In 2012 there was a row over proposals to cull 200 Canada Geese on Windermere.
It was postponed and now the two sides are working together on a plan to manage the problem.
The RSPCA, who were opposed to killing the birds, and rangers from the national park have joined forces.
Hundreds of the geese have now been ringed in an attempt to track their movements, as Samantha Parker reports:
A joint operation between the RSPCA and the Windermere Geese Management Group is being carried out to help understand and track geese in the area.
By ringing a number of birds, experts and wildlife officers are hoping to monitor where the geese come from and why.

"We are doing this to better understand where the geese come from and why.
"We may find that some of the geese are resident in Windermere all year round and that others are just visiting. The answers will help to inform the management of them in future.
"How it works is you ring a number of birds, using highly visible rings, over a number of years and wait for them to be seen and reported."
