Campaigners have rallied together to express their concerns to WBC.
The page said: "Please let Wokingham Council know that this is a total misrepresentation of the community's feeling towards this beloved Green Space - a location which has been a lifeline during the pandemic."
It added: "Let them know that we want this area of land preserved as Green Space and DO NOT want to see it earmarked for a future development like the MRT - a scheme which Wokingham Council rejected after unprecedented levels of opposition."
The concerns follow a consultation in spring last year in which the public was invited to nominate local green spaces for protection.
