#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
When a highway became a deadly barrier to evolution itself, engineers built an invisible detour that wild animals instinctively learned to use.
By Brendan Brown
Published September 6, 2026"The #TransCanadaHighway runs straight through #BanffNationalPark — 82 kilometers of four-lane road through the Canadian Rockies, carrying a vehicle every few seconds through some of the richest wildlife country on the continent.
"For decades, the arithmetic of that arrangement was written in carcasses. The highway killed elk, deer, bears and wolves at a relentless rate, and did something quieter and worse besides: it cut the park’s animal populations in two, a river of traffic no prudent animal would cross, splitting gene pools on either side of the pavement.
"Canada’s answer, built out over three decades, was to give the animals their own infrastructure — and it has become the most-studied, most-copied piece of #wildlife engineering on Earth.
Six bridges, thirty-eight tunnels
"Along that one stretch of highway, Parks Canada built 44 crossing structures — six overpasses and 38 underpasses — beginning with the first two overpasses in 1996 at about $1.5 million each.
"The overpasses are the famous ones: to a driver they look like ordinary concrete bridges, until you glimpse the top and see forest running unbroken across them — trees, shrubs and grass planted fifty meters wide, a strip of the Rockies carried over four lanes of traffic. The underpasses do the volume work below: culverts and tunnels sized for everything from cougars to moose."

#Ecology101 - #Wildlife corridors
By admin - December 17, 2025 608
"In an increasingly human-dominated world, the natural landscapes that once stretched unbroken for miles are now often fragmented, carved up by roads, cities, and agricultural fields. This #fragmentation creates isolated 'islands' of habitat, trapping wildlife populations and threatening their long-term survival. Imagine a vibrant ecosystem, bustling with diverse life, suddenly cut into pieces. This is the challenge that wildlife corridors seek to address, offering a lifeline to nature by re-stitching the fabric of our planet.
The Urgent Need for Connectivity
Habitat fragmentation is a silent crisis, severing the vital connections that allow species to thrive. When large natural areas are broken into smaller, isolated patches, animals find themselves confined. This confinement leads to several critical problems:
- Limited Resources: Smaller areas mean fewer food sources, less water, and reduced shelter, especially during seasonal changes.
- Increased Vulnerability: Isolated populations are more susceptible to local extinction from disease, natural disasters, or even random events. A single wildfire or severe storm could wipe out an entire population.
- Genetic Isolation: Perhaps the most insidious threat is the loss of genetic diversity. Without the ability to move and breed with individuals from other populations, species become inbred, weakening their resilience to environmental changes and diseases.Wildlife corridors emerge as a powerful solution to these challenges. They are essentially pathways of habitat that connect otherwise isolated natural areas, allowing animals to move safely between them. These connections are crucial for maintaining healthy, robust ecosystems."
