grounds, and shelter to a large variety of marine organisms.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">They also protect coastlines from erosion and reduce the impact of strong waves and storms.<\/span><\/li>\n<\/ul>\n<p><b>Mangrove and Seagrass Ecosystems<\/b><span style=\"font-weight: 400;\">: Mahatma Gandhi Marine National Park supports 13 species of <\/span><strong><a href=\"https:\/\/vajiramandravi.com\/upsc-exam\/mangroves\/\" target=\"_blank\">mangroves<\/a><\/strong><span style=\"font-weight: 400;\"> and 5 species of seagrasses.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mangrove forests stabilize coastal areas, prevent erosion, and act as nursery grounds for fish and crustaceans.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Seagrass meadows provide feeding grounds for dugongs and sea turtles and contribute significantly to carbon sequestration.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The close association of coral reefs, mangroves, and seagrass ecosystems creates a highly productive ecological network that supports numerous species and strengthens ecosystem resilience.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Both mangroves and seagrasses act as important carbon sinks, thereby supporting climate change mitigation efforts.<\/span><\/p>\n<h2><b>Mahatma Gandhi Marine National Park Floral Diversity<\/b><\/h2>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The park contains approximately 298 spermatophytic taxa and several rare plant species.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Mangrove vegetation is dominated by species such as Rhizophora mucronata, Bruguiera gymnorhiza, Avicennia officinalis, Heritiera littoralis, and Xylocarpus granatum.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Terrestrial vegetation includes Andaman Padauk, Andaman Bullet Wood, Silk Cotton Tree, Dipterocarp species, bamboo, orchids, cycads, and ferns.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The discovery of the wild rice species Oryza andamanica highlights the importance of the park as a repository of genetic diversity.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">The rich floral diversity contributes significantly to ecological stability and habitat formation.<\/span><\/p>\n<h2><b>Mahatma Gandhi Marine National Park Faunal Diversity<\/b><\/h2>\n<p><b>Mahatma Gandhi Marine National Park <\/b><span style=\"font-weight: 400;\">is home to an exceptionally rich variety of marine and terrestrial fauna.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Its waters support around 282 species of fish along with numerous species of

style=\"font-weight: 400;\">Despite its ecological importance, the park faces several environmental challenges.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Climate Change and Coral Bleaching<\/b><span style=\"font-weight: 400;\">: Rising sea surface temperatures have caused repeated coral bleaching events, particularly in 1998, 2010, and 2016. Coral bleaching weakens reef ecosystems and can result in large-scale coral mortality.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Marine Plastic Pollution<\/b><span style=\"font-weight: 400;\">: Recent studies indicate that plastic constitutes nearly 60 percent of marine litter in the coral reef areas of the Andaman and Nicobar Islands. Abandoned fishing nets and other plastic waste often entangle marine animals or are mistakenly consumed by them.<\/span><\/li>\n<\/ul>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Tourism and Human Disturbance<\/b><span style=\"font-weight: 400;\">: Increasing tourism activities also exert pressure on fragile marine ecosystems. Unregulated snorkeling, diving, and boat anchoring can damage coral reefs and disturb wildlife habitats.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Sedimentation and Nutrient Enrichment<\/b><span style=\"font-weight: 400;\">:\u00a0 Agricultural runoff and sedimentation further threaten coral health by reducing water quality and promoting excessive algal growth. In addition, outbreaks of Crown-of-Thorns Starfish can cause extensive destruction of coral reefs.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Natural Disasters<\/b><span style=\"font-weight: 400;\">: Natural disasters such as cyclones, earthquakes, and tsunamis periodically affect the region. The 2004 Indian Ocean Tsunami caused significant damage to coastal and marine ecosystems throughout the Andaman Islands.<\/span><\/li>\n<\/ul>\n<h2><b>Mahatma Gandhi Marine National Park Conservation
