Mannahatta Project

Mannahatta Project is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mannahatta Project rather than just read about it. In short: The Mannahatta Project is a Wildlife Conservation Society research project in historical ecology that ran from 1999 to 2009, reconstructing the landscape of Manhattan Island as it would have existed in 1609 at the point of first contact between the Lenape people and the crew of the Dutch ship Halve Maen ("Half Moon"), captained by Henry Hudson.

Key takeaways

Mannahatta Project belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Mannahatta Project to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mannahatta Project from memory before moving on to harder problems.

Reference excerpt

The Mannahatta Project is a Wildlife Conservation Society research project in historical ecology that ran from 1999 to 2009, reconstructing the landscape of Manhattan Island as it would have existed in 1609 at the point of first contact between the Lenape people and the crew of the Dutch ship Halve Maen ("Half Moon"), captained by Henry Hudson. The effort culminated in the publication of Mannahatta: A Natural History of New York City in 2009, and led to a follow-on effort called the Welikia Project. It has also influenced other environmental initiatives.

Project and book The project, which was led by landscape ecologist Eric W. Sanderson, explored the great biodiversity and ecological complexity of Manhattan Island 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. It also detailed the formative impact of Native American use of fire in ecosystems. The project culminated in 2009, marking the 400th anniversary of Henry Hudson's 1609 expedition, with the publication of a book called Mannahatta: A Natural History of New York City. The volume 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. Sanderson estimates that in 1609 the landmass of the island now called Manhattan contained 66 miles of rivers and streams, numerous fishable tidal inlets, 70 kinds of trees, "627 species of plants, 85 species of fish, 32 species of reptiles and amphibians, 233 species of birds and 24 species of mammals." Additionally, Sanderson describes the 1609 landscape as one tended to by the Lenape people, with geological evidence suggesting that the indigenous people leveled forests and fields of grasslands, and possibly engaged in small scale farming.

Later phase and influence A follow-up project for 3 years was the Welikia Project ("my good home" in Lenape), examining the whole geography of New York City, which ran from 2010-2013. A planned sequel book is tentatively titled The Welikia Atlas: A Natural History of New York’s Five Boroughs. The 2007 book The World Without Us includes a chapter "The City Without Us", inspired by the Mannahatta Project, that imagines a future depopulated New York City. As a benchmark in environmental history, the Mannahatta Project has influenced restoration ecology initiatives in the region. The Billion Oyster Project aims to restore the estuary to its state in 1609.

Worked examples

Example 1 — a first encounter with Mannahatta Project

Start with the simplest possible case. Write down what Mannahatta Project claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mannahatta Project before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mannahatta Project ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mannahatta Project

In research: Mannahatta Project appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mannahatta Project in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mannahatta Project is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1600s in the environment, 1609 in North America, 1609 in the Dutch Empire, so understanding it makes those chapters shorter.
In everyday life: Look for Mannahatta Project outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
