  1. #19 Bobcat Season Setting Process

  2. NDOW Approach  Production  Adult Male - Adult Female Ratio  Effort - Harvest HOW IT WORKS

  3. Production  Production has greatest single influence on population growth.  Intuitively, populations follow production trends up and down.

  4. What Influences Production? 16.00 14.00 12.00 10.00 Precipitation 8.00 6.00 4.00 2.00 0.00 0 20 40 60 80 100 120 Kittens per 100 females

  5. Adult Male - Adult Female Ratio  This ratio can indicate over-utilization.  Males are more susceptible to capture (larger home range)

  6. Adult Male - Adult Female Ratio  In a healthy population males will be less numerous than females. (higher morality rate)  Male/female harvest ratio approaching 1:1 indicates population is in decline and being over utilized.
