4. National Forest Martyrs Day: Recently,
National Forest Martyrs Day was observed across India, during which tributes were offered to Forest Department personnel who sacrificed their lives in the line of conservation duty.
- About the National Forest Martyrs Day: Observed every year on September 11 to honor the sacrifices of those who gave their lives protecting India’s forests and wildlife.
- The day recognizes forest personnel and environmental protectors who face risks while safeguarding natural resources.
- Historical Background: The observance is rooted in the Khejarli Massacre of 1730 in the Marwar Kingdom.
- Maharaja Abhai Singh ordered the felling of Khejri trees from Khejarli village for his palace construction.
- The Bishnoi community, led by Amrita Devi Bishnoi, resisted by hugging trees to protect them.
- Amrita Devi and around 363 villagers were killed while defending the trees.
- This sacrifice later inspired conservation movements like the Chipko Movement, shaping India’s environmental ethos.
- In 2013, the Ministry of Environment, Forest and Climate Change officially declared September 11 as National Forest Martyrs Day.
5. Bent-Toed Gecko: Recently, a new species of
bent-toed gecko was recorded in the montane forests of central Assam, adding to the region’s biodiversity.
- About Bent-Toed Gecko (Cyrtodactylus vanarakshaka): Belongs to the Cyrtodactylus khasiensis group.

- Found on the forested slopes of Jatinga in Dima Hasao, an ecological transition zone within the Barail Hills.
- Named in honor of the Assam Forest Department.
- The name derives from Sanskrit: vana (forest) and rakshaka (protector), signifying “forest protector.”
- Known for endemism and restricted distribution.
- With this discovery, the number of Cyrtodactylus species in Assam rises to five.
6. Biodiversity Heritage Site: Recently, the Karnataka government officially designated an ~8.61-acre area in the
Cantonment Railway Colony,
Bengaluru, as a
Biodiversity Heritage Site.
- About Biodiversity Heritage Sites: Biodiversity-rich areas that play a vital role in local ecosystems and are conserved and managed by communities.
- They are unique ecosystems known for: Rich diversity of wild and domesticated species or their sub-varieties.
High levels of endemism.
- Presence of rare, threatened, keystone, or evolutionarily significant species.
- Occurrence of wild ancestors of cultivated/domesticated species.
- Fossil beds or sites of past biological importance with cultural, ethical, or aesthetic value.
- They may exist across terrestrial, aquatic, coastal, inland, or marine ecosystems.
- Legal Provisions: Declared under Section 37 of the Biological Diversity Act, 2002 by State Governments, in consultation with local bodies. Declaration of a BHS does not restrict traditional practices or usages of local communities, unless voluntarily decided by them.
- The main aim is to improve the quality of life of local communities through the conservation of these ecologically and culturally significant sites.
7. Designer Clownfish: Recently, scientists at the
National Bureau of Fish Genetic Resources (NBFGR) developed
designer clownfish through cross-breeding for the ornamental trade and community aquaculture.
- About Clownfish: Also known as anemonefish, they are small marine fish characterized by their bright orange bodies with white stripes.
- Habitat: Prefer shallow coral reefs in the tropical Pacific and Indian Oceans.
- Global Distribution: Found from the Red Sea to French Polynesia, including Japan and Australia.
- India Range: Present in the Andaman-Nicobar Islands, Lakshadweep, and Gulf of Mannar–Palk Bay.
- Symbiosis: Live in mutual association with sea anemones, gaining protection while offering defense to the host.
- Hermaphroditism: All individuals are born male; the dominant male can transform into a female.
- Conservation: IUCN Status: Least Concern.
8. Cicadas: Recently, ecologists noted the
tentative return of cicadas to Silent Valley National Park, which may indicate either ecological recovery or environmental disruption.
- About Cicadas: These are hemipteran insects recognized for their loud, complex, and species-specific acoustic signals (songs).
- Global Diversity: India and Bangladesh together have the highest cicada diversity in the world, followed by China.
- Survival Strategy: Their emergence timing often coincides with periods when predators are dormant, improving survival chances.
- Habitat: Mostly canopy dwellers, commonly found in natural forests with large trees.
- Over 3,000 species globally, divided into two groups: Annual Cicadas and Periodical Cicadas
- Ecological Significance: Help prune mature trees and aerate soil. After death, their bodies enrich the soil with nitrogen, benefiting tree growth.
