Canada built 44 wildlife-crossing bridges and tunnels

via Bob 🇨🇦🇲🇽🇺🇦 (@bielsubob@infosec.exchange): Canada built 44 bridges and tunnels across a single stretch of highway so that animals could cross without dying, and collisions with wildlife there have fallen by more than 80%, with grizzly mothers now teaching their cubs to use the crossings like a route the family has always known

Banff National Park’s 44 wildlife crossings — six vegetated overpasses and 38 underpasses, paired with fencing along the Trans-Canada Highway — have cut wildlife-vehicle collisions by more than 80% (96% for elk and deer). What I find most interesting is the multi-decade feedback loop: 250,000+ camera-logged crossings show animals learning the routes and passing that knowledge to their offspring, so the infrastructure gets more effective over time.
