The Delhi Zoo authorities have implemented several measures as part of their winter management plan to protect animals from pollution and cold weather. These steps include water sprinkling to control dust, replacing firewood with stubble padding, and using eco-friendly vehicles.
Zoo officials have outlined proactive measures to minimise both the direct and indirect effects of pollution as air quality in the national capital continues to decline in December. While the zoo’s location in a relatively lower-lying area provides some natural protection, safeguarding the animals remains a priority.
According to an official, “Pollution levels here are relatively lower due to the zoo’s geography, but we are still taking various steps to protect the animals”.
To combat local pollution sources, the zoo has reduced the use of diesel vehicles, replacing them with cleaner, eco-friendly alternatives. “We have already reduced the number of high-polluting vehicles and switched to cleaner, mini diesel-free options,” the official said.
Water sprinkling is regularly conducted, particularly near the ring road and other areas affected by external pollutants. Fogger machines are being used to spray water and further reduce dust and airborne pollutants.
As part of long-term measures, the zoo has planted numerous trees to maintain a clean and green environment. These green initiatives, along with other efforts, help improve air quality on the premises.
Dust control has been incorporated into the zoo’s daily cleaning routines. “Before sweeping roads or animal enclosures, we sprinkle water to prevent dust from rising. Zookeepers have been instructed to avoid unnecessary activities that could increase pollution,” the official explained.
On the morning of December 17, the air quality in the capital was in the ‘severe’ category, with an AQI of 427, and the temperature was 5.9 degrees Celsius, two degrees below normal.
To keep animals warm during the cold winter, the zoo has updated its practices. In the past, wood was burned during winter nights to provide heat, contributing to pollution. This year, the zoo has completely stopped burning wood and switched to non-polluting alternatives, such as heaters. For herbivores, special bedding arrangements have been made in enclosures to ensure warmth.

An innovative approach involves using stubble, which is typically associated with pollution due to burning, as bedding for animals. “We purchase stubble during this season and use it as padding in animal enclosures. This not only provides warmth to the animals but also helps manage stubble in an eco-friendly way,” the official added.
Additionally, winter is an ideal season for breeding, and the zoo is taking steps to support this. From monitoring food to regular health check-ups, every effort is being made to ensure the well-being of both newborn animals and their mothers during this period.
The National Zoological Park, also known as the Delhi Zoo, covers 176 acres and is managed by the central government. It was established in 1952.
