How to Use This Calculator
- Enter the current population size and number of breeding pairs.
- Set offspring per pair per year and juvenile survival rate.
- Input adult annual survival rate, generation time, and recovery target population.
- Review the recovery outlook rating and estimated years to reach the target population.
- Use the annual growth rate to assess whether current management is sufficient.
