They were abducted by aliens.
Anyway, I don't really see the problem. If you don't have any "classic" trees you can easily build your own cutom ones, or buy some off PaB or Bricklink. There are loads of ways to make custom trees (this is probably something I would do in any case, though I haven't ever needed to use trees in any of my brickfilms thus far...). Besides, with custom trees, you can easily vary the size, shape, and colour of the leaves (especially with the new dark red and olive green leaf elements), which you could never do with the pre-moulded trees. And frankly, this is far from being at the top of my LEGO-related problems list...
