“…The density of trees in Úrsulo Galván, Tabasco (3515 ind ha −1 , DBH ≥ 5 cm) was higher than that reported for mangroves on the Tabasco coast (1184 ind ha −1 , DBH > 10 cm) [33], for the Pantanos de Centla and Campeche (2875 ind ha −1 , DBH > 5 cm) [49], for Laguna de Términos (3095 ind ha −1 , DBH ≥ 2.5) [50], for the La Encrucijada Reserve, Chiapas (2103 ind ha −1 , DBH > 2.5 cm) [10], and for Ciudad del Carmen, Campeche (1400 ind ha −1 , DBH > 2.5 cm) [51]. The mangrove species recorded in Úrsulo Galván public land are similar in density to those reported by Agraz-Hernández et al [15] for basin-type mangroves (3580 ind ha −1 ), greater than that reported for riverine mangroves (1730 ind ha −1 ), and lower that for fringe mangroves (5930 ind ha −1 ). The higher density of L. racemosa coincides with that found in basin mangroves where, with greater distance inland, the tidal influence decreases, and the density of R. mangle diminishes, while that of L. racemosa and A. germinans increases [32].…”

“…In Mexico, the average carbon stock for Chiapas, Tabasco, Campeche, and Veracruz is 70 Mg C ha −1 [14]. In Nayarit, the average carbon stock is 36.22 Mg C ha −1 [15]. At a global level, the aboveground biomass of mangroves has been estimated at 2.83 Pg (dry weight), with 184.8 Mg ha −1 being the average per unit area [4,16].…”

“…There are differences in biomass storage according to the physiological type of the mangrove [31]. This is because mangroves present variability in their structure due to the environmental, physical, and chemical parameters of the water and the substrate in which they grow [15]. According to Lugo and Snedaker [32], mangrove physiognomic types are classified as Riverine, Fringe, Basin, Overwash, and Dwarf.…”

“…Overwash mangroves are located on bars, islands, and isolated islets and are constantly affected by tidal currents. The dwarf mangrove type is characterized by its scant structural development as a consequence of being removed from sources of nutrients from rivers or being found in areas of intense evaporation, which generates hypersalinity in the sediment [15].…”

The aboveground contributions of mangroves to global carbon sequestration reinforce the need to estimate biomass in these systems. The objective was to determine the aboveground biomass storage and quantify the carbon and CO2e content in Rhizophora mangle, Avicennia germinans, and Laguncularia racemosa present in southeastern Mexico. Based on the Forest Protocol for Mexico Version 2.0 methodology, published by Climate Action Reserve, 130 circular plots were randomly selected and established in an area of 930 ha of mangrove vegetation, and the aboveground biomass and stored carbon were determined. The mangrove had a density of 3515 ± 428.5 individuals per hectare. The aboveground biomass of the three species was 120.5 Mg ha−1. The biomass of L. racemosa was 99.5 Mg ha−1, which represents 82.6% of the total biomass. The biomass of R. mangle was 20.33 Mg ha−1, and that of A. germinans was 0.32 Mg ha−1. The total carbon retained in the trees was 60.25 Mg C ha−1 and 221.1 Mg CO2e ha−1. Laguncularia racemosa generated the highest contributions of CO2e. The area of mangroves accumulated 112,065 Mg of aboveground biomass. The carbon contained in this biomass corresponds to 205,623 Mg CO2e. This mangrove contributes to mitigating the effects of climate change globally through the reduction in greenhouse gases.

“…While the calculated EVs for the North Pacific were 401.6 USD (WB) and 293.5 tCO 2 e USD (VM) (Table 7), the estimates for BT and El Sargento were 1.24 and 1.7 times higher. According to Agraz-Hernández et al (2020), the EV of avoided CO 2 emissions in the reserve amounts to 4431,826.7 USD, based on a market price per tCO 2 e of 5.5 USD and a TA of 3280 ha. This area is higher than that of BT (362.8 ha) and El Sargento (443.31 ha), as well as the tCO 2 e price considered in this study (WB and VM, 1.9 and 2.6 USD, respectively).…”

Introduction: Mangroves provide environmental goods and services that mitigate climate change. Objective: To estimate the economic value of the carbon stock in the aboveground biomass of mangroves in Bahía del Tóbari (BT) and El Sargento in Sonora. Materials and methods: Field research were conducted in 2014 and 2015 in 16 plots (10 x 10 m). Biomass of Laguncularia racemosa (L.) Gaertn, Rhizophora mangle L. and Avicennia germinans(L.) L. was determined with specific allometric equations. Carbon stocks and avoided CO2e emissions were estimated with conversion factors 0.5 and 3.7, respectively; these data represented the 2015 baseline. The 2020 estimates included changes in mangrove cover. The economic value was determined using the marginal carbon abatement cost method. Results and discussion: The 2015 baseline indicated reserves of 52.1 MgC∙ha-1 and 191.2 tCO2e∙ha-1 for BT, and 71.7 MgC∙ha-1 and 263.2 tCO2e∙ha-1 for El Sargento. By 2020 avoided emissions of 69 368.2 tCO2e∙TA-1 (TA= 362.79 ha) were estimated for BT and 116 696tCO2e∙TA-1(TA = 468.32 ha) for El Sargento. Economic values of these emissions were 131 799.5 USD (World Bank) and 180 357.2 USD (voluntary carbon market) for BT and 221 722.2 USD (World Bank) and 303 409.4 USD (voluntary carbon market) for El Sargento. Conclusions: The highest estimates of C reserves and economic value were recorded at El Sargento. Compared to other studies in the region, both sites had higher avoided CO2e emissions.

[Objetivo]. Se evaluó el manglar de Chacarita en el Pacífico Central de Costa Rica, a través de la composición florística y las poblaciones de moluscos asociados de interés comercial, con el fin de proponer actividades de aprovechamiento sustentables en el manglar. [Metodología]. Mensualmente y durante un año, se realizaron visitas al área de estudio, con el propósito de establecer una base florística de árboles de mangle y medir el almacenamiento de carbono en el lugar, además, de recolectar moluscos bivalvos para analizar el estado de las poblaciones, con base en las abundancias de organismos hallados y otras características como las longitudes y la masa de estos. En los mangles, se obtuvo el diámetro de la altura de pecho (DAP en cm), la altura (m), el índice de valor de importancia (IVI) y las reservas de carbono (Mg C·ha-1). En cuanto a los moluscos, se examinaron cuatro especies de interés comercial, evaluando la longitud (cm), la masa (g) y el índice gonadosomático. Finalmente, se realizaron valoraciones económicas de los datos obtenidos en el manglar, del turismo e información histórica de pesca para el acopio de Chacarita. [Resultados]. Se hallaron cinco especies de mangles, Rhizophora mangle, Rizophora racemosa, Laguncularia racemosa, Avicennia germinans y Pelliciera rhizophorae; P. rhizophorae fue la de mayor índice de valor de importancia. Se obtuvo un almacenamiento de carbono equivalente a 78.49 Mg C·ha-1. Se contabilizaron 357 organismos, de los cuales el 18 % correspondió a Anadara similis, 37.5 % a Anadara tuberculosa, 41.46 % a Leukoma spp. y 3.08 % a Mytella guyanensis. Tomando en cuenta el valor económico de las reservas de carbono y los moluscos bivalvos presentes en los muestreos, se obtuvieron valoraciones económicas de 9812.63 USD·ha-1 y 28 USD·ha-1, respectivamente. [Conclusiones]. Las bajas densidades poblacionales de moluscos, especialmente del género Anadara, hacen necesario establecer medidas de gestión que permitan recuperar las poblaciones de estos. La presente investigación propone actividades de aprovechamiento sustentables, como turismo comunitario con fines educativos y culturales.
