Two New Ramsar Sites in Bihar

Kanwar Taal (Kabar Taal Lake)
Located in Begusarai district, Kanwar Taal, also known as Kabar Taal Lake, is the largest freshwater oxbow lake in Asia. It lies in the Indo-Gangetic plain and serves as a natural flood reservoir during the monsoon.

Ecological Importance
Acts as a major habitat for migratory and resident waterbirds.

Supports critically endangered species like:

Red-Headed Vulture (CR)

White-Rumped Vulture (CR)

Indian Vulture (CR)

Baer’s Pochard (CR)

Sociable Lapwing (CR)

Major Threats
Overfishing and encroachment.

Agricultural expansion and pesticide pollution.

Siltation leading to habitat degradation.

Fun Fact
During the winter season, Kanwar Taal hosts over 20,000 migratory birds, making it one of the most significant birding sites in eastern India.

Nagi Bird Sanctuary
The Nagi Bird Sanctuary was created after the construction of a dam on the Nagi River in Jamui district. This human-made wetland has now become a thriving ecosystem for both local and migratory species.

Ecological Highlights
Supports endangered migratory birds like the Baer’s Pochard (CR) and Steppe Eagle (EN).

Hosts one of the largest congregations of bar-headed geese in the Indo-Gangetic plains.

Provides nesting and breeding habitats for several native and migratory species.

Conservation Importance
The sanctuary plays a vital role in maintaining biodiversity and climate resilience in the semi-arid regions of southern Bihar.

Nakti Bird Sanctuary
Also situated in Jamui district, Nakti Bird Sanctuary is a man-made wetland formed by the construction of the Nakti Dam. Initially developed for irrigation, it has evolved into a major habitat for aquatic species and migratory birds.

Key Features
Provides shelter for the vulnerable native catfish (Wallago attu).

Hosts large populations of Red-Crested Pochards during the winter season.

Serves as an essential freshwater source for the surrounding agricultural communities.

Ecological Role
Nakti Bird Sanctuary acts as an ecological hotspot supporting avian diversity and sustaining wetland ecosystems through natural water filtration.

Gokul Jalashay
Gokul Jalashay is an oxbow lake located along the southern edge of the Ganga River in Bhagalpur district. Spanning over 448 hectares, it is an integral part of the local cultural and ecological landscape.

Significance
Supports more than 50 bird species, including migratory waterbirds.

The pre-monsoon marshlands serve as important breeding and feeding grounds.

Local communities depend on the wetland for fishing, farming, and irrigation.

Cultural Connection
Every year, a traditional festival is held where locals collectively clean the lake and remove weeds — an excellent example of community-based wetland conservation.

Udaipur Jheel
Udaipur Jheel, located in Bhagalpur district, is another oxbow lake surrounded by the lush Udaipur Wildlife Sanctuary. It spans about 319 hectares and is a critical habitat for a variety of flora and fauna.

Biodiversity
Hosts more than 280 plant species, including Alysicarpus roxburghianus, an endemic species.

Serves as a wintering site for 35+ migratory bird species, including the Common Pochard (VU).

Ecological Role
Udaipur Jheel contributes significantly to groundwater recharge, flood control, and maintaining biodiversity in the Gangetic plains.

Conclusion
The Ramsar sites of Bihar — Kanwar Taal, Nagi Bird Sanctuary, Nakti Bird Sanctuary, Gokul Jalashay, and Udaipur Jheel — represent the state’s commitment to wetland conservation and sustainable development.
These sites are not just ecological treasures but also lifelines for biodiversity, local livelihoods, and climate balance. Protecting them ensures a healthier, more resilient environment for future generations.
