The ecological implications of plastic pollution on ecosystem processes and human beings are well known. Increasing use of single-use plastic, poor waste management, lack of recycling, and fragmentation of plastic have made it ubiquitous, posing a grave threat to species across trophic levels. Over 1500 species ranging from invertebrates to vertebrates are impacted by plastic pollution. Globally, plastic in marine environments has been reported extensively whereas terrestrial ecosystems have remained understudied. The effects of plastic pollution are alarming, resulting in … Read More
Rampant hunting and habitat loss changed the fate of two large Indian carnivores; the Asiatic lion (Panthera leo persica) and the Asiatic cheetah (Acinonyx jubatus venaticus), the latter of which was driven to extinction in India in 1952. The last and only population of Asiatic lions in the wild is now confined to the Gir Forest in Gujarat and its environs. For years experts have been urging the authorities to translocate a subset of the … Read More
The Northern River Terrapin (Batagur baska) is a large-sized species of aquatic turtle with an average carapace length of 60cm. They are known to nest on beaches close to river mouths or on river islands. Once abundant in South Asia (India, Bangladesh, and Myanmar) till the 1900s, the Northern River Terrapin is now listed as Critically Endangered by the Red List of the International Union for Conservation of Nature (IUCN). Wild terrapin populations precipitously declined due to the … Read More
The menace of illegal wildlife trafficking is primarily understood in the context of terrestrial species from a layperson’s perspective. However, the definition of ‘wildlife’ under the Wild Life (Protection) Act, 1972 (WLPA) includes aquatic life and their habitat. The WLPA, in its current form, protects marine species like sea turtles, sea cucumber, sea fans, sea horses, some species of sharks and rays, corals, mollusca, etc., under its Schedules. In addition to these, ITCHS Based Import Export Policy provides for … Read More

A review paper focuses on the importance of the threatened Myristica freshwater swamps, their ecology, and prior research on them. It focuses on the need for conservation initiatives to save the last few Myristica swamps in India.
What are Myristica swamps?
Myristica swamps are freshwater swamps predominated by members of the Myristicaceae family. These forests are characterized by trees with large protruding roots jutting out of waterlogged soil which remains inundated throughout the year. They have evolved over … Read More
Illegal wildlife trade (IWT) is a major threat to numerous wildlife species and ecosystems across the world, with established global links to organised criminal activities and an annual value encompassing billions of dollars. Media reports function as an untapped reservoir of publicly available records that can be utilised to understand the nature and scale of this trade.
A report, “Media-Reported Wildlife Poaching and Illegal Trade in India 2020,” was published by the Wildlife Conservation Society-India. It provides a comprehensive overview … Read More
What is a corridor?
In the sphere of conservation biology, a wildlife corridor is a strip of habitat that connects two wildlife source populations and serves as a movement path for wild animals in search of resources such as food, habitat and mates. In a larger landscape, consisting of many source populations, one can have a network of corridors, connecting pairs of source populations so that they are connected directly or indirectly. Together these populations constitute a metapopulation.
For several … Read More
On July 11th, 2020, Mint, an Indian business newspaper, carried a centrepiece titled, “The Big Himalayan Earthquake Is Coming”. This story quoted several scientific studies that warned of the risks posed to cities, towns, and hundreds of villages in the Himalayan region from a future earthquake that has been predicted with a high degree of certainty. The seismological research supporting the key premise of this article is impeccable, has been subject to examination, validation, and peer-review, and therefore … Read More
The dramatic decline of vultures remains one of the poignant stories of wildlife conservation in India. The primary reason was a nonsteroidal anti-inflammatory veterinary drug (NSAID), diclofenac. Being a pervasive drug, diclofenac would remain in cattle even after their death and be indirectly consumed by vultures, which then suffer fatal consequences. Consumption of diclofenac caused gout and kidney failure in three species of Gyps vultures; White-rumped (Gyps bengalensis), Long-billed (Gyps indicus), and Slender-billed (Gyps tenuirostris… Read More
