The science of urban greening

For the last 18 months an intrepid and international group of urbanists, activists, and researchers has been meeting regularly to the...

Outbreaks of disease in the19th and early 20th century shaped the design of modern cities and parks.

Many new advances in greening science made their debut at the 2020 ESA annual meeting.

Lawn grasses, tree cultivars, and other ornamental plant "cultigens" are what most urban greenspace is made of.

The ecology of plants that have been hybridized or bred is far less studied than “naturally” occurring species.

I started this blog to chronicle urban greening issues around the world and made it as far as Australia before the pandemic crisis struck.

For one day during the bushfires, Penrith, NSW was declared the hottest place on the planet.

Greening isn't always the most effective solution to pressing urban problems. But that doesn't mean the problems can't be solved.

Does the call for more experimentation mean that green infrastructure still needs more testing than grey infrastructure?

After the Millennium drought, Australian cities found other ways to irrigate parks, gardens, and landscapes, and so can we.

With more high density and mixed-used buildings crowded into urban areas, where will all the trees go?

You don't just need expertise or experience to be an effective steward of urban trees. You need a network.

The catastrophic bushfires are a terrible reminder that adapting to climate change won't be enough. Here's how urban trees can help

American universities are still struggling to evaluate and reward practical, use-inspired, and community engaged research on solutions to...

Should arid cities plant more trees in a hotter and drier world? The science of “socioecohydrology” aims to find out.

At this site I'll be posting non-technical summaries of new projects in urban greening from my lab, my colleagues, and the people I'm meetin
