How? It's surprisingly simple. Turns out, demand for trees in neighborhoods behaves a lot like a luxury item, as opposed to a basic necessity.
Tim De Chant at The Per Square Mile blog wrote about research on this a couple of weeks ago. Then, he went out and found examples, using images from Google Earth.
Research published a few years ago shows a tight relationship between per capita income and forest cover.
...They found that for every 1 percent increase in per capita income, demand for forest cover increased by 1.76 percent. But when income dropped by the same amount, demand decreased by 1.26 percent. That’s a pretty tight correlation. The researchers reason that wealthier cities can afford more trees, both on private and public property. The well-to-do can afford larger lots, which in turn can support more trees. On the public side, cities with larger tax bases can afford to plant and maintain more trees.
The trouble, as De Chant points out, is that the disparity here is about more than aesthetics. It's about air quality, cooling effects in the summer, and documented impacts on stress, crime, and quality of life. It's also interesting because it seems to go against the stereotype of wealthy suburbs where all vegetation has been eliminated in favor of houses.
That's Houston's Fourth Ward above, and River Oaks neighborhood below. But De Chant found satellite examples all over the United States, as well as in South America and China.

After years of speculation and wrangling over his remains, Kennewick Man turns out to be closely related to contemporary, local Native Americans after all. Discovered near Kennewick, Wash., in 1996, the skeleton ended up in a tug of war between tribes in the pacific northwest who wanted to bury the remains, and scientists who wanted […]

The European Organization for Nuclear Research, or CERN, has been releasing portions of its research to the public for years. This week’s massive 300 terabyte dump of Large Hadron Collider (LHC) data is the biggest yet by a long shot — and it’s all out there, open source, free for the exploration.
You may not love Microsoft Word, but you’ve definitely used it. Other than being one of the most ubiquitous programs on the planet, it’s been the go-to word processing system for more than a quarter-century because it’s as basic as it gets. But occasionally, you’ve got assignments that beg for a lot more options than simple […]
Almost everyone has their smartphone in a case of one kind or another. Beyond simple protection, finding a case that can charge your phone on its own, but doesn’t feel like it’s also adding a couple pounds to the phone’s weight is the tricky part. Billed as the world’s thinnest battery case, the ThinCharge iPhone […]
