Abstract

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.

墨西哥东南部红树林的地上生物量和碳储量

红树林对全球碳固存的贡献加强了估算这些系统生物量的必要性。该研究的目的是确定墨西哥东南部红树（Rhizophora mangle）、Avicennia germinans 和 Laguncularia racemosa 的地上生物量储存量，并量化碳和 CO2e 含量。根据气候行动保护区发布的《墨西哥森林议定书 2.0 版》方法，在 930 公顷的红树林植被中随机选择并建立了 130 个圆形地块，并测定了地上生物量和储存的碳。红树林的密度为每公顷 3515 ± 428.5 个个体。三个物种的地上生物量为 120.5 兆克/公顷-1。L. racemosa 的生物量为 99.5 兆克/公顷-1，占总生物量的 82.6%。R. mangle 的生物量为 20.33 兆克/公顷-1，A. germinans 的生物量为 0.32 兆克/公顷-1。树木中保留的碳总量为 60.25 兆克 C（公顷-1）和 221.1 兆克 CO2e（公顷-1）。其中，Laguncularia racemosa 产生的 CO2e 最多。红树林面积积累了 112,065 兆克地上生物量。这些生物量所含的碳相当于 205,623 兆克 CO2e。这种红树林通过减少温室气体为减轻全球气候变化的影响做出了贡献。

期刊介绍： Resources (ISSN 2079-9276) is an international, scholarly open access journal on the topic of natural resources. It publishes reviews, regular research papers, communications and short notes, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and methodical details must be provided so that the results can be reproduced. There are, in addition, unique features of this journal: manuscripts regarding research proposals and research ideas will be particularly welcomed, electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Subject Areas: natural resources, water resources, mineral resources, energy resources, land resources, plant and animal resources, genetic resources, ecology resources, resource management and policy, resources conservation and recycling.
