The overall mean weighted effect size was 0.75 (95% CI: 0.50, 1.00), corresponding to a roughly 40% overall decrease in road-kill between impact and controls (Fig 3).
Contexto
What changed: Implementation of road mitigation infrastructure such as fences, wildlife crossings, reflectors, and detection systems. Comparison: Control locations without mitigation or pre-installation baseline periods. Limits: High heterogeneity across interventions, geographic concentration in North America, and evidence of publication bias in journal articles.
