The Mannahatta Project is a Wildlife Conservation Society research project in historical ecology led by landscape ecologist Eric W. Sanderson that principally ran for 10 years, from 1999-2009, reconstructing the island at the point of first contact between the Dutch ship Halve Maen and the Lenape in 1609. The work culminated in the publication of Mannahatta: A Natural History of New York City in 2009, and has subsequently developed as the Welikia Project and in influence on other environmental initiatives. The project has explored the great biodiversity and ecological complexity through a historical geographic information system based on georeferencing of the British Headquarters Map of 1782 and the Randel Farm Maps made for the Commissioners' Plan of 1811, while also detailing the formative impact of Native American use of fire in ecosystems. It culminated in 2009 for the 400th anniversary with the publication of the book Mannahatta: A Natural History of New York City, which also includes a speculative look forward to the effect of climate change on New York City and hopeful human adaptations in the year 2409. An exhibition at the Museum of the City of New York was held the same year. More information...
