The Joppa Flats Education Center is located at the gateway to one of the country’s most productive year-round wildlife viewing areas — the Parker River National Wildlife Refuge and the Plum Island estuary. Highlights for visitors are the many species of birds that utilize the area’s extensive salt marshes, mudflats, rivers, bays, and coastal waters. During local area field trips, Joppa Flats program participants have recorded over 300 species of birds, including bald eagle, snowy owl, and many warblers, shorebirds, and waterfowl. The visitor center overlooking the Merrimack River includes a children’s education room with a marine aquarium, a conference center, art exhibits, a nature shop, butterfly gardens, and interpretive displays.
