Modelled kill rate estimates (95% CI) for different treatments. Salt = cut and paint salt solution, Dig = manual uprooting, Stub = cut and paint glyphosate, Leaf = glyphosate leaf treatment. For ease of comparison we plotted the average predictions across all dune areas for the median amount of stems (10) and the mean log(volume) (5.2). Significant differences between treatments were tested with a post-hoc Tukey test. Treatments with the same letters above are not significantly different (p < 0.05).
