Just a thought, 20,000 acres is a huge area, Thats like 31 square miles at that point it is not a canned hunt. That is an area more than five miles by six miles. YOu can hunt for days an never see the animal you are after.
There's more to it than just the size of the land.
The major questions about fenced areas is how long has the animal been there and how habituated to people & vehicles is it?
If it's only been there a day or two then it doesn't know the area and escape routes etc so even if no drugs are clouding the animal's mind, the hunter still has an advantage over a normal hunt and that just ain't right.
You might say what if the animal has been in the area for a considerable time? and the answer to that is it's highly unlikely. Let's first do some sums and work on just one lion eating one impala valued at US$100 per day.
If the animal is there for just 10 days, that's $1000 out of the potential profit or $3000 if it's there for just a month.
Then factor in that lions don't know the difference between an impala, a kudu or a sable etc and just an occasional kill like that can quickly cost the landowner thousands more.
If more than one lion on the property, costs can escalate incredibly quickly so it's in the landowners interests to have the animal on his property for as short a time as possible.
Now factor in the fact this animal is habituated and very possibly more likely to run towards a vehicle than away from it and you quickly realise that a pen bred and released lion has about as much in common with a true wild lion hunt as chalk and cheese.
I haven't even begun to address the issue of drugged animals here but if I did, you'd very quickly realise what a abomination that is as well.
I personally believe that these canned shoots and the fidiots who put them on you tube etc will be the death of all African sport hunting and the more & sooner we disassociate ourselves from these shameful practices the better.
