Deer reproduction and fawn survival factors

The life cycle and survival of deer depend on specific biological and environmental factors. A deer's gestation period typically lasts between 6.5 and 7 months, with conception often occurring in the fall or early winter. This timing ensures that fawns are generally born in late spring or early summer, coinciding with more abundant food resources and milder weather.

Fawn survival rates vary significantly, typically ranging from 30% to 70% during their first year. Key factors influencing these rates include predation from animals such as coyotes, wolves, and bears, as well as habitat quality, nutrition, and weather conditions. During their first few weeks, fawns are particularly vulnerable and rely on natural camouflage and maternal care for protection.
