My opinion and this will be the only time I will give regardless of how a tree fares if his tree was a redbud a redbud should be planted , a tender white won't do much better then a redbud anyway , that park is full of different tree types that have survived , maybe they would allow a split rail or a nice small area protecting both the tree and plaque , I highly doubt even the worst kid will damage a memorial tree or plaque , but there are always exceptions to the norm I guess
