POPULATION GROWTH POTENTIAL
Deer have the ability to reproduce and expand their numbers at an almost exponential rate. A classic example of deer herd growth potential is documented at the George Reserve in southern Michigan.This area is a 1,200-acre tract enclosed by an eleven-foot deer-proof fence. In 1928, six deer (2 bucks and 4 does) were released inside the area. Six years later, a drive count yielded a minimum population of 160 deer (Hickie 1937). The growth of the George Reserve herd reflects a mathematical model known as the logistical equation (Caughley 1977).
This model is characterized by an S-shaped curve reflecting how factors such as reproductive success and mortality affect a population. During the early stages of population growth, deer numbers are low and quality forage is abundant. Consequently, mortality is low and reproductive output is high. As the population increases, so does competition for quality forage and other habitat components. This increased competition leads to lower reproductive output and fawn survival. The fawn recruitment rate eventually reaches a point where it equals the mortality rate and the population stops growing. Physical condition of the herd is usually poor and disease problems may be chronic. A deer herd at this point has reached absolute carrying capacity or CC K.
