The J.N. “Ding” Darling National Wildlife Refuge on Sanibel Island will introduce its latest educational tool, the Roving Ranger, starting April 8. Roving Ranger will be the first such vehicle in the national refuge system. Compact, nimble and easy to set up, it will be visiting libraries, churches, parks and events throughout Lee and Collier counties to share information about the refuge and educate the public about conservation issues. Refuge educators will greet visitors through a window on the side of the truck and at informational tables and hands-on exhibits outside of the vehicle. It also will serve as a starting point for tours and other activities. The selfie station on the back side of the Roving Ranger will showcase a framework of refuge creatures, including a manatee, a roseate spoonbill and other birds.
