Delhi-NCR’s Richest Bird Park Faces Growing Urban Encroachment as Concrete Development Threatens Fragile Ecosystem
Rising violations in the eco-sensitive zone around Sultanpur National Park spark fresh concerns over habitat loss, migratory birds and long-term conservation in the National Capital Region.
One of Delhi-NCR’s most important bird habitats, Sultanpur National Park, is facing mounting pressure from rapid urban expansion as illegal and unregulated construction continues to spread around its protected boundaries. Conservationists warn that unchecked development could permanently alter one of northern India’s richest bird ecosystems.
According to the latest inspections, authorities have identified 183 violations of eco-sensitive zone (ESZ) regulations surrounding the park, including 48 new violations since the previous assessment. The findings suggest that residential and commercial construction is steadily advancing toward the park despite environmental safeguards intended to protect the fragile habitat.
Located in Gurugram, Sultanpur National Park is Haryana’s first Ramsar Site, recognised internationally as a wetland of ecological importance. Every winter, it becomes a refuge for thousands of migratory birds arriving via the Central Asian Flyway, alongside hundreds of resident bird species that depend on its wetlands, grasslands and woodlands for breeding and feeding.
Environmental experts say the expansion of roads, housing projects and commercial infrastructure around the park is fragmenting habitats while increasing noise, pollution and human activity. Such disturbances can disrupt nesting behaviour, reduce food availability and discourage migratory birds from returning to traditional breeding and wintering grounds.
The concerns come just weeks after the release of the Delhi Bird Atlas, which highlighted the exceptional biodiversity of the region. The report found that Delhi hosts 471 bird species, making it the world’s second-richest national capital for avian diversity after Nairobi. Scientists say preserving neighbouring wetlands and protected areas such as Sultanpur is essential to maintaining that remarkable biodiversity.
Conservationists are urging governments in Haryana and the National Capital Region to strengthen enforcement of eco-sensitive zone regulations, halt illegal construction and adopt long-term land-use planning that balances urban growth with environmental protection. They argue that once natural habitats surrounding protected areas are lost, restoration becomes increasingly difficult and costly.
Experts also stress that Sultanpur’s ecological significance extends beyond birdwatching. The park supports wetland health, biodiversity conservation, groundwater recharge and environmental education while serving as a vital stopover for migratory species travelling thousands of kilometres each year. Protecting its surrounding landscape is therefore considered essential not only for wildlife but also for the ecological resilience of the rapidly expanding Delhi-NCR region.
