The birding trails along Grand Isle consists of nearly sixty acres of marsh and chenier habitat and are divided up into six tracts that are managed by the Louisiana Nature Conservancy and the Grand Isle Community Development Team. The trails mainly consist of tracts procured by the Grand Isle Nature Conservancy or donated by local landowners. However, because some of the boundaries of the tracts are partially fragmented, the chenier habitat can sometimes expand into private property. But due to the increased popularity of the Migratory Bird Festival, private landowners will generally allow bird watchers and ornithologists permission onto their land. Some residents will go as far as to post signs that say "Bird Friendly" as a way to invite bird watchers onto their property.
