The point really is that a male may be breed with 20 females...so using your stats, cutting off his 00’s would be even more successful in cutting down the population.
That 6 month old buck fawn will also breed the does.
The bottom line is that it is next to impossible to control a wild deer population with birth control methods.
A buck will travel for miles in search of hot does, and a park full of hot does would attract a bunch of them!
