Simple answer is to farm Rhino commercially, for their horn, and flood the market to the point that going out and shooting one of the bad tempered buggers becomes a non-starter from a commercial point of view.
If you can get 30g of premium Rhino horn on eBay for £20 you are not going to buy some in a landrover under cover of darkness.
I think that seeing Rhino charging around in the fields of England would be a nice side benefit also.
