Sanctuary's Thirst: Water tankers rush to save wildlife
16 Sep
Summary
- Thousands of liters of water are delivered daily by tankers.
- Feral horses consume the largest share of water at 40 liters daily.
- Migratory bird numbers have significantly decreased due to drought.
Nagapattinam district's Point Calimere Wildlife and Bird Sanctuary is experiencing a severe water shortage, with daily deliveries of thousands of liters by water tankers to sustain its animal population. The region has not seen rainfall since February, and soaring temperatures exacerbated by El Nino have caused vital wetlands to dry up. This critical situation necessitates the constant replenishment of water troughs for numerous species, including blackbucks, spotted deer, jackals, and bonnet macaques.
The sanctuary's feral horse population, while not native, are significant water consumers, with each adult requiring approximately 40 liters daily. Forest officials are implementing measures such as using plastic saucer-type tanks and pumping water from dwindling bore wells. However, maintaining the water supply proves challenging due to rapid evaporation and contamination from animal waste.
The drought's impact extends to the sanctuary's renowned avian population, with a marked decrease in migratory birds observed. Key water bodies like Muniyappan lake have dried completely. As a result, animals, particularly spotted deer and feral horses, are venturing into nearby villages in search of water, posing risks of accidents and encounters with stray dogs. Authorities have increased patrols to monitor these animals.
Wildlife biologists note that migratory bird numbers are expected to rebound only after the monsoon season begins. The lack of water also affects the broader ecosystem, with the drying up of swamps, mudflats, and salt marshes. The department is actively working to mitigate the immediate crisis, but a return to normalcy hinges on adequate rainfall.
