Just upriver in Erie County from Niagara Falls State Park lies New York State’s third largest island. Home to more than 20,000 people and split by Interstate-190, Grand Island is 28 square miles and divides the Niagara River into east and west branches.
Industry and commerce dominated this river and its shoreline for more than a century, leaving a legacy of water pollution, fish unsafe to eat, and loss of wildlife habitat so extreme that in 1987 the U.S. Environmental Protection Agency (EPA) declared the entire 36-mile river an Area of Concern.
That federal listing set the stage for years of remediation efforts by New York State to clean up the river and shoreline. And now, it has led to State Parks, working with several partners, to begin the next chapter in healing the river – the restoration of several wetland areas of habitat along Grand Island critical for many fish and bird species that rely on the river for survival.
These projects focus on two State Parks on the island – the 895-acre Buckhorn Island State Park on the northern tip, a nature preserve which has some of the island’s best remaining marshland wildlife habitat, and the more-developed, 950-acre Beaver Island State Park on the southern tip.
With funding support from the EPA under a plan finalized in 2018, Parks staff have finished two habitat restoration projects at Grand Island and two more are under way this season.
At Beaver Island in the south, offshore rocky reefs have been added in the river to an area called East River Marsh to protect the shoreline from further erosion caused by boat wakes and wind. Thousands of native plants have been planted by hand to provide important habitat for fish and other wildlife.
In the north, Buckhorn Island has one of the largest remaining cattail marshes on the Niagara River. At a place called Burnt Ship Creek, contractors hired by Parks have created open water channels and “potholes” in the marsh to provide pathways needed for fish such as Northern Pike to feed and spawn. The new open spaces also allow sheltered nesting sites for such secretive marsh birds as the threatened Least Bittern, which prompted the conservation group Ducks Unlimited to partner with State Parks for this restoration project.
This season, parks crews are working at a place called Grass Island, which is not actually an island at all, but rather an area of shallow water filled with cattails and other aquatic plants, both above the water and submerged. Sometimes also called Sunken Island, Grass Island is just east of Buckhorn Island State Park across from the city of Niagara Falls.
In addition to cattails and other plants visible above the water, Grass Island is also made up of many acres of submerged plants, predominantly a species known as water celery or American eel grass. This plant provides food and cover for several types of fish, including the Muskellunge, the state’s largest freshwater sportfish, which spawns among the eel grass each spring. The Upper Niagara River is one of state’s most important habitats for this fish.
Above the water, many species of waterfowl and marsh birds use the island for nesting, feeding and nighttime cover. Pied-billed Grebes, a threatened species in New York, nest and raise chicks there in the summer. During the fall migration of Purple Martins, the birds will roost in the cattails by the thousands.
Together, Grass Island forms a 20-acre ecosystem designated as a protected wetland by the state Department of Environmental Conservation (DEC). While Grass Island provides some of the most important habitat in the Niagara River above the falls, this area has been steadily shrinking in recent decades due to wave erosion caused by boat wakes or wind. Between 2007 to 2018, Grass Island shrank by more than a third, losing an estimated 1.5 acres of its above-water vegetation.
This season at Grass Island, Parks contractors are constructing underwater rock reefs similar to those successfully constructed at East River Marsh. Once the reefs are finished, crews will add submerged tree trunks with the roots still attached (called rootwads) to provide underwater structure needed for good fish habitat. Also, large numbers of native wetland plants will be planted behind the protective rock reefs to expand the area with dense vegetation.
Also this summer, similar rock reefs, rootwads, woody material, and native plantings will be installed along the shoreline at Buckhorn Island State Park to restore and protect coastal wetlands. And finally, another similar project is in the works for the shoreline along the new West River Shoreline Trail at Buckhorn.
These projects join other ongoing conservation efforts at Grand Island being done by DEC, and the Buffalo-Niagara Waterkeeper, a not-for-profit conservation group. Find a FAQ on the projects here.
Buckhorn Island State Park is also a listed Bird Conservation Area, with its marsh providing important nesting habitat for threatened species such as Least Bittern, Northern Harrier and Sedge Wren. The marsh serves as a feeding, resting and breeding area for ducks, coots, moorhens, and rails. Common Tern find suitable habitat for foraging here. Additional birds of interest include a variety of species of ducks, herons, coots, moorhens, and rails. Spring and fall migrations along the Niagara River corridor can bring large numbers of gulls to this site.
Gorge-ous Gulls of the Niagara in Winter
The Niagara River is well-known as an international destination for its tremendous waterfalls, which form spectacular ice formations during the winter. Perhaps a lesser known fact, however, is that the river is also a critical haven for migrating birds during this time of the year. Gulls, in particular, are a common sight along the Niagara,…
Together, these wetland restoration projects at Grand Island aim to maintain and strengthen this urban island ecosystem in a river that fuels the spectacular waterfalls only a few miles away that draw millions of visitors each year.
If a visit to Niagara Falls is in the works, consider also making a trip to Buckhorn Island State Park and Beaver Island State Park, both of which have car-top boat launch sites, to see this part of Niagara River and witness some of the efforts to help restore it. Please remember that these are sensitive ecological areas and habitats for secretive wildlife, so be respectful and take care when visiting these special places.
As always, whenever hiking, or in this instance, more likely paddling, consider “Leave No Trace” principles to minimize your impact on the environment. Learn more on how to practice “Leave No Trace” by clicking on this previous post in the NYS Parks Blog.
Beaver Island State Park: This park has a half-mile sandy beach for swimming, adjacent 80-slip marina with both seasonal and transient boat slips, fishing access, car-top boat launch, multiple canoe/kayak launches, about four miles of bike and nature trails, nature center, playgrounds, picnic areas, athletic fields, horseshoe pits, an 18 hole championship disc golf course, an 18-hole championship golf course. In winter, visitors can snowmobile by permit, cross-country ski, snowshoe, sled or ice fish. Waterfowl hunting is allowed in-season by permit.
Also located in the park is the River Lea house and museum, home to the Grand Island Historical Society and built by William Cleveland Allen, cousin to Grover Cleveland who visited the family farm on several occasions.
Buckhorn Island State Park: For a wilder experience, try this less visited park, which is a nature preserve of marsh, meadows and woods that mark the last vestige of once vast marshlands and meadows that bordered the Niagara River. There are nearly two miles of nature trails for hiking, biking, and cross-country skiing. The preserve includes two launches for kayaks and canoes. There is ongoing restoration to re-establish wetland cover and water levels and increase the diversity of native flora and fauna. This effort aims to increase public access with more non-intrusive trails, overlooks and bird watching blinds.
