Environmental decision support
Build for people.
Protect wildlife.
See real wildlife, habitat, and infrastructure data for any Long Island location, free. Planning a specific project? Screen it against that same data before you build.
Report WildlifePeople and wildlife share the same land. They rarely share the same information.
Roads, buildings, and parking lots can cut through habitat animals depend on. The data that would help anyone (a resident, a planner, a project team) see that early is real and often public, but it isn't organized in a way that's easy to use.
Wildlife data is scattered
Sightings, roadkill reports, habitat maps, and infrastructure plans usually live in different systems that don't talk to each other.
People and wildlife get planned separately
Communities, agencies, and project teams often make land-use decisions without an easy way to see how wildlife uses the same land.
By the time it's visible, it's expensive
Once a design is finalized or construction has started, addressing a wildlife or habitat conflict can be far harder and costlier.
One picture of an area. Two ways to use it.
Coexist Explore is free for anyone who wants to understand an area. Coexist Analyze applies that same real data to a specific project.
Coexist Explore
See what's really happening in an area, no account needed.
- Real wildlife sightings and roadkill reports near any location
- Habitat context: wetlands, forests, and protected land
- Road and infrastructure conflict signals
- Search any address, town, road, or park on Long Island
Coexist Analyze
Screen a specific proposed project against that same real data.
- Apply the same real data to your specific proposed project
- Helps identify potential wildlife and habitat concerns early
- Compare project locations or design alternatives
- A shareable summary for teams, officials, and reviewers
Project Analysis
A clearer way to understand how development may affect wildlife.

Potential actions
- Preserve the existing tree corridor
- Evaluate an alternative alignment
- Reduce disturbance near habitat edges
- Review wildlife-sensitive crossing options
From environmental data to better decisions.
Traditional workflow
- Separate datasets
- Multiple portals
- Manual interpretation
- Concerns discovered late
- Difficult communication
Coexist approach
- Environmental context in one workflow
- Wildlife-focused project screening
- Clear priority concerns
- Evidence and confidence indicators
- Possible actions for expert review
We built Coexist to work alongside professional expertise and your existing GIS tools, not replace them.
How real data turns into a better decision
Step 1
Search a location or project site
Step 2
See real wildlife, habitat & infrastructure data
Step 3
Understand the area, or screen your project
Step 4
Make a more informed decision
One Better Decision. Two Kinds of Impact.
Coexist starts with wildlife: understanding habitat, and where it intersects with roads and development, is what makes a better-informed decision possible for animals and for the people planning around them.
Economic & human value
- Can help reduce costly redesigns or delays from conflicts discovered late
- Supports environmental review and permitting conversations with real data
- Gives communities and officials clearer, shareable information
- Can inform more efficient project planning from the start
Environmental & wildlife value
- Helps identify habitat and wildlife movement areas before construction
- Supports efforts to reduce wildlife-vehicle collision risk
- Helps surface nearby wetlands, forests, and connected habitat
- Can inform climate-adaptive planning decisions
Better-sited, wildlife-conscious development may also be a secondary lever for climate resilience. That isn't Coexist's primary focus, but it can be a possible additional benefit.
Designed for decisions that shape the landscape.
Long Island Coverage
Built for all of Long Island.
Coexist is built to cover every town across Long Island, not just one. Our first real dataset comes from Port Washington, NY, and shows what happens when wildlife observations, habitat data, infrastructure, and local knowledge finally sit in one place.
View the mapBase map geography, community-submitted observations, restoration and infrastructure project records, wetland and forest map layers near Port Washington, and every real data source behind Project Analysis
Road and stream map layers are still prototype content, standing in for surveyed GIS boundaries
Built around transparency
Data sources are identified
Illustrative data is labeled
Confidence is communicated
Professional review remains essential
Help shape the future of wildlife-conscious planning.
If you plan, engineer, or care about what gets built where you live, I'd love your feedback while we're still early enough for it to matter.
