Almond Marsh

Almond Marsh is home to a great blue heron rookery and rare sedges.

Open Saturdays April–June

While there are no trails here, the site is a favorite among birders. On a good day, an astute observer may sight dozens of species of waterfowl and raptors, including the Cooper's hawk and peregrine falcon.

Our dedicated rookery volunteers open the preserve to visitors Saturdays from 8 am to noon, April through June (except Memorial Day weekend) for rookery and waterfowl observation. Volunteers provide viewing scopes, binoculars, and bird books to enhance your viewing experience.

The entrance is on the west side of Almond Road, north of Casey Road and south of Route 120.

The parking area is open Saturdays from 8 am to noon, April through June (except Memorial Day weekend) for rookery and waterfowl observation.


The Natural Scene

The highlight of this site is the significant marsh and sedge meadow complex. Approximately 110 acres here enjoy added protection as a dedicated Illinois Nature Preserve. The entire site is part of the larger Liberty Prairie Reserve, a collaboration of public agencies and private landowners to create a significant landscape of continguous open space in Libertyville Township.

Almond Marsh provides a great spot for migrating waterfowl to rest and forage. Many different bird species have been documented using the preserve, including the state endangered black-crowned night heron and king rail. Great blue herons have been an iconic species at this marsh for decades, but the natural deterioration of tall trees recently has caused a decline in nesting sites for this species.

With help from the Lake County Audubon Society and Integrated Lakes Management, Inc., the marsh now contains 12 man-made nesting platforms to provide continued nesting locations for great blue herons. Since the project began in 2009, these man-made platforms have been adopted by heron families, and Almond Marsh continues to be a great place for this species to nest and raise young. Our wildlife biologists hope that this pilot project may help with breeding efforts of other platform-nesting species, such as ospreys, at other locations in future years.
