It looks like someone came in with a pair of scissors and cut each stalk then trampled them down. The same thing happened to the daffodils I had planted near them. I've had them for many years and this has never happened before. Any idea what animal might have done this?

My best guess is that this is cutworms. More information on these pests can be found here:
Barring that, it could be deer but it depends - were any of the plants actually eaten outside of being bit off at the base?
