes de altura estratificadas em CI (≤ 4,19 m), CII (4,2-7,56 m) e CIII (≥ 7,57 m) e; em classes de diâmetro em CI (3-7 cm), CII (7,1-12 cm), CIII (12,1-17 cm), CIV (17,1-22 cm) e CV (≥ 22,1 cm). Em cinco ha de savanas foram registrados 3.984 indivíduos, distribuídos em 33 famílias, 54 gêneros e 69 espécies. Fabaceae (8), Myrtaceae (6) e Malpighiaceae (5) destacaram-se com maior riqueza e Malpighiaceae em abundância. Byrsonima crassifolia (1.413), Curatella americana (660) e Myrcia cuprea (544) obtiverm maior número de indivíduos e valor de importância em todas as áreas, acompanhadas por Himatanthus articulatus e Hancornia speciosa. A classe CI de altura e de diâmetro agrupou o maior número de indivíduos e a maior diversidade e grau de similaridade florística entre as classes CI e CII. A hiperdominância de indivíduos das espécies de maior participação na estrutura vertical, típicas das savanas amazônicas, indica uma adequação a ambientes com condições distróficas, em solos arenosos ácidos e com baixo conteúdo de nutrientes e; assegura afirmar que estas áreas de savanas são jovens, ainda em fase de desenvolvimento. Floristic and structure of the woody species in five savannas in the state of Pará, BrazilA B S T R A C T Amazonian savannas form environmentally degraded and underestimated ecosystems, especially with regard to the dynamics of vegetation and the ecological processes that occur. With the objective of determining the floristic composition and the structure of plant communities in fragments of disjointed Cerrado, this work was developed in five coastal oreadic areas, located in the Northeast of Pará and Ilha do Marajó, PA. Data collections were performed following the Minimum Phytosociological Assessment protocol in landscapes with a higher level of conservation, including live woody specimens, with stem diameter at ground level (DCNS3cm) ≥ 3 cm and adopting stratified height classes: CI (≤ 4.19 m), CII (4.2-7.56 m) and CIII (≥ 7.57 m) and diameter classes in CI (3-7 cm), CII (7.1-12 cm), CIII (12.1-17 cm), CIV (17.1-22 cm) and CV (≥ 22.1 cm). In five ha of savannas 3,984 individuals were registered, distributed in 33 families, 54 genera and 69 species. Fabaceae (8), Myrtaceae (6) and Malpighiaceae (5) stood out with greater wealth and Malpighiaceae in abundance. Byrsonima crassifolia (1413), Curatella americana (660) and Myrcia cuprea (544) stood out in number of individuals and importance value in all areas, accompanied by Himatanthus articulatus and Hancornia speciosa. The data showed that the CI class of height and diameter grouped the largest number of individuals and the largest number of individuals, diversity and degree of floristic similarity between classes CI and CII. The hyper-dominance of individuals of the species with greater participation in the vertical structure, typical of the Amazonian savannas, indicates an adaptation to environments with dystrophic conditions, in acidic sandy soils and with low nutrient content and; ensures that these savanna areas are young, still under development.Keywords: Phytosociology; structural classes; typical species.

Modeling desirable futures at local scale by combining the nature futures framework and multi-objective optimization

Envisioning positive scenarios that recognize the multiple values of nature is fundamental for designing transformative changes in local socio-ecological systems. This study developed a protocol with three specifications for operationalizing the Nature Futures Framework (NFF) in a landscape scenario analysis using a multi-objective optimization framework composed of: (1) exploring nature-positive futures, (2) seeking alternative pathways for targets satisfying visions of plural values, and (3) screening key direct drivers to achieve the targets. This research conducted a case study of a rural landscape in northeastern Japan. First, 110 strategies of landscape management options were simulated from 2015 to 2100 using a forest landscape model, LANDIS-II. The simulation developed a data frame of four integrated indicators of the NFF values for each year and strategy. Second, nature-positive strategies were screened using the common values. Pareto optimal strategies were then identified to obtain equally good solutions. Finally, the key response options to achieve good nature-positive futures were identified using decision tree analysis. Our protocol identified (1) multiple, but few nature-positive and Pareto optimal strategies that satisfied NFF visions, (2) nature-positive, but not Pareto optimal strategies, and (3) non-nature-positive strategies. In most Pareto optimal strategies, the maximized value perspectives changed over time. Our protocol also identified key response options to achieve three different NFF value perspectives in the case study area: (1) clear or selective cutting in forestry and (2) solar PV installation on abandoned pastureland in agriculture and energy sectors. We discussed the implication for local landscape management, localizing NFF narratives to develop future scenarios and modeling practice of NFF. The protocol does not depend on a specific model and indicator. Thus, our scalable protocol can be applied to scenarios and model practices in any region to support envisioning plausible, feasible, and positive futures, and designing future stakeholder collaboration.
