Margery Gallogly Nature Sanctuary

The Margery Gallogly Nature Sanctuary is a remarkable 145-acre oak and hickory forest. Big and Little Sixmile Creeks each flow through this unique landscape as they make their way to the Niagara River.

To visit the Margery Gallogly Nature Sanctuary, enter Assumption Cemetery on Whitehaven Road. The trail begins at the forest edge in the southwestern corner of the cemetery. There is a small parking area there for visitors. The trails are open to people walking, snowshoeing, or cross-country skiing. Bicycles, motorized vehicles—such as ATVs—horses, or dogs are not allowed on the property.

Ecological Importance 

The Margery Gallogly Nature Sanctuary is one of the largest, undeveloped, privately-owned properties left on Grand Island, and one of the largest remaining forests in the entire Niagara River watershed. The property includes almost a mile of Little Sixmile Creek, a tributary of the Niagara River.

The forest’s landscape was carved by the last glaciers and massive prehistoric floods, leaving behind vast wooded wetlands reminiscent of cypress forests in the bayous of the Southeast. In fact, the combination of oaks and hickories is more typical of forest further south of New York State, and represents what may be a newly described plant community.

This sprawling forest is also teeming with life. Passing migratory songbirds rest on the limbs of tall trees, while blue-spotted salamanders make their home on the forest floor below.

Community Support 

In September 2018, the Land Conservancy exceeded our fundraising goal of $800,000. This funding enabled us to purchase the property and begin work to create an even better walking trail system, restore wildlife habitat, and help maintain the preserve into the future.  The project was supported by a $568,000 grant from the Niagara River Greenway Ecological Standing Committee and an additional $200,000 from the Gallogly Family Foundation to help create the new nature preserve. The preserve is named the Margery Gallogly Nature Sanctuary in honor of that donation.


The Land Conservancy is grateful to every donor who made this sanctuary a reality. If you are interested in supporting the Land Conservancy’s work to protect places like the Margery Gallogly Nature Sanctuary, you can make a donation on our online giving page today.
