Summary of vote counting by vegetation types, only if change in vegetation type in response to Tamarix control effort was reported as statistically significant by the published source. Each cell represents a combination of invasive classification (desirable/undesirable/total) and growth habit (overstorey/understorey/both). Bars represent the numbers of desirable outcomes (shown in blue), undesirable outcomes (red), neutral outcomes (dark grey) and no-change (light grey). Widths reflect sample size, with number of observations (number of papers in parentheses) reported in each cell. Note that “overstorey” and “understorey” sample sizes do not add up to “overstorey + understorey” sample sizes, as response variables were not always reported as specific overstorey/understorey metrics.
