Urban Land Trusts -- A Guest Commentary

 

February 23, 2006 — By Steven J. Moss, San Francisco Community Power

Millions of dollars are spent internationally each year to buy and protect

wilderness areas. Large swaths of old-growth redwood forests in the Pacific

Northwest, rain forests in South America, even swamp lands in the southern

United States have been purchased by government agencies and private trusts. Yet

hardly a dime is tossed towards systematically reclaiming urban eco-systems.

With a majority of the world’s population soon to live in cities, it’s time

to focus on recreating sustainable wilderness areas in our own backyards.

 

Urban green spaces have traditionally consisted of vacant lots, “pocket

parks,†and, in some cases, larger expanses of what might be called

artificial-natural recreational areas – Central Park in New York, Golden Gate

Park in San Francisco, Rock Creek Park in the District of Columbia. In some

cases these citified wilderness areas provide important habitat to native and

imported species, ranging from frogs and birds to even coyotes and mountain

lions.

 

But, by and large even the largest urban parks can hardly be considered

thoughtful expressions of eco-system preservation. They tend to be too small to

suitably house migratory, or even “walk about,†species, and hyper-focus on

activities inside their boundaries, ignoring what happens to a plant or animal

once it leaves the park.

 

There are emerging exceptions, in which significant care is being taken to

reclaim land to close to its natural state. In San Francisco, Crissy Field,

which for decades was the site of an abandoned and decaying military outpost,

recently was transformed back into wetlands. The nearby Presidio, another former

military installation, likewise is being slowly altered to be more hospitable to

native plants and animals. But even in these cases while significant public and

private sector dollars have been invested into restoration efforts, almost no

attention has been paid to an issue central to true wilderness preservation –

whether the protected area is large enough to provide a home to naturally free

range species.

 

In the absence of thoughtful human intervention, urban animals have found their

own way to roam. Relying on an unintentional patchwork of backyards, vacant

lots, street medians, and other green spaces, raccoons, coyotes, quail, and

snakes find ways to travel through cities in search of food, shelter, and mates.

But they risk being squashed by cars, eaten by cats, and poisoned by household

chemicals. Less hardy species don’t have a chance.

 

The way to solve this problem is to start treating urban areas as potential

wilderness, map out land purchase or protection strategies, and begin making the

right investments. Thousands of creeks are hidden beneath city streets and

backyards, waiting to be re-discovered, as are historical migration pathways for

birds, mammals, reptiles, and insects. Rather than slapping up sterile pocket

parks or requiring deeper lawn-planted setbacks on new developments, networks of

green spaces could be formed in a way that creates thriving, integrated,

regional wildness areas.

 

My own San Francisco backyard, located in one of the least green areas of the

City, is adjacent to six other backyards which, if thoughtfully directed, could

form the basis for a sustainable chain of green areas through the region. Rather

than just rats and spiders – as well as more exotic creatures – my small

property could serve as an integrated habitat for a host of plants and animals.

 

While undertaking this strategy may be expensive – urban land is typically

more costly to buy or “encumber†than remote wilderness areas –

substantial existing resources could be leveraged on its behalf. For example,

rather than charging case-specific “mitigation fees†for new construction,

or requiring site-specific set-asides, new developments could be assessed a

municipal wildness reclamation fee. A nascent effort to develop such a system is

currently emerging in San Francisco’s Dogpatch neighborhood, where large

swaths of formerly industrial land are being hungrily eyed by developers.

 

More than a century ago forward-thinking civic leaders set aside valuable land

in rapidly growing cities to create now essential green spaces. It’s

impossible to think about Manhattan without Central Park, or San Francisco

without Golden Gate Park. It’s now time for a similar vision to transform the

uncompleted business of greening our cities into a thoughtful expression of our

deep need for wilderness. After all, while several thousand people may visit the

Headwaters Forest in Northern California each year – protected at a cost

upwards of a billion dollars – millions of people would visit an integrated

and sustainable eco-system in Chicago, Rio, or Delhi. That’s worth paying for.
