Walk in the Wild invites you to join them at Old Pine Farm Natural Lands Trust at 7 p.m. on April 15 for an evening of frog and toad exploration. Attendees are asked to meet at the Willoughby House and to dress appropriately for a night walk.

New Jersey is home to 17 species of frogs and toads each of which can be identified by their characteristic calls. Since they are primarily identified by their vocalization, the walk will begin at night when they begin their calling. Guests will enjoy a short discussion, listen to recorded tapes of calls and then walk down to Old Pine Farm’s waterfront area to experience the sounds firsthand.

Leader Carl Ford, who holds a degree in horticulture from Rutgers University, has spent his years as a nurseryman in Salem County. After retiring, he spent 10 years as a citizen volunteer in the Calling Amphibian Monitoring Project (CAMP) to identify and estimate numbers of each species over a predetermined 15-mile route in Cumberland County.

Cost: Free. Location: 340 Pine Ave., Deptford, NJ. For more information, call Charles White at 856-217-9138.
