Bio:

Eymund Diegel is a map maker and citizen scientist working with community groups in Sunset Park and Gowanus, Brooklyn to map the City’s Ghost Streams through a project called NY CSI (Creek Scene Investigation). He worked on the City’s first Sludge (polite term) Management Plan and is intimately familiar with sewer overflows. As forgotten streams and springs are directly tied to the city’s largest trees, he is now mapping the history of New York City’s forest in a search for the City’s largest, oldest tree.
