Analyzing impacts of hydrology on natural mangrove regeneration in El Salvador

Brief

Mangrove habitats in Jiquilisco, El Salvador, are vital for both ecological and socio-economic stability, serving as a crucial lifeline for the communities that depend on them. These ecosystems support significant coastal biodiversity, provide nurseries for marine life, enhance bioremediation processes, and protect against coastal erosion. They also play a key role in local livelihoods through cultural wellbeing, fishing, tourism, and the provision of essential resources for building and cooking. Herein, this project aims to restore and protect these valuable mangrove ecosystems across Latin America.

Mangroves challenges and threats

Despite their importance, mangrove habitats face significant challenges, including coastal development pressures and hydrological changes. Issues such as alterations in water flow, salinity, sea surface temperatures, dissolved oxygen levels, sea-level rise due to climate change, and eutrophication have negatively impacted mangrove productivity and biomass. This has resulted in decreased growth, regeneration, and increased mortality rates, leading to a loss of ecosystem service values.

Innovative Research and Technology

To address these challenges, it is imperative to conduct detailed studies on the hydrological and productivity effects on mangroves. Our innovative research utilizes remote sensing technologies, including multispectral satellite imagery, Synthetic Aperture Radar (SAR), and Light Detection and Ranging (LiDAR), to assess the status and changes in mangrove extent, productivity, and biomass, along with the influence of hydrology. By integrating ground-truthing methods, remote sensing can help identify key locations for restoration and conservation initiatives.

Project Implementation

This broad-scale study serves as a critical first step in creating an informed conservation and restoration management plan for mangroves. Ecoresolve will guide future mangrove restoration efforts by identifying specific needs and sites for targeted, micro-scale data collection and monitoring using multispectral UAVs, airborne/UAV LiDAR, and ground-truthing field inventories.

Conclusion

Our ultimate goal is to enhance natural hydrological flows, promoting successful conservation, and fostering natural mangrove regeneration across Jiquilisco Bay. By safeguarding these ecosystems, we aim to benefit the numerous communities that rely on them for their ecological and socio-economic well-being.
