About Terrapin Watch
Terrapin Watch is a community science project that engages Long Islanders in an effort to monitor and record the distribution of diamondback terrapins in our region. Participants are simply asked to report any diamondback terrapin sightings through our data collection system. Reports can be submitted through the data form below or on a mobile device through the free Survey 1-2-3 app.
