Summary plot of all effect size estimates from evaluations of the effectiveness of spawning habitat creation or enhancement on fish abundance (k = 39) subgrouped by intervention categories. Intervention type code definitions can be found in Table 3. Error bars indicate 95% confidence intervals. A positive mean value (right of dashed zero line) indicates that the abundance was higher in treatment areas than in control areas (no intervention). Waterbody mods: waterbody modifications.
