if 10,000 is allowed and we get 10,000
the natural increase in your above eg is 2500-3000 without predation...so we could keep numbers at 10,000 by allowing them to roll over population every 10 years so need 1,000 replacements bred (and left to live)each year so need to shoot 1500-2000

3000 was a number I made up to make an example that I then didn't bother with posting. It has no bearing on anything. I believe the number specified for the required yearly harvest to keep numbers stable at 10000 in the Tahr control plan is 1900 but that's from memory. There are inherent difficulties and large error bars to any of these data though because wild animals in a wild landscape do not neatly fit into formulae

The long and short of it is that good ongoing monitoring is required to understand the trends in tahr population if it's to be effectively managed
