Amphibian Tracker 2016

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.

The first day of spring, and a Nor'easter is potentially headed up the New England Coast, slowing things down again in the amphibian world.

Update 3/9/2016

Wood Frogs and Spring Peepers are calling in the University of Connecticut area. With the unseasonably warm temperatures and rain in the immediate forecast, we are eagerly anticipating amphibian migrations on a large scale this week.

Update 2/25/2016

The warm rains that moved across the eastern US have started the amphibian migrations. Salamanders and frogs moving towards breeding ponds have been reported in Missouri, Ohio and New Jersey.

Our first report of Spotted Salamander egg masses has come in! Tom and Deb Mann observed the first egg masses of Spotted Salamanders in Clinton, MS, on 26 December 2015.

Movements of Spotted Salamander males have been reported in December and January this winter in the Northeast with the unseasonably warm temperatures and rains.
