Coefficients show the difference in introduced provenance (New Zealand) plants compared to native provenance (United Kingdom) plants. P-values are calculated from a Wald chi-squared test with one degree of freedom for the fixed effect of provenance. Statistically significant P-values are highlighted in bold.
