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 by 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.
Search for the species by name, or pick from the species you and the community report most often.
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.
Search iNaturalist's database of 70,000+ North American taxa by common name, or tap one of your most-reported species.
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.
These features are planned for a future version of CritterCross. They are not in the app yet.
Snap a photo and the species is identified automatically using iNaturalist's computer vision.
Time-aware notifications that warn drivers when approaching a high-risk corridor at dawn or dusk, when collisions spike.
CritterCross is in active development. Here's what we're building toward as our community and dataset grow.
A public map of statistically tested collision hotspots across the U.S., built from community reports once there is enough data, to show the corridors where wildlife and roads most dangerously meet. Today the app map shows report clusters: groups of reports within 1 km of each other.
As the dataset matures, CritterCross aims to work with universities, state DOTs and wildlife agencies, and conservation nonprofits, sharing data to support research and to inform wildlife crossing, infrastructure, and signage decisions.
Join the waitlist and help build a safer country for wildlife and drivers alike.
