You are right that there are many other variables that I could have included in my example ,but that would have made it a lot more complicated and harder to understand. Even, the fact that I used net recruitment instead of the total number of fawns introduced into the fall herd , made it more confusing. I said the net fawn recruitment was ten, but accounting for 10%non-hunting mortality of adult deer, that means there were actually 12 fawns introduced into the fall herd.

So ,to keep the herd stable, one still has to harvest 10 deer, but it changes the age distribution of the harvest required.
