the CWGC cant help you with this,they have no power in these matters,they are only responsible for making sure that the soldiers grave is properly marked and the headstone they erect is properly maintained,they have no say when it comes to the grave itself,because its a private grave,only graves in CWGC cemeteries are their resposibility,when a burial ground becomes redundant,the CWGC make arrangements to remove the headstone and have the soldier commemorated elsewhere,usually at the nearest cemetery.
the only surefire way that this graveyard could have been saved,is if the CWGC had left the headstone where it was,because NOBODY can touch a grave thats in the care of the CWGC
