Credit: (Courtesy NJ Department of Environmental Protection) New Jersey’s 2007 “duck stamp” featured a painting by Michael Braun of a Chocolate Labrador Retriever puppy examining a green-winged teal decoy; the decoy was carved by the artist’s father, Ed O. Braun Jr. It was 1996 when New Jersey last raised the price of its “duck stamp,” the required — and once famously collectible — waterfowl hunting permits that help fund wetlands and other environmental projects throughout the state. That may be about to change. A move is underway to double the modest $5 fee for residents and boost the funds for needed projects — all with the apparent support of hunters themselves.
