Grizzly Bear Quota
The diagram below shows how the grizzly bear quota for outfitters is calculated.
| Steps |
Example |
| 1. Estimate
male and female population size in management area |
15000 km2
outfitter area
X
density estimate (mean of 3 independent estimates for each of 22
ecoregions) |
| 2. Review population
estimate, uncertainties, and bear population biology with outfitters |
estimated 200
bears |
| 3. Calculate
maximum sustainable yield @ 2 per 100 females and 6 per 100 males |
female potential
yield = 2 |
male potential
yield = 6 |
| 4. Subtract
expected annual resident and defense of property kills (estimated
from previous kill trends) |
-0.8 |
-1.5 |
| 5. Allocate
remainder to outfitters |
1.2 |
4.5 |
| 6. Multiply
by point values |
1.2 x 3 = 3.6 |
4.5 x 1 = 4.5 |
| 7. Add to annual
yield points |
8.1 |
| 8. Multiply
by 3 years |
8.1 x 3 = 24.3
(rounded to 24) |
