RE: Buck/Doe Ratios
When yearling males disperse from the herd usually establish larger home ranges than when they were with their mothers. The dispersal of your younger buck benefits in less " incestuous" activity. doe disperal does not carry as large of a benefit. Does will usually suffer a higher fawn mortality because of possibly unfamiliar ground or they might have to partake of lesser quality habitat.
Dipersal is natures way of filling every available " niche" .
