Update on Trees + Technology

After writing about the top 10 technologies for studying birds (based on a BirdScope article), I realized that I needed to update our Trees + Technology piece originally published on April 18, 2011.  Also, this post is our contribution to the fifth anniversary edition of the Festival of the Trees hosted by Via Negativa.

Nonprofits and municipalities have developed numerous ways to broadcast tree care and benefits information to residents.  In our original post we wrote about two of these: the Urban Natural Resources Institute (UNRI) "nutrition label" for urban trees and New York City's Open311 Wiki which maps calls made to 311 about tree issues.


Since April, we have come across several more of these technologies for sharing tree information.  The tag pictured above is from the Every Tree Counts and Chicago Trees Initiative campaigns and was sent to us by a reader in Columbus, Ohio.  Passersby can learn the monetary value this Ginkgo biloba provides to the City.  We wish the tag included the species name but the QR code in the lower right hand corner might lead to such information.


MillionTreesNYC developed ad campaigns like the "I'M SHADY" subway posters, seen above, encouraging New Yorkers to plant trees and to support the initiative.


Also, in New York is the work of Friends of Greenwich Street, a neighborhood improvement organization in Tribeca.  FGS runs the Tribeca Street Tree Project and as part of its outreach campaign has tagged trees in the neighborhood with posters encouraging residents to volunteer as stewards.  The poster in the photograph above was installed last season.

Finally, Casey Trees in Washington DC has designed three posters for its "25 to Stay Alive" watering campaign.  Based on precipitation and stream flow data, Casey Trees sends weekly watering announcements to residents through various media (Facebook, Twitter, and its homepage).  Residents are encouraged to water trees, especially young ones,* with 25 gallons of water during periods of little to no rainfall.**  The organization provides rain gauges to residents who signed a tree watering pledge as well as "ooze tubes" or slow-release watering bags.

* Young trees are defined as those that were planted within the last three years.
** Little rainfall is defined as an accumulation of less than 1.5 inches.

Let us know what your city is doing to encourage tree care and how your city is sharing information about tree care and tree benefits.

Original post, 4/18/2011: Two technologies have been on our minds lately.  The first is the "tree benefits label" and the second is NYC's Open311 Wiki.
Image: Tree Nutrition/Benefits Label, Urban Natural Resources Institute (source)
You are familiar with nutrition labels on packaged foods.  Now, the Urban Natural Resources Institute (UNRI) has developed a "nutrition" label for urban trees.  UNRI in partnership with the Massachusetts Department of Conservation and Recreation, UMass Amherst and the Town of Amherst created labels showing the ecosystem benefits produced by trees.  The project was implemented at the Amherst Sustainability Festival in 2010.  Forty trees were surveyed using software developed by Casey Trees, and urban forestry nonprofit in Washington, D.C. Each label is bar-coded to "attract" the attention of passers-by.  (These bar codes are not scannable QR codes or Microsoft Tags.)

Residents of NYC can call 311 "to get information, report problems, and request services."  These actions can be taken online, too.  In February, the NY Times reported that Mayor Bloomberg had launched an online mapping service for 311 calls.  Maps can be charted by location type, service request category, and complaint type.  Here is a map of new tree requests made between January 1 and April 7, 2011 in Community Board 2 (Manhattan).


Wired Magazine has an amazing graphic of the most common calls to 311 made between September 8 and September 15, 2010.  Damaged trees calls peaked at 10 a.m., 12 p.m., 2 p.m., and 7 p.m., while overgrown trees/branches calls peaked noticeably at 1 p.m.  Can anyone explain these patterns?

This Wednesday, April 20, at 11 a.m. (Eastern), Urban Natural Resources Initiative (UNRI) will host Melanie Kirk's presentation on using social networking tools to develop urban natural resources programs.  Melanie holds a Ph.D. and is an assistant professor and extension urban forestry specialist at the Texas AgriLife Extension Service.  More information can be found on the UNRI webcasts page.

Under Cape Cod Waters by Ethan Daniels

Image: Under Cape Cod Waters cover (source)
Many years ago we spent time in Cape Cod and the Islands.  In preparation for the trip - and this is something we do for all our trips - we read several books about the place.  Our list included The Emperor of Ocean Park by Stephen L. Carter, The Wedding by Dorothy West, and The Outermost House by Henry Weston.  If we were making that trip today, I would add Under Cape Cod Waters by Ethan Daniels.  We won a copy of the book in contest sponsored by Union Park Press in April contest.

Under Cape Cod Waters is a large format book.  Daniels's photography is spectacular and a conventional book format would have diminished his photographs.  How did he manage the close-ups that abound in the book?  I am more of a terrestrial person than an aquatic one but the concepts Daniels's addresses in the book are easy to grasp.  He is a scientist, but he writes like a novelist.  

I do not have any photographs to share here but check out the book's Facebook page.  I hope the page will be updated with a "who's who" of Cape Cod conservation.

Our most abundant and widespread dove


Although the pigeon is in the Dove family and is also known as the rock dove (Columba livia), this post is not about that city bird.  Rather it is about the mourning dove or Zenaida macroura.  The Field Guide to the Birds of North America (1987, Third Edition) is the source of the quote that titles this essay. 


The Mourning Dove's most distinctive field mark is its "pointed tail bordered with large white spots" writes Peterson in A Field Guide to Western Birds (1961).  Otherwise is habitat and nest are ordinary.  "Farmland, towns, open woods, mesquite, coastal scrub, grassland, and desert" lists Peterson.  The Cornell Lab of Ornithology lists "open country, scattered trees, woodland edges, ... [and] woodlots during winter."  Its nest is not much to speak of according to Peterson's description: "[a] flimsy twig platform in tree, shrub, cactus, or on the ground."  We thought the nest we saw in a nearby garden had been vandalised but not so after reading Peterson's entry.

Recently we saw a Mourning Dove pecking on the ground.  We thought for ants or other crawlers but a check with American Wildlife & Plants: A Guide to Wildlife Food Habits (Martin, Zim, Nelson, 1951) revealed that the Mourning Dove only eats "traces of insect or other animal food."  The entry at Cornell's All About Birds notes that the bird "sometimes eat[s] snails."

Book Review: Public Produce by Darrin Nordahl

We have been foraging the ripe Juneberries in our neighborhood.  The birds have been eaten the berries, too.  Also, the Juneberry or Amelanchier spp. provides an understated beauty to the streets and pathways it lines.  Contrast our story with the one presented by Darrin Nordahl on page two of Public Produce: The New Urban Agriculture (2009):
Perhaps we were caught unawares because, even in our nation's capital, where more than three-thousand iconic cherry trees have become one of the city's premier tourist attractions, we are accustomed to plants in the urban environment providing simple aesthetics, rather than whole nourishment.  The Kwanzan cherry, the specific variety that makes up the bulk of the cherry trees in East Potomac Park, is a fruitless cultivar.  The Yoshino cherry--the principal cultivar that encircles the Tidal Basin and punctuates the Washington Monument grounds--does produce fruit, though it is stony and unpalatable to all but birds.  There is no denying the poetic beauty of these trees--a generous gift from Japan--whose showy blossoms are an allegory of friendship.  Yet, I wonder, if flowers can be an accepted symbol of goodwill and inspire all who gaze upon them, can fruit become an accepted symbol of equity, for all to eat?
Kwanzan cherries, Bleecker Street, NYC
 Our neighborhood is not filled with human-edible trees; the Amelanchiers are the exception not the rule. Furthermore, many of them are growing on private property though overhanging public rights of way.

Nordahl argues for public fruit because we live in food insecure environments, especially urban dwellers.  In Chapter 1 of the book, he defines several contributing factors of food insecurity: agricultural specialization, fossil fuel reliance, water scarcity, weather anomalies and climate change, food contamination (from agri-chemicals, bacteria and other pathogens, and bio-terrorism), and inaccessible and unaffordable food.  To combat these factors, to make food accessible, affordable, and secure, Nordahl proposes a  system of "fresh produce grown on public land, and thus available to all members of the public --for gathering or gleaning, for purchase or trade" (page 4).  But such places exist already you might say in the form of community gardens.  Nordahl argues that the conventional community garden while operating on publicly owned land is "maintained as if [it] was private" (page 89).

In Chapters 2, 3, 4, and 5, Nordahl describes the challenges to a public produce model.  Among them are land use policy, maintenance and aesthetic objections, and food illiteracy.  He also offers solutions, mostly cases of elected officials, planners and policymakers, and designers who have implemented "public produce" projects.  The Chicago City Hall apiary is an example.  Nordahl tells us in 2003 then Mayor Daley invited two beekeepers to construct and manage an apiary on City Hall's green roof.  The bees produce two seasonal honeys which are sold throughout Chicago and via the internet.  (I could not find price information.)  Nordahl offers this case as an example of the strong role an elected official can play in food production on public land.

Foraging olives, Berkeley
Back on the ground, Nordahl looks at public policy in three Western cities.  San Francisco and Berkeley do not permit the planting of fruit trees in the public right of way while the City of Portland, Oregon at the time of the writing of the book was "seeking to codify the acceptance of fruit trees for their use as street trees" (page 54).  (By the way, we foraged from many fruit trees growing in the sidewalks when we lived in Berkeley.)

One of the excellent contributions of this book is Nordahl's discussion of maintenance and aesthetic objections to (permitted) fruit tree planting in the public right of way.  It is one that we heard from citizens and public officials and staff in most of the cities in which we have lived.  People argue that food-bearing trees and edible gardens are "messy and difficult to maintain....a bit unkempt, or...downright ugly" (page 91).  Nordahl counters these objections with three simple concepts.  First, to address messiness and litter, plan for the appropriate carrying capacity, i.e. match "expected crop yields to numbers of people likely to harvest the produce" (page 99).  Additional steps could include organizing volunteers to harvest produce and partnering with nonprofits to donate the harvest to food banks.  Second, use existing resources and policies to minimize maintenance requirements.  Since parks and recreation staff maintain ornamental plants in spaces wherein edibles be grown, the maintenance burden is less significant than presumed.  Also, the maintenance of vegetation in public rights of way is usually assigned to the adjacent property owner so a fruit tree in a sidewalk would be maintained by the property owner who is most likely to have planted the tree.  Nordahl underscores the maintenance difference between woody perennials and herbaceous annuals, arguing that the former "only need care and supplemental water for the first year to get established" (page 108).  And the third counter to maintenance and aesthetics objections is designing "edible landscape[s] imbued with artistry and beauty" (page 111).

A central challenge to Nordahl's public produce model is food illiteracy.  He writes,
As social creatures, we learn from others and from our environment, and what we learn is what we see....Lately our ancestors have not passed along the culture of growing food or of preparing and eating what we are able to raise in our particular environment....Before we can incorporate better food into our communities, we have to incorporate better food into our vocabulary.  Better food choices need to be taught throughout our communities, and public space could become educational in this regard (page 117).
So what does a food literacy campaign look like?  Government should take the lead.  And the campaign could rely on the media used for the war garden campaigns as well as contemporary technology such as instructional web-based videos and public access television programs.  Nordahl also proposes including instructional brochures with utility bills and offering classes through parks departments.  Food literacy should be offered in schools, too.  "Food literacy, like language, is most effective when it is taught at a young age, and many experts say that food and dietary choices taught early in life set lifelong patterns," writes Nordahl (page 129).  Non-governmental organizations also have a role in providing food literacy programs.  Take Fallen Fruit in Los Angeles, a nonprofit that creates and publishes on its website maps of publicly accessible fruit trees throughout that city.  Two final notes on food literacy.  The rights and responsibilities of growers and eaters should be clearly written and posted.  Lastly, context is important in designing an edible landscape.  Nordahl generalizes that "[f]emale ginkgo trees may be unwelcome in predominantly white suburbs in America.  Callalloo would likely be regarded as  a weed.  Prickly pear may be more acceptable" (page 127).

Nordahl concludes Public Produce with a vision of a "comprehensive network of public produce," an amalgamation of the cases he presents in the book.  The rehabilitation garden for former offenders run by a sheriff in San Francisco, the city hall rooftop honey in Chicago, the vegetable garden grown by a parking lot manager in Davenport (Iowa), fruit trees in Portland (Oregon) and Des Moines (Iowa) parks planted by parks department staff, the one community garden per 2,500 households mandate in Seattle's comprehensive plan, fruit tree maps in Los Angeles, and foraged fruit for meals trade in Berkeley.

What does urban agriculture look like where you live?

Woolly Pockets in Washington Square Park


Another reason to love Washington Square Park is the Woolly Pocket planters in the renovated playground.  (The latter is the subject of a future post.)  I think the Woolly product used in the playground is a School Garden and not a Wally.  Woolly Pocket also makes the Meadow and Islands.  A web search revealed that City-as Farmer planted tomato, okra, carrot, and other vegetables on Sunday, May 15, 2011. 


I wonder who will care for this garden?  Who is allowed to harvest the produce?

This is not the first use of a Woolly Pocket product in a park.  wrote about the garden installed at William F. Passannante Ballfield at Houston and Sixth Avenue during the summer of 2010.

Have you read our post about the filming of a Sesame Street segment in the park?

Bird Watch: Top 10 methods for studying birds

Mourning dove in nest

Writing for BirdScope (Vol. 25, 2), Laura Erickson listed the "top ten technologies for studying birds" as:

1. Field guides and binoculars
2. Numbered leg bands
3. Cameras
4. Microphones and recorders
5. Radio and satellite transmitters
6. Radar
7. Spectrograms
8. DNA analysis
9. Telecommunications
10. Autonomous recording units or ARUs

(See the Washington Square Park Blog via Urban Hawks blog for a map of Bobby's "haunts")
We have used several of these technologies: field guides and binoculars (#1), cameras (#3), and telecommunications (#9). Most recently, we have been following the "hawk cam" of the red-tailed hawks nesting on the Bobst Library on West 4th Street. The New York Times published an excellent hawk resource list on June 3.  When we photographs birds or nests, we verify our sightings with field guides or with online resources like the Celebrate Urban Birds project.

To Laura's list I would add natural history books such as Crow Planet (which was reviewed by Metropolitan Field Guide), Pigeons, and Red-Tails in Love.

Which of these methods do you use regularly and which ones would you like to try?  You can follow more of Laura Erickson's writing at Laura's Birding Blog.

Sesame Street in Washington Square Park


There are so many reasons we love our neighborhood Washington Square Park.  The filming of a Sesame Street segment this morning is one of them! 


*Spoiler alert*
Murray Monster and Rosita counted to five in Spanish (Rosita teaches Spanish words) and cookies popped out of a hat.

Chelsea Flower Show 2011 gardens


We did not attend the Chelsea Flower Show but we know someone who did and she shared photographs of seven of the 17 gardens at the flower show (thank you).  The descriptions below are taken from the BBC - Chelsea Flower Show 2011 website.


The Irish Sky Garden by Diarmuid Gavin won a Gold medal & the RHS People's Choice Award.
Beneath the suspended pod, which is covered in living grass, a myriad of dark pools reflect what's happening above. Large hornbeams point up to the sky and soft mounds of box and pine create cloud-like shapes amongst the pools. A ribbon of rusted steel cuts across the pools leading you up to the sky garden. Once aboard and up in the sky there are views of the showground which have never been seen before.
The list of plants include:

Miscanthus sinensis
Photinia x fraseri 'Red Robin' - Christmas berry 'Red Robin'
Carpinus betulus - hornbeam
Buxus sempervirens - box
Argyranthemum frutescens - marguerite
Lavandula angustifolia 'Hidcote' - English lavender 'Hidcote'
Carex comans 'Frosted Curls' - sedge 'frosted curls'


The Laurent-Perrier Garden - Nature & Human Intervention by Luciano Giubbilei also won a Gold medal. The design, notes the BBC,
plays with the notion of how nature and human design coexist in a garden. At the front of the garden floriferous and romantic borders run along either side of a long pool. Planted with pink, maroon and brown flowers the borders are softened by the hazy flower heads of Deschampsia cespitosa....At the rear of the garden is a more reflective, quiet area with a pavilion by Kengo Kuma and sculpture by Peter Randall-Page.
This garden is landscaped with the following plants:

Parrotia persica - Persian ironwood
Pinus mugo - dwarf mountain pine
Digitalis x mertonensis - strawberry foxglove
Deschampsia cespitosa - tufted hair grass
Carpinus betulus - hornbeam
Iris 'Dutch Chocolate'


Another Gold medal garden is A Monaco Garden by Sarah Eberle.
The structures at the rear of the garden evoke the architecture of Monaco and it's high-rise living. From these buildings a cantilevered green roof floats, filled with lavender, its the perfect place to escape the Mediterranean sun. A space-saving green wall reminds us that Monaco is framed by huge cliffs cloaked in plants like Carpobrotus and Osteospermums.
The complete description can be read here. Did you know that the chocolate substitute carob grows on a tree? Caratonia siliqua is on A Monaco Garden's plant list along with these:

Pinus nigra - Austrian pine
Carpobrotus edulis - Hottentot fig
Lampranthus (different varieties)
Osteospermum - different varieties
Chorisia speciosa - floss silk tree
Aloe barberae (Syn. Aloe bainesii) - tree aloe
Citrus reticulata - Mandarin Orange


Probably our favorite garden - based on the photographs we received - is the Tourism Malaysia Garden by James Wong and David Cubero.  It's a Gold medal garden, too.  We thoroughly enjoyed our visit to Malaysia a few years ago.  The Wong Cubero garden is based on Malaysia house design:
In Malaysia temperatures and humidity can become intense, so many houses have internal courtyards which use water and lush planting to create a cool oasis. James Wong and David Cubero have designed their own Malaysian courtyard using modern materials, contemporary design and tropical plants.

The long list of plants can be read here.


And the best of show (and a Gold medal, too) is The Daily Telegraph Garden by Cleve West. Here is entire description of the garden by the BBC, including the designer's inspiration:
This Best in Show garden may at first glance look like an excavated Roman ruin; large column sculptures which are repeated through the design. One, lying on the ground, looks as if it has fallen giving the garden a sense of time passed.

Playing with this idea of time elapsing Cleve has also used plants which self-seed and has placed them as if they've drifted around the garden on a breeze filling the earthy tones of the hard landscaping with accents of yellow from parsnips grown on Cleve's own allotment and red from Dianthus cruentus.

The garden is surrounded by a backdrop of Taxus baccata (yew) and specimen trees of Styphnolobium japonicum (the Japanese pagoda tree), rise up from the sunken gravel area and soften the impact of the columns.
Inspiration / influences

Cleve: The garden was "partly inspired, subconsciously, by a trip I made to Libya where I saw the... Roman ruins of Ptolemais". You wouldn't find a garden like this in Libya or the plants either, but it's a personal garden and Cleve believes that "If you don't create it from the heart, then it's very difficult to do a good job."
Here are the plants found in this Libyan-inspired garden:

Styphnolobium japonicum - Japanese pagoda tree
Taxus baccata - yew
Buxus sempervirens - box
Acaena microphylla - New Zealand bur
Pastinaca sativa - parsnip
Dianthus cruentus - blood pink
Erigeron karvinskianus - Mexican fleabane


Last here is the B&Q Garden by Laurie Chetwood and Patrick Collins (another Gold winner) which features an insect hotel, above. The B&Q is
the tallest garden ever built at Chelsea thanks to the nine meter glass tower covered in plants which rises above a glass banqueting table. The planting on the tower is achieved using two methods, on one side a collection of window boxes hang filled with large crops like tomatoes, peppers and edible flowers, on another, a hydroponic living wall is full of culinary herbs....Mirroring the tower is an insect hotel, filled with boxes of insect habitats and materials for wildlife to nest in and use. The individual boxes were made by school children and put together to create a colourful and useful display.
Lavender, mulberry, rose, and linden or lime are among the plants; the full list is available here.  The insect hotel concept is a popular habitat strategy in wildlife studies and design.  Read the following pages at the Metropolitan Field Guide: Beyond the Hive Results and Insect hotels, mansions and other dwellings. Also see the Animal Architecture blog.

GirlAboutGarden attended the show and has lots more photos than we do.  Read her show posts: Chelsea Flower Show 2011 – Press Day Highlights and Chelsea Flower Show 2011 – In Pictures.

Hideo Sasaki's Garden in Washington Square Village

Bosquet of crabapples (original to the design) Japanese maples (later addition)
Landscape architect Hideo Sasaki's interdisciplinary approach to landscape design was well known and regarded.  The work of Sasaki and his firm "display[ed] exceptional harmony of architecture, landscape architecture and art," writes The Cultural Landscape Foundation.  Sasaki's studies at UC Berkeley in the 1940s were interrupted by an internment at the Poston War Relocation Center during World War II.  He later completed his landscape architecture studies at the University of Illinois and the Harvard Graduate School of Design.  Sasaki completed significant projects in the U.S. and one of his most famous landscapes in New York City is Greenacre Park.  Lists of his projects can be found here and here.  (The Sasaki firm now operates as Sasaki Associates, Inc.)

Trellis replaced in spring 2011; new bench
Sasaki designed another landscape in the city: the modernist 1.5 acre Garden for Washington Square Village (WSV).  The WSV complex of "1,292 apartments in two parallel tower slabs of two buildings each, enclosing a park over a 650-car underground garage" was opened in 1958. The buildings were purchased in 1964 by New York University (NYU) for faculty housing.  The WSV Garden, completed in 1959, is located between the two mid-rises.  Photographs of the site before and just after construction can be viewed in a wonderful report titled WSV Garden Rehabilitation Plan by Ellen Jouret-Epstein. The document also contains a thorough site history.


In its controversial NYU 2031 plan, the university proposes to eliminate the garden in order to build "two academic buildings and below-grade academic space" according to the NYU 2031 North Block Site Plan overview.  The residential courtyard atmosphere would be lost, replaced by a social quad for college students.  The plan also calls for "a single accessible open space" that can accommodate a range of uses such as "quiet contempla[tion]" to "active play."  (The latter is included because The Plan calls for the eventual elimination of a 20,000-plus square foot playground known as the NYU Key Park, open to NYU affiliates and community members within the NYU "catchment area."  (See pages 146-147 of Chapter 6 (The Core) of NYU 2031.))

Platforms (note the globe standards)
We are regular users of the Sasaki-designed garden and even more now, knowing of its (proposed) fate.  It holds so much of interest for adults and children: water (fountain); shade and sun; places to sit and to climb; birds, ants, squirrels, and other wildlife; a seasonal palette of vegetation; other adults and children; and open and refuge areas.

Fountain (originally ten jets, now only one)
The WSV Garden is a privately owned public open space is elevated because of the garage below.  It is accessible by several staircases and one ramp.  Because the garden is not at grade, passersby are deterred from using it.  It "reads" private.  There are no signs that encourage entering the garden.  But it is well used by those those who know its public nature.  It is a "nature-ful" alternative to area playgrounds.  Recently, I saw two older children teaching a younger child to swing from a tree branch.  (This type of behavior is prohibited in the garden, we learned recently, as the parent of a couple of the swinging children had a heated exchange with a staff person.)

Visit the garden!  And if you have photographs, share them at the local ecologist Facebook page, thank you.
