of their expansion plans in 2015. The garden was saved when Birnbaum produced a contradictory original document issued by the Frick clearly identifying the space as a permanent garden. Through TCLF, he has brought the names of forgotten landscape designers and stewards, particularly women like Ruth Shellhorn, an advisor to Walt Disney, and Harlem Renaissance poet Anne Spencer, to the forefront. "Women have literally shaped the American landscape and continue to today, but their names and contributions are largely unknown." In 2022, for the bicentennial of Frederick Law Olmsted's birth, Birnbaum issued an alert about the threats to a dozen of Olmsted's iconic green spaces noting the cumulatively negative impacts posed by climate change, coastal erosion and construction. Publications, oral history modules and film Birnbaum has written and edited numerous publications. His book Pioneers of American Landscape Design (2000), co-researched with Robin Karson and Laura Byers was called "the first of its kind in America." It is an encyclopedic catalog of landscape architects and public space planners and engineers. Other Birnbaum works include Shaping the American Landscape, Design with Culture: Claiming America's Landscape Heritage, Preserving Modern Landscape Architecture and its follow-up publication, Making Post-War Landscapes Visible. He has produced numerous oral history modules about practitioners in his field along with profiles of notable modern landscape architects like James van Sweden, Cornelia Hahn Oberlander, Lawrence Halprin and Paul Friedberg.
