Vernal Pool Exploration Hike
Mar 31 @ 6:30 pm – 8:00 pm

With temperatures rising, the forest floor will be hopping with new life as frogs and other amphibians crowd into shallow puddles of water to breed and lay their eggs. These puddles, better known as vernal pools, provide a perfect opportunity to learn more about Mother Nature here in New Jersey. But hurry! They disappear quickly.

GSWA’s annual Vernal Pool Exploration provides a fun, outdoor learning experience for kids and adults alike. Discover the differences between a spring peeper, a chorus frog, and a wood frog. Find out how far an endangered spotted salamander will walk to find a mating pool. And, learn how much everything we have come to appreciate about the springtime depends on a few unassuming puddles of water on the forest floor.

Warm clothing and waterproof footwear — especially hiking boots — are very strongly recommended for this hike. Registration required. Register online or by calling 973-538-3500.

Calling all would-be explorers, adventurers, and buccaneers! The Great Swamp Scavenger Hunt is back for another year of outdoor fun!

Think you know a thing or two about New Jersey’s Great Swamp? Then it’s time to test your powers of navigation and observation to find out.

Begin the Scavenger Hunt just after 10 a.m. by checking in at GSWA’s Home Base under the pavilion at the Great Swamp National Wildlife Refuge’s Helen C. Fenske Visitor Center. (The Visitor Center is located just inside the Lee’s Hill Road park entrance at 32 Pleasant Plains Road in Harding Township, NJ.)

We will provide you with a route to travel, questions to answer, and a list of treasures to find throughout the 55-square-mile Great Swamp Watershed region. It’s your job to navigate to each treasure site, seek answers to the questions and riddles provided, and then return to Home Base with all your spoils.

A free cookout waits for all who participate, so don’t forget your barbecue enthusiasm. We love it when our guests participate in the picnic! Feel free to bring along a covered side dish (to share or not). We’ll supply the burgers, dogs, and drinks.
