In 2011, an article in Wired magazine described the effort, and provided Williams' email address, encouraging anyone to write who might have data on existing moon trees. As of 2022, efforts were continuing to identify and locate existing trees; the NASA page remains active. In March 2021, the Royal Astronomical Society and the UK Space Agency asked for the help of the public to identify up to 15 Moon Trees that may be growing in the United Kingdom. As of April 2021, none of the trees that supposedly came to the UK have been identified.
