Amphibian Tracker

With the help of researchers and citizen scientists throughout the eastern United States, we track the annual migration of spotted salamanders, wood frogs, and spring peepers to their breeding ponds. We ask folks who see these amphibians in their community to share their observations with us via email or through the form below. The data we collect is uploaded to a Google map and color-coded by date to show overall trends in the timing of migration, and allows us to examine what environmental factors might trigger migration events - for example, temperature and precipitation.

Reports are in from Mississippi of the first Spotted Salamander eggs at their sites.

Amphibian activity is increasing in the northern regions of the east coast. Frog and salamander breeding has been reported from the mid-Atlantic states up to New England as we experience unusually warm and wet weather.

15 March

Amphibian migration and breeding activity in the Northeast has been put on hold due to three Nor'easters in the past couple of weeks.

29 March

After the fourth Nor'easter in a month, the Northeast is beginning to thaw, and amphibian migration and breeding activity is picking up again. Wood frog egg masses laid before the wintery storms experienced high mortality. Spring peepers are making their aural mark on the northern soundscapes.
