CritterCross is a community-powered platform that maps wildlife-vehicle collisions across the U.S. — turning everyday sightings into data that protects animals and saves lives.
Free app. No spam. Unsubscribe anytime.
Wildlife-vehicle collisions happen millions of times a year across the U.S. CritterCross turns drivers into the first line of defense — mapping where animals and roads meet so we can make both safer.
See an animal on or near the road? Pull over safely and open CritterCross. Your location and time are captured automatically.
Take a photo and our AI — powered by iNaturalist — identifies the species instantly. Or search our full U.S. wildlife database.
Submit your report in seconds. It joins a national map that wildlife agencies and transportation departments use to take action.
Wildlife doesn't have a map. But we do. CritterCross turns citizen observations into actionable intelligence — pinpointing the corridors where animals are struggling to cross our roads.
That data flows directly to state wildlife agencies, departments of transportation, and conservation organizations working to build safer crossings, better fencing, and smarter road design.
Every report you submit is a data point. Together, they build a picture no single agency could create alone.
No wildlife expertise required. CritterCross makes it easy for any driver to contribute meaningful data.
Snap a photo and species identification is handled automatically via the iNaturalist API — covering 70,000+ North American taxa.
GPS, date, and time are auto-filled. A report takes under 30 seconds from open to submit.
Explore collision data by state, species, and season. Share findings with your community.
CritterCross is in active development. Here's what we're building toward as our community and dataset grow.
A live, public map of collision density across the U.S. — built from community reports and designed to show the corridors where wildlife and roads most dangerously meet.
Time-aware notifications that warn drivers when approaching a high-risk corridor at dawn or dusk — the windows when collisions spike.
As the dataset matures, CritterCross aims to share data directly with state DOTs and wildlife agencies to inform infrastructure and signage decisions.
Join the waitlist and help build a safer country for wildlife and drivers alike.
