On rainy nights on the cusp of spring, an amphibian’s natural clock sends out the alarm that it’s time to migrate to vernal pools and begin the breeding process. Teatown educators patrol the roads surrounding Teatown, monitoring the small and slimy as they attempt to cross the road, reporting their findings to the NYS DEC Amphibian Monitoring Program.

American eels are migratory fish that are hatched in the Atlantic Ocean and enter rivers as tiny “glass eels” each spring. The species is in decline over much of its range, and baseline studies are needed for conservation. Teams of citizen scientists collect glass eels using nets and traps in over a dozen Hudson River tributaries from Staten Island to Troy. Teatown educator Marie Perry explains how juvenile fish are counted, weighed and released to better upstream habitats, often above dams, and how you can help protect this critical species by joining the Eel Project as a volunteer.
