Why in News: Odisha has begun the process to declare the Rushikulya rookery in Ganjam district as a Biodiversity Heritage Site, recognising its global importance as a major nesting ground for Olive Ridley sea turtles and a lifeline for local communities.
Rushikulya rookery: a unique coastal ecosystem
The Rushikulya rookery stretches for about 10 km from New Podampeta to Agasti Nuagaon along the river mouth and adjoining sea beach in Ganjam district. It is recognised as one of the world’s major mass nesting, or Arribada, sites where thousands of Olive Ridley sea turtles come ashore to lay eggs every year. This fragile coastal belt also supports migratory and resident birds, diverse plant species and a rich estuarine environment.
The surrounding Prayagi reserve forest, spread over nearly 415 hectares near the sea mouth, further enhances the ecological value of the landscape. This forest harbouring many native and medicinal plants links the marine and terrestrial habitats, creating a mosaic of biodiversity that is rare along India’s eastern coast.
Why biodiversity heritage status matters
The Odisha government, through the Odisha Biodiversity Board, has initiated the process to confer Biodiversity Heritage Site status on around 747 hectares in and around the rookery under Section 37 of the Biological Diversity Act, 2002. Scientists and researchers have already conducted a preliminary survey along the river mouth and sea beach after the Berhampur forest division submitted a formal proposal. This move signals a policy-level commitment to long-term protection of the rookery’s ecology and its associated cultural landscape.
Confluence of nature, culture and faith
Rushikulya is not only an ecological asset but also a cultural and spiritual space. The river is closely associated with local rituals, festivals and traditional practices that have evolved around its seasonal rhythms and natural cycles. Near the river mouth stands the Bateswar Temple, which embodies a convergence of sacred ecology and cultural heritage amid a biodiverse landscape.
What are Biodiversity Heritage Sites ?
Biodiversity Heritage Sites (BHS) are unique, ecologically fragile, and biodiversity-rich areas—terrestrial, coastal, or inland waters—designated under Section 37 of India’s Biological Diversity Act, 2002. They harbor rare, threatened species and high endemism, emphasizing conservation without restricting local community usage
Key Features of Biodiversity Heritage Sites:
- Designation: Declared by State Governments in consultation with local bodies (Panchayats/BMCs).
- Significance: These sites often contain high species richness, wild ancestors of cultivated plants, and significant cultural/aesthetic values.
- Purpose: To enhance the quality of life of local communities and preserve unique ecosystems.
- Notable Examples in India:
- Nallur Tamarind Grove (Karnataka): India’s first BHS (2007), known for ancient tamarind trees.
- Majuli Island (Assam): Largest river island with unique aquatic/terrestrial biodiversity.
- Aravalli Biodiversity Park (Haryana): Urban green space.
- Chilika Lake (Odisha): Major habitat for migratory birds.
- Gupteswar Forest (Odisha): Rich in biodiversity and sacred groves.
- Ambaragudda (Karnataka): Features rare Shola vegetation.

Answer Key and Explanations
Ans 1. (b) 1 and 3 only
-
Statement 1 is correct: The passage states the Rushikulya rookery is in the Ganjam district and is a major mass nesting (Arribada) site for Olive Ridley turtles.
-
Statement 2 is incorrect: It is located along the Rushikulya river mouth, not the Mahanadi river.
-
Statement 3 is correct: The text mentions the surrounding Prayagi reserve forest links the marine and terrestrial habitats.
Ans 2. (b) 3 only
-
Statement 1 is incorrect: BHS are designated under Section 37 of India’s Biological Diversity Act, 2002 (not the EPA, 1986) by State Governments (not the Central Government).
-
Statement 2 is incorrect: The passage explicitly notes that BHS designation emphasizes conservation without restricting local community usage.
-
Statement 3 is correct: Nallur Tamarind Grove in Karnataka was India’s first BHS, declared in 2007.
Ans 3. (b) Only two pairs
-
Pair 1 is correctly matched: Ambaragudda (Karnataka) features rare Shola vegetation.
-
Pair 2 is incorrectly matched: Majuli Island is the largest river island, but it is located in Assam, not West Bengal.

Darknet
Definition:
Darknet, also known as dark web or darknet market, refers to the part of the internet that is not indexed or accessible through traditional search engines. It is a network of private and encrypted websites that cannot be accessed through regular web browsers and requires special software and configuration to access.
The darknet is often associated with illegal activities such as drug trafficking, weapon sales, and hacking services, although not all sites on the darknet are illegal.
Examples:
Examples of darknet markets include Silk Road, AlphaBay, and Dream Market, which were all shut down by law enforcement agencies in recent years.
These marketplaces operate similarly to e-commerce websites, with vendors selling various illegal goods and services, such as drugs, counterfeit documents, and hacking tools, and buyers paying with cryptocurrency for their purchases.
