Notes

  • T7095 - The short-term trend is statistically uncertain but with a growth rate of 1.0013 (SE 0.1023) indicating a stable/fluctuating population. In the long-term, the population has almost doubled since the 1980s although TRIM has assessed the long-term trend as stable. López Gómez et al. (2017) reported redistribution of the population in ZA.
