The football club said the project would take place over several years, with consultation promised for local residents.
It stressed that the vision was to “significantly increase opportunities for people of all ages and backgrounds to be active”.
Wycombe Wanderers said it was committed to working with existing users of the playing fields and golf course and it had already met with a number of local organisations this summer.
However, Stoke Poges Task Force said the announcement wrongly implied that meaningful talks with the community had taken place.
It argued that consent had not been established for the project’s direction, according to the Local Democracy Reporting Service.
The task force questioned the benefits of a smaller nine or 12-hole course – and argued there was little evidence of demand for such a model.
A spokesperson said: “This is not just a Stoke Poges issue. Far from it.
“If development of this green belt land is allowed to proceed, it sets a precedent that threatens the protection of our green belt across Buckinghamshire and beyond.”
