CALIFORNIA WON’T BE throwing much shade this summer. It would need trees to do that. Last year almost 30 million trees died in the Golden State—and that number is expected to double or triple by the end of 2016. The high mortality rates come at a time when the state needs healthy forests most, with climate change looming always and a La Niña—El Niño’s dry hermana—on the way. — Wired

We all want our cities to be greener, but it is often quite hard to grow trees in a concrete environment. So, why not turn to waterfronts or lakes to place trees? Rotterdam will get its first ‘bobbing forest’ in 2016: a collection of twenty trees that are floating in the Rijnhaven, a downtown harbor basin. [...]

After experimenting with a sample tree last year, an entire floating forest of twenty trees is scheduled to be ‘planted’ on March 16, 2016. — popupcity.net

Completed in March of 2014, Kusukusu [...] is a marvelous feat of architecture, engineering and technology. Working with Hiroshi Nakamura of NAP Architects, the team came in and 3D-scanned hundreds of points on the tree. Based on that 3D data they then created a steel trellis that threaded through the tree, interlocking perfectly [...]. What’s amazing is that the treehouse in its entirety, never touches the tree. It’s completely self-standing so as to not harm the tree. — spoon-tamago.com

You don’t have to be religious to appreciate the Tree Church in Ohaupo, New Zealand. A heavenly 100-seat chapel set among a 3-acre landscaped garden, the church boasts walls made of living trees planted around an iron frame. In 2011, Barry Cox, who runs a tree relocating business, decided that his backyard was missing an old stone church like the ones he had studied and admired on travels to Europe. — Slate

The city of Melbourne assigned trees email addresses so citizens could report problems. Instead, people wrote thousands of love letters to their favorite trees. — theatlantic.com

In a new paper published Thursday, a team of researchers present a compelling case for why urban neighborhoods filled with trees are better for your physical health.

[...] they found that “having 10 more trees in a city block, on average, improves health perception in ways comparable to an increase in annual personal income of $10,000 and moving to a neighborhood with $10,000 higher median income or being 7 years younger.” — washingtonpost.com

To be recognized as a Great Tree, in New York City, is not just a matter of having the correct heritage or coming from the right family. [...]

For a person, achieving fame or prominence comes with both perks and pitfalls. But what are the advantages of being a celebrated tree? And what are the dangers? While humans have long venerated old and large trees, we've also cut them down and razed whole forests of their less superlative brethren. — atlasobscura.com

Though New York can sometimes seem like a drab warren of chain-link fence and oily pavement, the city actually has an impressive number of trees. On the streets alone [...] there were 592,130 at last reckoning, a leafy explosion you can now peruse in this great visualization of tree species.

The city estimates that some 4,500 of its total 10,750 sidewalk miles are in disrepair. According to a 2007 USC study, the city repaired a grand total of 64 miles of sidewalks, or 1.4 percent of damaged sidewalks, improving the city’s backlog to 72 years.

The reasons for this civic embarrassment go back even longer than 72 years. They are twofold. One is political, the other arboreal. — nextcity.org

Want to make a skyscraper look trendy and sustainable? Put a tree on it. Or better yet, dozens. Many high-concept skyscraper proposals are festooned with trees. On the rooftop, on terraces, in nooks and crannies, on absurdly large balconies. Basically anywhere horizontal and high off the ground. — slate.com

A REVOLUTION in cognitive neuroscience is changing the kinds of experiments that scientists conduct, the kinds of questions economists ask and, increasingly, the ways that architects, landscape architects and urban designers shape our built environment.

This revolution reveals that thought is less transparent to the thinker than it appears and that the mind is less rational than we believe and more associative than we know. — nytimes.com
