It seems to me that one of the better tactics for deer number management is removing the older 'mature' does that are more likely to produce and raise twin fawns. You know the ones I'm talking about? What we call 'long heads' (MO even has a question on the 'tele-check' system asking about length of head) that seem to know all the tricks and snort like a steam calliope when they catch a hint of human scent.
