At an inquest into Sophie's death held in Huntingdon in December, coroner David Morris recorded a narrative verdict.
The inquest heard the tree was examined prior to the incident and if recommendations had been implemented, the tree would have been made smaller, greatly reducing the risk.
It was found 11 trees in Middletons Road recreation ground were found to be a "high risk" hazard that required immediate removal and a further 18 were found with defects also requiring immediate treatment.
"Sophie's parents are still struggling to come to terms with the fact that their daughter would still be here today if these checks had been carried out."
