On behalf of Audubon New York, MNLA created a landscape master plan for the Theodore Roosevelt Sanctuary in Oyster Bay Cove, the first Audubon songbird sanctuary in the nation. The master plan clarifies circulation routes, re-envisions existing structures, establishes native plant demonstration gardens, and creates a welcoming entry to the site. The plan also provides strategies for improving bird habitat, controlling invasive species, and managing stormwater with green infrastructure. The central gathering area features a restored bronze fountain by the American artist Bessie Potter Vonnoh (cast in 1925). The project has been implemented in phases and is now open to the public.
