Appendix Table 4.

Life table based on the mortality rates of planting cohort monitoring studies.

The worse-than-normal survivorship column uses the 75th percentile annual mortality rates, the middle-of-the-road survivorship column uses the 50th percentile values, and the better-than-normal survivorship column uses the 25th percentile values. When studies provided a range for the time period, we used the lower value and higher values of time to calculate the lower and higher mortality rates, respectively. The first five years used establishment mortality rates, while years 6+ used post-establishment rates. Approximate population half-lives are bolded.
