As temperatures rise, spring rains roll in, and the ground thaws, the amphibians of New York are preparing themselves for a great migration. On the 10th of March, a group of about 30 volunteers congregated near Hop Field at Thacher State Park armed with flashlights and buckets. With great excitement they looked along the road edges for salamanders and frogs, hoping to help them cross the road as the amphibians migrated to woodland pools. Throughout most of the year, mole salamanders and woodland frogs spend their time burrowed under rocks and leaves on the forest floor, but each spring salamanders and frogs can migrate up to a quarter mile to woodland pools to breed. The mass migrations to the vernal pools occur during spring rainstorms with temperatures above 40 degrees.
The rain was intermittent that night, and although spring peepers and leopard frogs were escorted across the road, no salamanders were found. The migrations typically happen in late March and early April, so there is still hope! On nights when the conditions are right, many nature enthusiasts can be seen on roadways close to wetlands helping the amphibians safely cross the road. If you are interested in getting involved in preventing vehicle related deaths during these mass migrations, contact your local State Park or local DEC office. These organizations sometimes coordinate volunteers to come together on rainy nights to help salamanders cross busy roads. The more volunteers there are to help, the more amphibians will successfully breed! Before you help the amphibians, be sure to brush up on your identification! Here is a sampling of the native amphibians that you could see in New York.
Mole Salamanders:
The spotted salamander is black and has yellow spots. It can grow up to 8 inches long. It is one of the most common salamanders in the area, and if you go out on a migration night there is a good chance that you will see it!
Frogs:
