    The intense human activity devastates large native forests areas, either for agriculture expansion or to supply the growing wood market; anyway, the small forest fragments remaining suffer constant anthropic pressure. However, the use of adapted tree species may contribute to the natural resources protection. This present study aimed the evaluation of phenological patterns from 109 forest tree species, belonging to 37 families and 82 genders, between native and exotic, with 9 years old, to differentiate the most adapted and with potential to be used in reforesting programs. The search was conducted at Incaper’s Experimental Farm, in Jucuruaba, Viana-ES city, (UTM E-345524, N-7741039). It was performed soil chemical analysis of the planted area and the weather data was obtained in Viana’s meteorological station. The study was based on the observation of the number of surviving plants from each specie and its growth evaluation. Observations of the budding phenophases, leaves senescence, flowering and fruiting were performed. Phenological evaluations were developed monthly, from November 2012 to October 2013. It were collected data from the measurement of tree height, diameter at breast height (DBH), index of foliage, survival rate and calculating the CGI (Combined Growth Index), as well as the determination of the most appropriate species. From the 109 species studied, 64.22% showed functional and structural adaptation to soil and climate conditions of the experimental region; 42.22% flowered and fruited; and 90% showed senescence and budding following seasonality. Twenty-nine species showed a GIC higher than the average. Most species stood out as an alternative to local vegetation recovery, especially Inga uruguensis and Schizolobium amazonicum. The chlorophyll fluorescence analysis revealed that the photosynthetic apparatus of Schizolobium amazonicum was able to protect it from photoinhibition and promote good conversion of light energy into photochemical.

    Estoques totais de carbono ecossistêmico e sua potencial vulnerabilidade à elevação do nível do mar em manguezais da Baía de Vitória

    Mangroves are important carbon sinks, capable of sequestering and storing organic matter through its accumulation in both vegetation and soils. In Vitória Bay, these ecosystems face increasing pressures from mean sea level rise and urban expansion, which limits the landward migration of mangroves. This study was based on the hypothesis that mangroves located at lower elevations, due to their greater exposure to potential erosive processes and frequent inundation, would exhibit lower carbon stocks, as such processes could have removed part of the previously accumulated carbon and compromised their retention capacity. This study aimed to quantify total ecosystem carbon stocks in mangrove forests and to compare these stocks with coastal vulnerability indices in the metropolitan region of Vitória, southeastern Brazil. Total carbon stocks were quantified for six mangrove sites, including aboveground vegetation and soils down to 3 m depth. A guided classification of Vitória Bay was conducted to assess vulnerability based on spatial interpolation maps and the Coastal Sensitivity Index (CSI) developed by Machado and Albino (2024), which considers parameters such as overall vulnerability, elevation, geology/geomorphology, sedimentary features, and proximity to the coastline and river mouths.To compare with the CSI, in situ data on flood frequency and duration, water column depth, and elevation of the mangrove fringe (using RTK GPS) were collected at the six sampled sites. Our results showed that total carbon stocks in the six mangrove forests ranged from 717 to 1481 Mg C ha⁻¹, with an average of 1028 Mg C ha⁻¹, with over 90% of the carbon stored in the soils. The CSI indicated the sampled areas had high overall vulnerability, with site A classified as very high vulnerability, particularly due to its geology/geomorphology and sedimentary characteristics. In situ data classified site A as highly vulnerable, as it showed the lowest average elevation (-1.28 m), indicating greater exposure to flooding. Contrary to the initial hypothesis that mangroves in lower areas would have lower carbon storage capacity due to potential erosion, the lower areas of the Bay of Vitória showed the highest carbon stocks. This suggests that, even under greater physical vulnerability to these pressures, these mangroves continue to play a significant role in carbon retention, possibly due to soil accretion driven by aboveground plant material associated with root systems. This study indicates that, in the protected estuarine mangroves of Vitória Bay, carbon stocks are not primarily associated with vulnerability to coastal erosion related to wave action, highlighting the importance of integrating local hydrodynamic characteristics and terrain topography into conservation strategies and adaptive management in the context of climate change
