later estrous cycles will have fawns at a time when habitat conditions<br />

are at their poorest. As a result, later born fawns often have lower<br />

weights and poorer antler development than their earlier born cohorts.<br />

It may take several years for late born fawns to catch up with respect to<br />

physical condition.<br />

<strong>In</strong> populations heavily skewed toward females, population density<br />

often is excessive and out of balance with existing habitat conditions.<br />

Attempts to control<br />

overall herd density<br />

through harvest becomes<br />

increasingly<br />

difficult as sex ratio<br />

becomes<br />

more<br />

skewed toward females.<br />

Does have<br />

different habitat requirements<br />

and<br />

preferences than do<br />

Excessive deer numbers and few antlered bucks<br />

often are problems associated with deer<br />

populations heavily skewed toward female deer.<br />

bucks outside the<br />

breeding season.<br />

Poor growth rates<br />

among younger deer<br />

and poor reproductive success for does generally are associated with<br />

increased competition for food and cover. These negative impacts are<br />

typically the result of too many does, rather than too many bucks (Miller<br />

et al. 1995).<br />

<strong>In</strong> herds with doe-heavy sex ratios, bucks have to do very little<br />
