Natural History Notes
Photo: Derek Yorks
- Majority of members of spotted salamander populations will migrate, often across roads, to vernal pools on “Big Night,” the first night of warm rain following the spring thaw
- Male and female salamanders perform an energetic mating dance after reaching the pool
- Following mating dance, females lay 2–3 globular egg masses containing up to 200 eggs each
Share Your Sighting
There is much still to learn about the distribution and ecology of Maine’s herpetofauna, and we encourage members of the public to share their photo-documented observations as part of the Maine Amphibian & Reptile Atlas Project (MARAP).
To see if a township still needs documentation of a species, consult this distribution map (PDF). If a township lacks a photo or specimen record, we want your observation!
There are two ways to share your observations:
No service? No problem. Click here to download the survey to your device while connected, then take offline to collect observations from anywhere. Tip: The survey works best on Google Chrome and Safari.
Or upload sightings to the iNaturalist citizen science project through their website at iNaturalist.org or mobile app.
- When submitting an observation through iNaturalist add a description of the location (and other noteworthy information) to the “notes” field. This serves as a check on the locations automatically generated by smartphone cameras, which may be imprecise if cell service or GPS coverage is weak.
Thank you for doing your part to help conserve Maine’s reptiles and amphibians.
