deer damage

Hello! So we have a little dwarf spruce we planted last summer only about 3’ tall and over the winter a deer completely ate out the middle of it. I’ve been watching to see if it comes back this spring - apparently the top half is completely dead, but the bottom 12 - 18 inches is alive with new...

Had hoped this tree would develop. Can you tell me if it is lost or what, if anything, should be done to save it?
