I had an amazing trip to the Southern Hemisphere, South Georgia and Falkland Islands. There were some superb photographers on this trip, and I learned much.
So. Georgia was devastated by whale and seal hunters in the early 1900s. The ships brought rats which greatly diminished the bird populations.
In the last 20 yrs they have poisoned the rats without poisoning the other species, and it has been a successful environmental restoration. South Georgia and the Falklands have incredible biodiversity with hundreds of bird and mammal species.
I wonder what would be restored in our society if we eliminated the King Rat.
No one lives in South Georgia, so all the money for restoration has come from elsewhere. Please enjoy attached images.
