What's eating my sapling and will it survive?

[spandit]

The wild cherries were the first to leaf and most of them are looking good still but this one has been attacked by something and is looking the worse for wear.

 

Is it likely to die or will it just come back stronger next year?

 

[Goaty]

If it gets what it needs in sunshine, water etc, It should grow again this year.

Deer? Too much water? Buried roots? Chemicals leached from treated wood?

 

I don't knwo. Obviously!
