Protecting some young saplings

I've recently planted out three saplings - two oak, one alder. The two oaks were grown from two acorns which I found locally and the alder was found growing on my lawn (I think).

Each are about 15 inches high

I get rabbits on my land so am wary of them going for the saplings - what is the best way to protect them? I've thought of those spiral tree guards but they are too big and wide for such small saplings.

Thanks

 

A tube / roll of chicken wire dug in around each sapling, with an open top and enough room around the saplings for them to expand? It will need to be dug into the earth though, rabbits can dig down and under wire fences!

 

Thanks, sounds like a good idea. But how deep to bury the wire?
