The fastest growing activity on national wildlife refuges in the past ten years has been wildlife photography. That’s not surprising—the digital camera population explosion and cell phones with ever-improving picture-taking abilities are increasing the number of nature photographers at a rapid rate. You don’t need to purchase expensive equipment or have any experience to get started. A small camera or camera-phone will do just fine for most visitors. The Alder Island Nature Trail is a great place to take photographs of plants and wildlife of the refuge.
Just be sure to give wildlife space, do not change their behavior to get a "better" photo with a smartphone.
