Indian Crested Porcupine
Why in News?
The Indian Crested Porcupine (Hystrix indica) is in the news because it has recently emerged as a significant agricultural pest in the Kashmir Valley, specifically targeting high-value saffron corms.
Biological Features
- Largest Rodent: It is the largest rodent found in the Indian subcontinent, weighing up to 18 kg.
- Quill Defence: Its back is covered in sharp black-and-white quills (modified hairs). Contrary to myth, it cannot "shoot" quills; instead, it raises them and charges backward into threats.
- Nocturnal Lifestyle: They are primarily active at night, spending about 7 hours foraging and staying in deep burrows during the day.
- Burrow Architects: They dig elaborate burrows up to 13 metres long, often sharing them with other species like bats and reptiles.
- Range: Found across South and Central Asia, including India, Nepal, Pakistan, Iran, and Saudi Arabia.
- Adaptability: They thrive in diverse environments, from arid deserts and rocky hillsides to tropical forests and agricultural farmlands.
- Generalist Foragers: Mostly herbivorous, eating roots, bulbs (geophytes), fruits, and grains.
- Bone Gnawing: They often chew on bones to obtain calcium needed for quill growth.
- Habitat Modifiers: By digging for tubers, they act as soil modifiers, influencing local ecosystem dynamics.
- IUCN Red List: Categorised as Least Concern (LC) due to its wide range and stable population.
- Wildlife Protection Act (India):
- Historically listed under Schedule IV.
- Upgraded to Schedule I (highest protection) under the 2022 Amendment, granting it "Z-class" security from hunting.
- Threats: Despite its pest status, it faces threats from habitat loss, road accidents, and hunting for medicinal use or bushmeat.
