Table 2. Associations between effect sizes and (A) mitigation category (n = 39); (B) road type (n = 19), for the subset of studies involving large mammal fencing.
Mitigation category: Crossing structures with associated fencing, animal detection systems, and wildlife reflectors; Road type: ≥4- lane divided highways, and 1–2 lane roads. Notes: Null model = random-effects model.
