The Natures of San Francisco

Although ecosystems are the most living areas of cities, they remain hidden from view on city maps of the built landscape or paved roads that define the mobilty of “urban” life.  But we fail to orient ourselves to the extent of urban environments and compromise our demand for livable space by relying on maps’ abbreviated conventions.

For doesn’t any map server foreground a selective level of local detail, replicating a dominant focus on roads, paved spaces, and buildings, to the exclusion of the constricted habitat that remains on the edges of a city’s built space?  While San Francisco was long a center for nature preservation, and indeed the preservation of the country in the city, as the perceptive Bay Area geographer Richard Walker put it so eloquently, the organization of tools  to uncover and preserve the current relation between ecological niches, natural environments and the built city becomes the project of the recent Nature in the City map, with offers new symbolic tools built on data to explore the urban environment.  The distinct base-map that Nature in the City organization has adopted to invite us to view San Francisco in its most recent revisioning of the green spaces that are distinguish the City by the Bay, rather than the rush of commuting and explosion of jobs and rents for which the Bay Area may be increasingly known–

–by using a base map rich with data sets of the multiple green spaces in the city, from parks to all street trees and gardens, as if they and the surrounding waters afforded a palette

–by which to situate the existing habitat that Nature in the City has allowed to encourage, and would allow viewers to focus on the habitats of specific animals, birds, fish, and plants across its urban space, in a static map that is made for an audience familiar with interactive mapping forms, and the coding of a rich natural space, extending to imagining its lost estuaries, underground rivers and watersheds, and even the historical shorelines of San Francisco before the addition of landfill.

By orienting us to the lived reality on the ground, shores, and waters around San Francisco, the recent remapping of open spaces in San Francisco by which local environmental non-profit Nature in the City has taken the time and effort to refocus attention from its buildings or paved environment, inviting us to appreciate the work of the non-profit in planning active green spaces in the urban space that San Francisco contains by representing the city’s urban space in a distinct cartographic idiom:  as Nobel Laureate Thomas Tranströmer wrote of how the disbelief of Henry David Thoreau “disappear[ed] deep in his inner greenness artful and hopeful,” cartographers worked to allow readers to detecting habitat within the urban environment in a distinctly Thoreauian marveling of how natural habitat exist within a city that goes often undetected and–as only a map can remind us–isn’t hidden but overlooked.

Nature in the City 2018/draft

Nature in the City paper map helpfully addressed a general reader in the age of bespoke data-heavy maps, coded for individual  uses, using graphics to hone a rich set of databases to invite all readers of the map to examine the intersection of layers of greenspace, parks, and urban trees provide a surface that any viewer can navigate to reacquaint themselves to urban space that questions its edges, centers, and the frame of a greater ecosystem of which the “city” is the microcosm and condensation:  the countryside that we place outside of the walls of the city–extra muros–is revealed to lie instead at its center, emblematized by the coyote who raises his or her head as if to exult in being present in the remaining green environment–a sort of pictorial designation of the indexical deictic reminder “YOU ARE HERE.”  The observer is decentered, for  a moment, in the map however, as one examines where species are located, as if in the recent Nature in the City challenge.

The claim that is invested in most tourist way-finding maps is repeated by the images of a sand dollar, magnolia, jackrabbit, California Poppy, shorebird, whale and two butterflies–each included in the key of the map on its left margin–to remind map readers that “they” are here, inviting discovery from visitors to the city its real urban spaceMuch as a legend to the left margin invites you to cross-reference them with landcover, the icons of animals suggest something like a hide-and-seek game for visitors to explore the actual urban environment and its riches of habitat–habitats that Nature in the City has often encouraged.

The claims of copia and urban abundance that was classically associated with chorographic views of Renaissance cities is almost displaced onto San Francisco’s nourished ecosystem in ways that Nature in the City encourages; the map involves  viewers by inspires endless exploration in ways that attests to its own truly inventive design.  Indeed, the involvement of a distinctly innovative battery of representational tools invite viewers to observe the city as it is rarely seen or perceived.  Indeed, while one usually thinks of coastal California as sites of extreme settlement and habitation–

Although pioneering aerial photographic imagery exists of the prewar space of San Francisco, a fantastic hundred and sixty four aerial photographs pioneered by Harrison Ryker from an airplane that left from the Oakland airfields, which offers a detailed image of the foliage, open space, still sandy regions, and of the city in crisply detailed black-and-white composite photographs–

–that invite viewers to examine its detailed imagery through the stereoscopes Ryker would patent upon opening shop as an East Bay map-maker.  The aerial photographic map promised a precision and detail that foretold remote sensing, and anticipated the deal of the Nature in the City map, despite its monochrome:  the view it offers of the lines on playing fields, basketball courts, and paths in the Golden Gate Park promised a visibility that would make it appealing in World War II, in ways that prefigured the pointillistic accuracy of remote aerial sensing.  The crisp local detail recently that was recently made available in interactive form online by the indefatigable Donald Rumsey lets one  navigate the composite record of now lost shorelines, the fluid ocean coastline, once-sandy Outer Sunset, Golden Gate Park and Duboce Hill–

–of the same expanse of the recent Nature in the City map in a way that anticipates the detail LiDar surveys of the city by the bay.  The non-profit updated the accuracy of local detail of the crisp black and white composites from the interactive map Rumsey Associates crafted, allowing us to examine current habitats, ecosystems, and animal life within the city and the surprising taxa that inhabit its denser blocks, after the addition of highways, a far denser downtown, in ways that allow the areas of tree cover of different heights to pop at the viewer to suggest the lush urban canvas in which they live, and the map to pop in into three or four–if one counts the temporal of the lost coastal shoreline, inviting viewers to witness and negotiate a sort of counterpoint between built space and remaining urban ecosystems, and directing attention to the overlooked.  The new synthesis of art and cartography accomplished by Lindsay Irving and artist Jane Kim expand and enrich over 500 datasets to fashion a new symbology of pictorial cartography across time, inviting us to compare shorelines, interrogate built spaces, and consider the city not entirely a human space but one from which we benefits where green cover and contact with a range of animal species persists and survives, using code that tracks the growth of urban habitat to provide the basis for a richly interactive tour of the city’s natural resources–a record interactive not by mouse, but by interpretation, inviting viewers to excavate historical habitats for birds, marine mammals, insects, and butterflies, in not only a “deep history” of place, but a deep ecology of the ecosystem that underlies the city as a palimpsest.

What would it look like, asked the designers and cartographers at Nature in the City, a local San Francisco-based non-profit, to fashion a dynamic map that reveals the habitats that  flourish–and even be nourished–within an urbanized space.  In so doing, the layers of the map act to orient readers to  a counter-map of the built city, foregrounding the spaces of habitat that the group has encouraged across San Francisco and that actively exists on its streets and in its yards.  The new model of urban exploration in the map that is used in the header of this post is based less on navigating the urban space we know, than exploding the nature/urban dichotomy, and pointing us to the cites where nature has taken shape in the urban environment.  The result shocks the viewer, actively inviting them to recalibrate their own reaction to urban space far more actively–and in a more engaged fashion–than one experiences when reading urban maps.  And the practice of reading the map is not only engaging, prompting new activities of looking at one’s own neighborhood or cycling and running route,–but also extremely fun.
