Eastern: Otter Creek Preserve

Otter Creek Preserve
© The Nature Conservancy

Why You Should Visit
Otter Creek is not just scenic; as a productive tidal marsh, it provides essential habitat for migratory birds, stabilizes the shoreline and protects the land against erosion, and filters pollutants from water that drains into Long Island Sound.

Location
Mamaroneck, Westchester County, New York

Size
27 acres

How to Prepare for Your Visit
Please see our Visitation Guidelines.

Directions

  • From I-684, take 287 East.
  • Take Exit 11, Route 1 south (Boston Post Road).
  • Travel 3.4 miles and turn left onto Taylor Lane.
  • Continue 0.4 miles to the "Private Road" sign.
  • Park on the right side of the road and walk through the gate to the preserve entrance sign.

Trails
A half-mile loop trail traverses the preserve. It will take you past the tidal marsh and creek for which this preserve is named, through deciduous forest, and along wet woodland depressions. Though the trail is short, the bird diversity can be extraordinary, so bring your binoculars and take time to examine the different habitats contained in this urban jewel.

What to See: Plants
Marsh vegetation is composed primarily of two related grasses: salt marsh cordgrass and salt meadow grass, a similar, smaller species. Giant reed, or Phragmites, forms a dense border around the marsh. The uplands contain mixed deciduous forest dotted with vernal pools. Silver and red maples, black oak, sassafrass, and willows are abundant.

What to See: Animals
Black crowned night herons, osprey, yellow warblers, great blue herons, white egrets and northern harriers are commonly seen at Otter Creek. A wide variety of waterfowl and other migratory birds make use of the rich marsh and estuary throughout the year.

Why the Conservancy Selected This Site
The Otter Creek tidal wetlands system plays a significant role in the ecology of the Mamaroneck area and accounts for at least five percent of Westchester County's productive tidal wetlands. It is an important resource for wildlife and features more than 100 species of plants, abundant marine and terrestrial life, and more than 100 species of birds. It was designated a Geologic Area of Particular Concern (GAPC) by the NY State Department of Environmental Conservation.

What the Conservancy Has Done/Is Doing
With help from volunteers and staff, the Conservancy is removing invasive porcelain berry plants from the preserve and restoring native plant communities. Trail displays and the entrance kiosk educate visitors about the threats posed by invasive species, and suggest alternatives to planting non-native species in local gardens.
