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

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