Otherwise, if the population size trend indicates a nonzero number of individuals when extrapolated to the present (Example 2), then the population should be considered extant.

       * Population visited and known as extant within the past 20 years: likely consider extant
       * Population not visited in more than 20 years: possibly consider extinct
       * Population not visited in more than 40 years: likely consider extinct. (In the example above, the population would be considered extinct.)
