Our First-Sunday-of-the-Month for July is on Independence Day. This free two-hour guided nature walk starts outside the Meadowlands Environment Center in DeKorte Park in Lyndhurst, and runs from 10 a.m.
   We’ll walk around the square-mile park, looking for Black Skimmers, butterflies and various egrets and herons. The walk is run by the New Jersey Meadowlands Commission and the Bergen County Audubon Society.
