I Don't Get It

Saw this sign last night...bit confusing, non?

So don't cut down the trees? 

But that is a gun is it not?

So don't shoot the hidden birdies in the trees?

Or maybe hidden unicorns?

Again, I am confused.

Sigh*

Only in Wakefield, Quebec.

p.s. It looked like someone had tried shooting the SIGN!

YIKES
