Deer-proof Hedging

I have just bought a bit of a field,and I want to put a hedge around it and make a garden. The only problems are 1. Deer from the neighbouring forest potter about in the field & munch everything (except holly apparently), 2. the soil seems to be pure clay. I don't want any more holly, so does anyone have any informed ideas about what would be suitable hedging plants to choose? Not leylandii!

 

Yew is apparently poisonous to grazing animals, but I presume you do not want to kill the deer. However I do wonder if the deer would perhaps avoid this. Most wild animals tend to reconise such dangers, but I am not sure about this, it is just a thought.

 

In my experience, while living on the edge of Exmoor, such a thing as a "deer proof" hedge, particularly in the short term, was about as rare as finding hen's teeth. You might have to opt for fencing I'm afraid, or a combination of hedge and fence, if you really want to keep them out. Sorry it's a negative reply.

 

Thanks for all these ideas. I'm sorry that I didn't make my problem quite clear...My garden borders Epping forest, and I don't really mind if the deer get in, they are very nice to look at, but I want a hedge for privacy. The hedge is also to keep the toddlers from straying into the forest. I want plants that the deer won't eat, especially while they're getting established. I suppose that realistically, the kids will be fully-grown before the hedge!
