“…Some species, such as A. marina, tend to make significant investments in root biomass, which may reflect the difficulties of growing in nutrient-depleted, hypoxic, and unstable soils. The current study found a below ground biomass accumulation rate of 1.3 (range: 1.2-1.4 t ha -1 yr -1 ) for R. mucronata zone, which was significantly greater than the 0.2 t ha -1 yr -1 for Rhizophora apiculata in the Hinchinbrook channel, Australia (Clough, 1998). Similarly, the contribution of below-ground biomass to total biomass accumulation was 14 percent, which was slightly greater than the 8.5 percent recorded for the Rhizophora species in Malaysia (Ong et al 1995).…”

Abstract. Githaiga MN, Kotut K, Kariuki F, Kairo JG. 2019. Structure and biomass accumulation of natural mangrove forest at Gazi Bay, Kenya. Bonorowo Wetlands 9: 18-32. The goal of this study was to determine the forest structure and estimate biomass accumulation above and below ground in the mangrove forest of Gazi Bay. The western, middle, and eastern forest blocks of the Gazi Bay mangrove forest were investigated for forest structure, whereas the western forest block was determined for biomass accumulation. To calculate below-ground biomass accumulation, in-growth cores of 80 cm long, 20 cm broad, and 60 cm deep were employed. Above-ground biomass accumulation was calculated using data on tree height and stem diameter at breast height (DBH-130). Leaf phenology was observed by tagging shoots. At the start, environmental variables were measured every four months for a year across four mangrove species zones. The linear regeneration sampling approach was used to determine the composition and distribution pattern of natural regeneration (LRS). Salinity revealed a strong negative connection with above-ground biomass accumulation among the soil environment characteristics studied. Sonneratia alba had the highest biomass accretion rate of 10.5 1.9 t ha-1 yr-1 among the four forest zones. Rhizophora mucronata (8.5 0.8 t ha-1 yr-1), Avicennia marina (5.2 1.8 t ha-1 yr-1), and Ceriops tagal (2.6 1.5 t ha-1 yr-1) were the next most abundant species. Above-ground and below-ground biomass accumulation differed significantly among zones (F (3, 8) = 5.42, p = 0.025) and (F (3, 8) = 16.03, p = 0 001), respectively. There was a significant difference in total biomass accumulation across zones (F (3, 8) =15.56, p = 0.001). For the entire forest, a root : shoot biomass accumulation ratio of 2 : 5 was calculated. This study's findings provide more accurate estimates of mangrove carbon capture and storage, which can be used in carbon credit discussions in the emerging carbon market.

“…There are vast and diverse mangrove stands, with 31 species identified that form structurally diverse communities ranging from stunted/dwarf regions to mature forests with canopy heights >40 m (Bunt, Williams, & Clay, 1982;Ellison, 2000). Dominant species include Rhizophora apiculata, R. stylosa, Rhizophora lamarckli, Ceriops australis, Ceriops tagal, and Bruguiera gymnorhiza (Boto & Bunt, 1981;Clough, 1998). The two largest regions of mangrove forest occur at Missionary Bay (approximately 20 km 2 ) and within the Hinchinbrook Channel (approximately 164 km 2 ), which together denote one of the largest neighboring mangrove forests in Australia (Clough, 1998).…”

Cyclones are significant drivers of change within mangrove ecosystems with the extent of initial damage determined by storm severity, location and distribution (exposure), and influenced by species composition and structure (e.g., height). The long‐term recovery of mangroves is often dependent upon hydrological regimes, as well as the frequency of storm events. On February 3, 2011, Tropical Cyclone Yasi (Category 5) made landfall on the coast of north Queensland Australia with its path crossing the extensive mangroves within and surrounding Hinchinbrook Island National Park. Based on a combination of Landsat‐derived foliage projective cover (FPC), Queensland Globe aerial imagery, and RapidEye imagery, 16% of the 13,795 ha of mangroves experienced severe windthrow during the storm. The greatest damage from the cyclone was inflicted on mangrove forests dominated primarily by Rhizophora stylosa, whose large prop roots were unable to support them as wind speeds exceeded 280 km/hr. Classification of 2016 RapidEye data indicated that many areas of damage had experienced no or very limited recovery in the period following the cyclone, with this confirmed by a rapid decline in Landsat‐derived FPC (from levels > 90% from 1986 to just prior to the cyclone to < 20% postcyclone) and no noticeable increase in subsequent years. Advanced Land Observing Satellite (ALOS‐1) Phased Arrayed L‐band Synthetic Aperture Radar (SAR) L‐band HH backscatter also increased initially and rapidly to 5 ± 2 dB (2007–2011) due to the increase in woody debris but then decreased subsequently to −20 ± 2 dB (postcyclone), as this decomposed or was removed. The lack of recovery in affected areas was attributed to the inability of mangrove species, particularly R. stylosa, to resprout from remaining plant material and persistent inundation due to a decrease in sediment elevation thereby preventing propagule establishment. This study indicates that increases in storm intensity predicted with changes in global climate may lead to a reduction in the area, diversity, and abundance of mangroves surrounding Hinchinbrook Island.

“…Mangroves are well known to play many important roles, such as providing carbon and nutrients in coastal areas that support primary and secondary production in nearshore waters, mitigate climate change through sequestration of CO 2 , and protecting human communities from devastating storms and tsunamis (Cebrian, 2002;Clough, 1998;Rivera-Monroy et al, 1995Twilley, 1995). Mangroves are also an important source of food (Abeywickrama and Jayasooriya, 2010;Jariyah et al, 2014;Patil and Chavan, 2013), but studies have largely focused on fish, shrimp, and crabs harvested from and around these ecosystems.…”

The present study aimed to identify the nutritional and antioxidant potential of mangrove fruits of Xylocarpus granatum, Sonneratia alba, and Bruguiera gymnorrhiza growing in Rawa Aopa Watumohai National (RAWN) Park. The protein content of X. granatum fruits (4.50 mg/g) was recorded to be higher than that S. alba (0.93 mg/g) and B. gymnorrhiza (1.09 mg/g), while the fat content in fruits of X. granatum (4.88%), S. alba (4.42%), and B. gymnorrhiza (4.74%) was similar. The total sugar content in fruits of X. granatum (14.8 mg/100 g), S. alba (14.9 mg/ 100 g), and B. gymnorrhiza (13.52 mg/100 g) was also similar. The ascorbic acid content in X. granatum fruit (65 mg/100 g) was higher than that in S. alba (40 mg/100 g) and B. gymnorrhiza (41.87 mg/100 g). However, the fruits of S. alba contained much higher micronutrients of Mn (0.063 mg/g), Zn (0.72 mg/g), and Fe (0.51 mg/g) than those of in X. granatum (0.052, 0.52, and 0.38 mg/g, respectively), and B. gymnorrhiza (0.012, 0.11, and 0.34 mg/g, respectively). Moreover, the fruits of X. granatum contained much higher macronutrients of K and Na compared to fruits of other mangroves. Thus, the findings of this study showed the promising values of all studied mangrove fruits as bio-nutrition and antioxidant sources, and high potentiality to use as renewable food sources for the coastal communities in RAWN Park.
