The ecological significance of mangroves lies in their role as crucial coastal ecosystems. They provide habitats for diverse marine and terrestrial species, acting as nurseries for fish and other wildlife. Mangroves also protect coastlines from erosion and storm surges, thus mitigating the impacts of climate change. Additionally, they contribute to carbon sequestration, storing large amounts of carbon in their biomass and soil, which helps in combating global warming. Their root systems filter pollutants and improve water quality, making them vital for both local and global ecosystems.
