Eric W. Sanderson Eric Wayne Sanderson is an American Landscape ecology landscape ecologist, who served as the inaugural director of the Mannahatta Project. Quotes Conservation biology Conservation biologists struggle to decide how many animals to save. In this article, I outline 18 approaches to setting population target levels (PTLs) for animals, with rules of thumb and analytical recommendations for each approach. Minimum viable population Minimally viable populations, the most common target level, are necessary but not sufficient for most efforts, given the range of values that bear on conservation. Reference ecosystems, either extant or historical, are key for setting practical target levels. Setting PTLs sufficient for conserved populations to be animals in all respects (including functional, social, landscape, ethical, aesthetic, and spiritual aspects) is a critical consensus point. In many cases densities as well as overall population size will need to be specified. I suggest a four-tiered system of setting incrementally higher population target levels such that conservation provides first for demographic sustainability, then ecological integrity, then Sustainability sustainable use, and finally Ecological restoration restoration of historical numbers of wildlife, based on times when human beings had less impact on the planet than we do today. How Many Animals Do We Want to Save? The Many Ways of Setting Population Target Levels for Conservation BioScience 56 11 November 2006 911–922 10.1641/0006-3568(2006)56[911:HMADWW]2.0.CO;2 On a hot, fair day, the twelfth of September, 1609, Henry Hudson and a small crew of Dutch and English sailors rode the flood tide up a great Tidal river estuarine river, past a long, wooded island at latitude 40º 48' north, on the edge of the North American continent. Locally the island was called Mannahatta, or "Island of Many Hills." … Mannahatta had more Ecological community ecological communities per acre than Yellowstone National Park Yellowstone, more native plant species per acre than Yosemite National Park Yosemite, and more birds than the Great Smoky Mountains National Park. Mannahatta housed wolves, American black bear black bears, Cougar mountain lions, beavers, mink, and North American river otter river otters; whales, porpoises, Pinniped seals, and the occasional sea turtle visited its harbor. Millions of birds of more than a hundred and fifty different species flew over the island annually on transcontinental Bird migration#Long-distance migration migratory pathways; millions of fish—shad, herring, trout, sturgeon, and eel–swam past the island up the Hudson River and in its streams during annual rites of spring.

My task was to bring technical aspects of modern geography into its global mission to save tigers, elephants, whales, gorillas, and other charismatic megafauna ... More than most disciplines, ecology thrives on complexity, and ecology in the service of conservation (a subdiscipline called conservation biology) pulls one rapidly into the domains of economics, society, and politics.

Sanderson Sanderson wanders through Central Park, he's able to look beyond the half-million cubic yards of soil hauled in by its designers, Frederick Law Olmsted and Calvert Vaux, to fill in what was mostly a swampy bog surrounded by Toxicodendron pubescens poison oak and Poison sumac sumac. He can trace the shoreline of the long, narrow lake that lay along what is now 59th Street (Manhattan) 59th Street, north of the Plaza Hotel, with its tidal outlets that meandered through salt marsh to the East River. From the west, he can see a pair of streams entering the lake that drained the slope of Manhattan's major ridgeline, a deer mountain lion trail known today as Broadway (Manhattan) Broadway.
