Q.How can I save my dwarf Mango tree
Dwarf Mango tree has been shredded by possums. It is only about 8 ft tall. Can the trunk of the tree be repaired or should I cut it back below where all the bark has been removed?
I would appreciate your advice.
Thank you.

As long as this tree has some segment of bark connecting the bottom half to the top, then it will likely recover.

Fencing will be the best option to protect your trees. Otherwise, you can try using predator urine near your trees, as this will keep them away as well.
