ऐतिहासिक पृष्ठभूमि
मुख्य प्रावधान
10 points- 1.
Biodiversity Hotspot: Forms a major part of the Indo-Burma Biodiversity Hotspot, one of the world's most critical and threatened biodiversity regions, known for its high species richness.
- 2.
High Endemism: Home to a large number of endemic species of flora and fauna, meaning they are found nowhere else in the world, making it a unique evolutionary theatre.
- 3.
Diverse Ecosystems: Features a wide range of ecosystems including tropical rainforests, temperate forests, alpine meadows, wetlands, and grasslands, supporting varied life forms.
- 4.
Major Rivers: Drained by major river systems like the Brahmaputra, Barak, and their numerous tributaries, supporting unique aquatic biodiversity and providing vital ecosystem services.
- 5.
Rich Flora: Exceptionally rich in orchids (over 800 species), rhododendrons, bamboos, and medicinal plants. It is considered a center of origin for many cultivated plants like rice, citrus, and tea.
- 6.
Diverse Fauna: Hosts iconic species like the One-horned Rhinoceros, Hoolock Gibbon (India's only ape), Clouded Leopard, various hornbills, and a high diversity of reptiles, amphibians, fish, and insects.
- 7.
Tribal Communities: Home to numerous indigenous tribal communities with rich traditional ecological knowledge systems that often contribute to biodiversity conservation through sacred groves and sustainable practices.
- 8.
Threats: Facing significant threats from deforestation, shifting cultivation (Jhum), large-scale infrastructure development (dams, roads), illegal wildlife trade, and the impacts of climate change.
- 9.
Conservation Efforts: Presence of numerous National Parks (e.g., Kaziranga, Manas, Namdapha), Wildlife Sanctuaries, and Biosphere Reserves, along with community-led conservation initiatives.
