POPULATION OF ROCKY MOUNTAIN BIGHORN SHEEP IN THE WHEELER PEAK WILDERNESS, NEW MEXICO
FIGURE 3.12 The population grew exponentially at a fixed rate of 28% per year, from 32 to 180 individuals in seven years (numbers rounded to nearest individual); the population growth shown from 180 to 4,460 sheep is potential growth, assuming a continued constant rate of exponential growth. Growing exponentially, this population would increase by nearly 140 times in 20 years. (Data from Rominger et al. 2004)
