This is how South Georgia got rid of its rats to preserve its birds, a lesson India can learn from

South Georgia which was known as the world's largest island of poisonous rats for the first time in 200 years has declared the island rat-free. 

Eradicating rats from over 1087 sq km (108,723 hectares) was a big challenge but they took up this project and planned three phases (2010-2011), (2012-2013) and (2014-2015).

This massive arduous job cost them more than $13 million. Nearly 300 metric tons of poison rats were thrown out of the island using helicopters.

Georgia government deployed three rodent detection dogs who went sniffing nearly 2420km, more than 4,600 rat chewsticks and rat-tracking tunnels were used to accomplish the task.

April this year a team of 16 people were sent to find out if the rats have been eradicated. The team took thousands of wooden stakes coated with peanut butter and some trained sniffing dogs but they found that there was no rodent left and hence declared the island rat-free.

Georgia was once known for beautiful pipit bird but over the years because of the rodent rats, there was only one pipit that was seen. But now since there are no poisonous rats in Georgia, pipits have already responded as they feel their eggs and chicks can be safe.

Another breed of duck called pintail disappeared after the rodent rats increased in number on the island. But now since rodent eradication project is complete there is a possibility that the pintail can return to their home.
