Planted mangroves can store up to 75% of the carbon stocks found in intact mature stands

Forty years of data from 684 planted mangrove stands worldwide reveal that planted stands can store 71 to 73% of biomass carbon (C) stock ~20 years after planting. Although soil C stocks in planted mangroves plateau after an initial 25% increase in the first 5 years, planting still causes a land use change that effectively prevents further C losses. Rhizophora spp. in mixed-species planted stands could increase C sequestration to reach the biomass C stocks of intact stands although fast growing (<10 years to peak biomass) pioneer genera have important applications for nature-based solutions. Overall, results strongly suggest that mixed-species planting should be prioritized to maximize C accumulation (Bourgeois et al., 2024).

Logistic growth models of the C stock buildup ratios R over time in planted mangroves relative to intact mangrove stands, and visualization of the worldwide C stock buildup values (R) predicted by these models. (A) Comparative view of the C stock buildup ratio (R) logistic growth models over time in the AGB (gray), BGB (blue), and soil (orange) in planted mangroves (logarithmic scale for the C stock buildup ratio axis). For each model, the number of observations (n), coefficient of determination (R2), and the probability (prob) are indicated; (B) violin plots of the worldwide predicted C stock buildup (megagrams per hectare, logarithmic scale) in the AGB, BGB, and soil at years 1, 5, 10, 20, 30, and 40 following planting. Mean predicted C stocks are indicated by large circles, while the mean global intact C stocks are indicated by dashed lines for comparison. The predicted C stocks were calculated by multiplying the ratios R at age 1, 5, 10, 20, 30, and 40 years following planting to each intact mangrove C stock data found in the literature for the AGB.

  1. I am interested in obtaining a master in biodiversity and climate change with emphasis in mitigating the threats on mangrove especially in my country Liberia. I would love to do master in the Philippines but any time I plan it can’t materialise. I have obtained a post Graduate Diploma in Fish Quality Assurance Management and want to enhance my studies by obtaining a master.
