卑诗Prince George的Forests for the World公园在Shane Lake西北岸建成一座八米长步桥，让行人跨过蝾螈、蟾蜍和青蛙幼体的迁徙通道。工程11月12日完成，目的是减少每年7至8月动物从湖边进入树林时被踩踏。
当地林业工作者Ashley Sutherland于2022年注意到问题后联系市府，先推动设置提醒牌，之后与市府、Nahanni Construction及其他伙伴合作建桥。她称2025年环湖主要步道观察到的死亡率最高达12.8%，但并非所有死亡都是踩踏造成。
报道未取得总工程造价。承建方称市府承担约三成，其余来自捐助；市府公园部门表示正在计划约100米外的第二座桥。新设施可降低一种风险，但不能据此断言当地两栖动物数量已经恢复。
