The wetlands that keep Kashmir alive

By Mauzam Bakshi

Every year, with the onset of winter, Kashmir Valley welcomes one of the most remarkable natural events on Earth. Tens of thousands of migratory birds arrive from the Arctic, Siberia, Kazakhstan, Mongolia and other parts of Central Asia after travelling thousands of kilometres. Their arrival is not merely a seasonal spectacle but a testimony to the ecological importance of Kashmir’s wetlands, which form a vital link in the Central Asian Flyway (CAF) — one of the world’s nine major migratory bird flyways.

The Central Asian Flyway extends across thirty countries and supports the migration of more than six hundred bird species, including numerous globally threatened species. Within this vast international network, Kashmir occupies a strategically important position. Wetlands such as Hokersar, Wular Lake, Haigam, Shallabugh, Mirgund and Anchar  serve as essential wintering and stopover habitats where birds rest, feed and replenish the energy reserves needed to continue their arduous journeys.

Unfortunately, wetland conservation is often viewed in isolation, with attention focused on individual sites. Modern ecological science, however, tells a different story. These wetlands function as an interconnected network. Their ecological value lies not only in their individual health but also in their collective functioning. Consequently, the degradation of even one major wetland can weaken the resilience of the entire flyway.

This concept is well established in migration ecology through what scientists call the “Stepping-stone theory.” Long-distance migratory birds cannot fly continuously for thousands of kilometres without stopping. They depend on a chain of suitable wetlands spaced along their migration route. Each wetland acts as a biological refuelling station, providing food, shelter and protection from predators and harsh weather.

If one of these stations deteriorates because of pollution, siltation, encroachment, excessive weed growth or changes in hydrology, the birds are forced to crowd into neighbouring wetlands or undertake longer flights without adequate nourishment. This increases stress, reduces survival rates and ultimately affects breeding success thousands of kilometres away in their northern breeding grounds.

International studies published in journals have repeatedly shown that the loss or degradation of key stopover sites results in measurable declines in migratory bird populations. The Ramsar Convention on Wetlands similarly emphasizes that wetlands must be managed as ecological networks rather than isolated protected areas.

Kashmir provides an excellent example of this principle.

Hokersar, a designated Ramsar Site, is recognised as the Valley’s premier wintering wetland and has supported hundreds of thousands of waterbirds during favourable years. Wular Lake, another Ramsar site and one of Asia’s largest freshwater lakes, performs complementary ecological functions, supporting different bird communities depending on water depth, food availability and seasonal conditions. Haigam, Shallabugh, Mirgund, Chatlam Wetland Reserve, Fashkoori Wetland Reserve, Manibugh Wetland Reserve, and Krenchoo Wetland Reserve provide additional feeding and resting habitats that reduce pressure on the larger wetlands.
These wetlands are not competitors. They are ecological partners. If Shallabugh loses its shallow feeding areas because of drainage or pollution, birds shift to Hokersar or Haigam. If Wular experiences excessive siltation or invasion by willow plantations, species dependent on open water are displaced elsewhere. Such displacement creates overcrowding, intensifies competition for food and increases the risk of disease transmission. In ecological terms, this creates a cascading effect throughout the wetland network.

Climate change is making this challenge even greater. Altered snowfall patterns, erratic precipitation, prolonged dry spells and changing river flows are modifying the hydrology of Kashmir’s wetlands. Scientific studies indicate that Himalayan wetlands are becoming increasingly vulnerable to reduced water availability and habitat fragmentation. When these pressures combine with human-induced threats such as encroachment, untreated sewage, agricultural runoff, indiscriminate weed growth and unregulated development, the ecological resilience of the entire wetland system declines. Yet the significance of these wetlands extends far beyond migratory birds.
Healthy wetlands regulate floods by storing excess water during periods of heavy rainfall. They recharge groundwater, improve water quality by filtering pollutants, trap sediments, store carbon, support fisheries and sustain local livelihoods. In the context of increasing climate variability and extreme weather events, wetland conservation is therefore an investment in both biodiversity and human well-being.
For Kashmir, conservation must move beyond site-specific management towards a landscape – level approach. Restoration should focus on maintaining natural hydrological connectivity among wetlands, reducing pollution, controlling invasive vegetation, preventing encroachment and ensuring adequate environmental flows. Regular scientific monitoring of bird populations, water quality and habitat conditions should guide management decisions. Equally important is greater public awareness that wetlands are living ecosystems providing essential services to society.

India has already committed itself to the Central Asian Flyway Action Plan and the objectives of the Ramsar Convention. Kashmir, because of its unique geographical location, has an opportunity to become a model for flyway conservation by managing its wetlands as one integrated ecological system.

The annual arrival of migratory birds is not simply a symbol of nature’s beauty. It is an indicator of the health of our environment. If one wetland deteriorates, the effects are felt far beyond its boundaries, extending across the entire flyway and ultimately influencing bird populations across continents.

The message from science is clear – every wetland matters. Protecting Hokersar alone is not enough. Conserving Wular alone is not enough. The future of migratory birds and the ecological security of Kashmir itself depends on safeguarding the entire network of wetlands that together sustain one of the world’s greatest migratory journeys.
