Have you ever wondered what New York was like before it was a city? Welcome to Mannahatta, 1609.
MANNAHATTA A NATURAL HISTORY OF NEW YORK CITY
Eric Sanderson is a landscape ecologist with the Wildlife Conservation Society, and this book culminates ten years of primary research into the ecological history of Manhattan—The Mannahatta Project. Sanderson and his colleagues have reconstructed Mannahatta at the scale of a city block using the latest techniques in computational geography and visualization that allow them to recreate what Manhattan looked like in the hours before Hudson arrived. The story of the project’s creation touches on George

Chapter One
The Mannahatta Project As the moon rose higher the inessential houses began to melt away until gradually I became aware of the old island here that flowered once for Dutch sailors’ eyes—a fresh, green breast of the new world. Its vanished trees . . . had once pandered in whispers to the last and greatest of all human dreams; for a transitory enchanted moment man must have held his breath in the presence of this continent, compelled into an aesthetic contemplation he neither understood nor desired, face to face for the last time in history with something commensurate to his capacity for wonder. — F. Scott Fitzgerald, The Great Gatsby 1925
Mannahatta, 1609.

chapter two
The first time I walked through New York City I wondered what giant or god had created such a place. Buildings like cliffs, avenues like canyons, traffic flowing like rivers, parks brimming with forests and urban fields, a landscape populated by people seemingly from every nation and all parts of the continent, moving rapidly and with a deliberate attitude about their business, even if that business was none at all. I was intoxicated. I felt amazed at the ambition of the place and humbled by the power that had created it, for neither giants nor gods had built the “awful & grand” city; generations of New Yorkers, poor and wealthy, native and immigrant, had created the metropolis over a span of nearly four hundred years. Those people had each come for their own reasons, with their own peculiar visions, to this particular piece of land and shore and decided through some strange, collective logic, to raise a city on a scale beyond the power of the imagination to conceive. A law professor once described to me lying beneath the pillars of the George Washington Bridge as a child, cupping his hands around his eyes, and peering up the river to imagine the view that Henry Hudson might have seen as he sailed in on his small wooden ship. Jacob Astor, the industrialist, imagined a city where the wealth of an entire continent could accumulate in the hands of just a few men (and preferably one). Robert Moses, the planner, had a vision for New York City that included the automobile and access to ball fields and swimming pools and, in the midst of the Great Depression, reconfigured the city for the future. Michael Bloomberg, the recent mayor and billionaire, envisioned a future where the economy always hummed, with less traffic congestion, no smoking, and better subways. Hudson’s vision, to the extent that he had one, was to get rich and then get out of town. Adrian van der Donck, the Jonkheer who gave his name to Yonkers, New York, came to New Netherland in 1641, stayed, and became wealthy. He wanted others to join him and populate his lands; he wrote a lengthy paean to his new home called the Narrative of New Netherland (1650), describing the land as “naturally fruitful and capable of supporting a large population, if it were judiciously allotted according to location. . . . [It] is adapted to the production of all kinds of winter and summer fruits, and with less trouble and tilling than in the Netherlands. . . . The air is pleasant here, and more temperate. . . . ” Many others agreed, describing not only the “sweetness of the air” (Daniel Denton, 1670), but also the “wonderful size of the trees” (Johann de Laet, 1633), “all sorts of fowls, such as cranes, bitterns, swans, geese, ducks,

top The Visscher Map, circa 1651, shows northeastern North America as the Dutch understood it in the years following Henry Hudson’s voyage. Manhattan is at the center of the map, at the mouth of the Hudson River, which in turn is the focus of the New Netherland colony. Europeans at the time knew the outlines of the continent, but were only beginning to explore its heart. bottom The inset image shows the small village of New Amsterdam as it appeared from just off the tip of Manhattan. Note the windmill, gallows, and rolling hills.

The British Headquarters Map, circa 1782–83, once described as a “topographical and historical encyclopedia” of Manhattan before modern development, shows most of the original hills, streams, shoreline, and wetlands of the island.

top Freshwater wetlands form complex mosaics that vary according to how often and how deeply they flood. Sunny and wet, they are strongholds of biodiversity. These wetlands in Sterling Forest State Park, in Orange County, New York, are similar to those that were found on Mannahatta. bottom Deep emergent marshes, like these recreated at the New York Botanical Garden, form in deep standing waters.

these elements function as a subject, other times as an object. Each connection is a relationship based on food, shelter, water, or reproduction, or in the case of abiotic elements, on physical process dependencies like soil formation or how topography defines slope and slope determines water flow. In honor of Muir and his insight, I called these new networks “Muir webs.” They became the key, the magic decoder ring, to mapping where all the plants and animals of Mannahatta occurred those four hundred years ago. In its initial iteration, the Muir web built on the list of likely species contained a total of 1,623 elements, comprised of 80 percent species or groups of species, 10 percent abiotic elements or groups of elements, 5 percent ecological communities or groups of communities, and 5 percent “combinations,” composed of living and nonliving elements. In other words, species dominated the network, but the abiotic environment (the “fundamentals” of Mannahatta) was also strongly present, and various combinations of elements —whether of ecological communities or of life and not-life (the aspens near the stream)—were critically important. If species are like the people in a city, then by analogy this suggests that not only are relationships between people important, but so are our relationships to the infrastructure of the city (the buildings, the cars, the streets), to the neighborhoods (akin to ecological communities), and to the restaurants, offices, parks, and other places that only function when people come together (the combinations). Between those 1,623 elements, we wrote 8,245 explicit habitat sentences based on descriptions available in field guides and natural histories of the food, water, shelter, and, where applicable, reproductive requirements, of the plants and animals of Mannahatta. Many species are just passing through in September; they aren’t staying to reproduce (which is largely a spring- and summertime activity in the temperate northern latitudes), so their reproductive requirements are not included in the Mannahatta Muir web. Of the relationships in the 8,245 habitat sentences, 55 percent were central or primary relationships with other elements—the bread and butter of habitat relationships; 37 percent were relationships identifying membership within groups; and 6 percent were enhancing relationships—that is, relationships that were positive but not required parts of the habitat. The remaining relationships involved a small number of elements of lesser strength; very few were negative relationships that attenuated or excluded another species. These kinds of negative relationships were probably more important than this initial analysis would suggest, as we didn’t include the not-so-nice sides of nature—competition, parasitism, and disease. They represent the next frontier
