Over the years, the natural landscape of Atlantic forest has undergone significant changes. Inventories carried out by the Fundação SOS Mata Atlântica and by the National Institute for Space Research (SOS Mata Atlântica and INPE, 2017), showed that 83.7% of the São Paulo territory initially covered by this biome has already been transformed into pasture, monoculture and other uses. This intensive exploration resulted in extensive degraded areas, resulting from abandonment after the loss of the productive capacity of the soil. For the recovery of physical and chemical characteristics and the reduction of soil loss due to erosive processes, forest species are planted. During planting and in the first weeks of plant growth, the lack or excess of water can limit development. In this case, an alternative used is to add water-retaining polymers to the soil that have the ability to increase water retention. This study evaluated the effect on the growth of Palmito-Juçara (Euterpe edulis Mart) seedlings of different doses of water-retaining polymer incorporated into the growing substrate, with watering on five consecutive days and with alternating watering for a period of three months in a nursery. The experiment started when the seedlings presented 220 days after sowing. The juçara plants were grown in plastic bags filled with 850 g of substrate composed of a mixture of peat, carbonized rice husk, horse manure, chicken manure, tanned bovine manure, mineral fertilizer and dolomitic limestone. To study the effect of the hydro-retaining polymer, the following doses of a polyacrylic potassium copolymer were added to the dry substrate: D0 = without adding the polymer to the substrate (control); D2 = 2g of polymer; D3 = 3 g of polymer; D4 = 4 g of polymer; and, D5 = 5 g of polymer. Each dose was combined with two irrigation regimes, watering for five consecutive days or alternating, in a 5 x 2 factorial arrangement, with 15 repetitions, totaling 150 experimental plots in a randomized block design. The transplanting of the seedlings to the bags took place in April 2019 and every 30 consecutive days, five individuals were collected from each dose and each type of irrigation (50 experimental plots / collection), that is, 3 collections (250 days, 280 days and 310 days after sowing). In each collection, the length of the leaves and the root system, the diameter of the stem, the height of the plant, the dry mass of the aerial part, the dry mass of the root and the total dry mass were measured. After checking the normality of the data and the homoscedasticity of the variances, analyses of variances were performed (ANOVA, p <0.05) and the differences between the means were compared using the Tukey test (p <0.05). The analysis of the results showed significant differences between the irrigations, with greater growth for the variables of leaf length, stem diameter, plant height and dry mass of the aerial part in the initial period of development of juçara plants. In the condition of irrigation in five consecutive days, the highlight was for dose D3 and, in alternate watering, for dose D5.

“…Em restaurações florestais, a introdução de espécies é geralmente feita por plantio de mudas. Um dos objetivos dessa etapa é atrair dispersores e estabelecer espécies lenhosas a partir da melhoria das condições de sombreamento e temperatura nessas áreas (Society for Ecological Restoration, 2004;Holl, 2013;Fonseca et al, 2017).…”

Foi realizado um estudo florístico e fitossociológico em áreas no Parque Estadual do Rio Turvo, Cajati, SP (77°89ʹ42ʺ N e 72°49ʹ22ʺ W), uma área de restauração com três anos em bananal abandonado (Rest 3) e outra área de restauração com cinco anos em pastagem degradada (Rest 5). Em cada área foram instaladas seis parcelas de 100 m2, analisando-se diâmetro e altura de todos os indivíduos com altura superior a 50 cm e fazendo-se amostragem de solos para fertilidade na profundidade 0 – 20 cm. A estrutura da comunidade foi descrita a partir dos estimadores fitossociológicos: frequência relativa, dominância relativa e valor de importância. A diversidade foi calculada pelo índice de Shannon e equabilidade pelo índice de Pielou. Na Rest 5 foram registrados 2.117 ind ha-1 (18 famílias e 39 espécies) e na Rest 3 foram 4.650 ind ha-1 (21 famílias e 54 espécies). Os parâmetros fitossociológicos refletem áreas em processos iniciais de sucessão secundária, caracterizando-se o uso anterior como bananal em um ambiente mais favorável para o desenvolvimento das espécies plantadas e estabelecimento de propágulos.

“…Thus, natural regeneration can be seen as a dynamic process, capable of providing information about the behavior, maintenance and how the incoming species are established in forest ecosystems [8,9]. In addition, natural regeneration can also be analyzed as a process of advancement or resumption of forest succession, which makes it possible to establish relationships between patterns of composition and diversity of species, with ecological processes that are associated with the dynamics of succession of communities [10,11,12].…”

Aims: Evaluate the phytosociological structure of natural regeneration, the ecological group and the species dispersion syndrome in an urban fragment of the Atlantic Forest, Pernambuco, Brazil. Study Design: Systematic sampling. Place and Duration of Study: Immaculate Catholic College Conceição do Recife (FICR), in the municipality of Recife, PE, in August 2019. Methodology: In the survey, 10 plots of 5 m x 5 m were sampled, and all living individuals with height ≥ 1 m and circumference at 1.30 m from the soil were sampled < 15 cm. The structure of natural regeneration was analyzed based on phytosociological parameters and distribution of individuals in height classes. Species diversity was estimated using the Shannon diversity and Pielou equability indices. Results: We sampled 236 individuals, belonging to 26 species. The estimated density and dominance were 9,940 ind.ha-1 and 5.27 m2.ha-1, respectively. The families with the highest species richness were Fabaceae, Myrtaceae and Bignoniaceae. The species that stood out when considering density, frequency, dominance, importance value and natural regeneration were Protium heptaphyllum, Eschweilera ovata, Casearia javitensis, Brosimum guianense, Handroanthus sp.1, Xylopia frutescens, Thyrsodium spruceanum and Myrciaria ferruginea, being considered well adapted, showing efficiency in the development and establishment of new individuals. The Elaeis guineensis it was also among those that stood out the most, and it was necessary to monitor and control, because it is an invasive alien species. The indices of Shannon diversity and Pielou equability were 2.56 nats.ind.-1 and 0.76, respectively. In the area, the initial secondary species with zoochoric dispersal syndrome predominated. The distribution of the number of individuals for height classes occurred in the following order: C3 > C1 > C2. Conclusion: The area is in the intermediate stage of ecological succession, with moderate species richness. It is necessary to monitor the area, aiming at the control of the species Elaeis guineensis and native species with low natural regeneration.
