About Rani Jhansi Marine National Park

• Location and Overview

• • • Rani Jhansi Marine National Park is a protected marine area located in the Andaman and Nicobar Islands, India.
    • It covers an area of around 249 sq. km and lies in the southern part of Ritchie’s Archipelago, near well-known islands such as Havelock Island and Neil Island.
    • The park is recognized for its pristine natural environment, calm surroundings, and rich marine biodiversity, making it an important ecological zone in the Bay of Bengal.

• Physical Features and Ecosystem

• • The park is mainly composed of coral reefs, clear lagoons, mangrove forests, and shallow coastal waters.
  • The coral reefs here are highly diverse and act as the foundation of the marine ecosystem, supporting thousands of marine species.
  • The mangrove forests grow along the coastline and serve as natural protectors against erosion while also acting as breeding and nursery grounds for fish.
  • The nearby islands are covered with tropical evergreen vegetation, including trees like padauk and Andaman redwood, which add to the green landscape.

Rani Jhansi Marine National Park Flora and Fauna

• Flora
  • Rani Jhansi Marine National Park has a rich and diverse plant system made up of mangrove forests, tropical rainforests, and coastal vegetation, which together support the park’s fragile ecosystem.
  • Mangrove forests grow densely along the shoreline and act as natural protectors against coastal erosion while also serving as important breeding and nursery areas for many marine organisms.
  • The park also contains lowland evergreen and semi-evergreen rainforests, which remain green throughout the year and support a variety of tropical plant species adapted to humid conditions.
  • Along the coastal zones, littoral vegetation is found where sandy beaches gradually merge into lagoons and coral reef areas, creating a smooth transition between land and sea ecosystems.
  • The surrounding marine environment also supports underwater plant life such as algae and seagrass beds, along with extensive coral reef systems, which form the foundation of the marine ecosystem and provide shelter and nutrients for many species.
• Fauna
  • The park is home to a wide variety of wildlife, making it one of the richest marine biodiversity zones in the Andaman and Nicobar Islands, India.
  • One of the most important species found here is the dugong (sea cow), a rare and endangered marine mammal that is considered the flagship species of the region.
  • The waters of the park also support several species of sea turtles, including olive ridley, green, hawksbill, and leatherback turtles, which come ashore for nesting.
  • Occasional sightings of dolphins and large whales, including blue whales, highlight the ecological richness of the deep waters around the park.
  • Reptiles such as saltwater crocodiles are found in creeks, while land and coastal areas support monitor lizards, forest lizards, and skinks.
  • The park also has rich birdlife, including species like white-bellied sea eagles, kingfishers, herons, and hornbills, which depend on both forest and coastal habitats.
  • Fruit bats are commonly seen and play an important role in pollination and seed dispersal, helping maintain forest regeneration.
  • The coral reef ecosystem supports over 80 species of corals along with a wide range of marine life such as clownfish, angelfish, parrotfish, starfish, sea cucumbers, and reef crabs, making the underwater world highly diverse and vibrant.

• Cleanliness Initiatives: Regular clean-up drives are conducted to remove waste from beaches and marine areas.
• Community Participation: Local communities are involved in conservation activities and sustainable livelihood practices.
• Awareness and Education Programs: Campaigns are conducted to spread awareness about marine biodiversity conservation.
• Support from Local Communities: Locals help in reporting illegal activities like poaching and fishing.
• Scientific Monitoring: Continuous monitoring of coral health, water quality, and marine biodiversity is carried out.
• Research and Data Collection: Scientific studies help in understanding ecosystem changes and improving conservation strategies.
• Improved Management Planning: Data-driven policies are used to ensure long-term protection of the ecosystem.

Major Threats in Rani Jhansi Marine National Park

• Overfishing and Destructive Fishing Practices: Indiscriminate and excessive fishing is damaging coral reef ecosystems and significantly reducing fish populations.
• Poaching and Illegal Collection: Activities like shell diving and sea cucumber collection are putting immense pressure on marine biodiversity.
• Tourism Pressure: Easy accessibility from Port Blair has led to a rapid increase in both domestic and international tourists, causing stress to fragile ecosystems.
• Habitat Disturbance from Settlements: Expanding human settlements along park boundaries are disturbing natural habitats and wildlife.
• Pollution and Waste Disposal: Dumping of domestic waste into the sea is harming coral reefs and affecting marine organisms.
• Deforestation and Plantation Activities: Tree-felling and plantation practices have contributed to habitat degradation within and around the park.
• Historical Timber Extraction: Large-scale logging by companies like Wimco and Andaman Timber Industries during the 1960s-70s caused long-term environmental damage.
• Past Logging Activities: Continued forest department logging until 2002 (stopped after a Supreme Court order) also led to habitat loss.
• Rising Human Dependence on Resources: Increasing reliance on marine and forest resources by nearby populations is adding pressure on the ecosystem.
