I want to know the answer to the following question:
In 2001, what organization conducted a survey of residents regarding London's fox population?
All the background I'm provided with is that "A survey in 2001 by the London-based Mammal Society found that 80 percent of 3,779 respondents who volunteered to keep a diary of garden mammal visits liked having them around.". Is that enough to answer the question?
Answer: yes
