Mary Ann Brown Preserve

Louisiana

Located near Oakley Plantation where John James Audubon painted some of his famous bird paintings.

What makes this preserve unique?

This area supports a quality mixed pine-hardwood forest on the fringes of the Tunica Hills.  There is an interesting mix of native hardwoods with loblolly and shortleaf pines.  This site was donated to TNC by the late Mr.  & Mrs. L. Heidel Brown in memory of their daughter, Mary Ann.

Why TNC Selected This Site

The Nature Conservancy selected this site for its mature stand of hardwood forest, dominated by beech and southern magnolia.

What TNC Has Done/Is Doing

The Nature Conservancy of Louisiana has developed this site into one of our more accessible preserves because of its scenic beauty and relatively low sensitivity to public use. Mature beech-magnolia-holly forest, unusual topography, and high plant and animal species richness, make this preserve especially inviting to visitors. Stewardship activities have focused on trail construction, restoration of old fields back to diverse native forest, and control of non-native weeds.  

Steep slopes and a permanent stream are distinctive features on the property.  The combination of sweet loess (wind deposited) soil and the microclimate created by the deep ravines provides an environment with unique plant and animal life.  This uniqueness is demonstrated by the large diversity of woody plants found in the preserve.  In addition, the preserve affords an excellent opportunity for bird watching and the region is the only place in Louisiana to see chipmunks, which are highly visible during the warmer months.

Mary Ann Brown Preserve supports a mature stand of beech-magnolia forest. Several streams cross the property and are bounded by centuries-old beech and magnolia.  The combination of sweet loess soil and the microclimate created by the deep ravines provides an environment with unique plant and animal life.  This uniqueness is demonstrated by the large diversity of woody plants found in the preserve.  In addition, the preserve affords an excellent opportunity for bird watching.

A well-maintained trail/boardwalk system, approximately 2 miles in length, provides visitors with ready access to the preserve.  There are no public restrooms on the preserve, so plan accordingly.  The Main Loop Trail (1.3 miles) begins at the Trailhead near the front entrance gate, continues over numerous foot bridges through the preserve, past the pavilion, around the pond and returns hikers to the front gate entrance.  Hikers may add 0.7 miles to their hike by taking the Outer Loop, a spur trail off the Mail Loop.   If you are new to the preserve, please take a trail map, which are available at the information kiosk near the front entrance.  Please help us protect the preserve by keeping to the established walking trails.  Bicycles are not allowed on the walking trail.

The trail system is open to the public daily during daylight hours only.  Access is through a pedestrian passageway in the split rail fence at the front parking area.  The preserve features a covered pavilion and pond house, which are available for day outings.  Overnight primitive camping and the other preserve amenities are available to scout and school groups by reservation only.  Please call our office in Baton Rouge at (225) 338-1040 for more information or to make a reservation.  A refundable deposit is required and service projects coordinated through our office are much appreciated.
