Unmanned Aerial Vehicles (UAVs) or “drones” evoke a variety of responses from people ranging from anger over privacy invasion to awe over the new perspectives on our world. But like the Force, drones are merely tools that can be used for either the Dark Side or the Light. My interest in drones is related to... More
We spill a lot of ink on this blog on topics like policy, history, research, and opinion as they relate to green infrastructure. That’s great – and we’re going to keep doing it! – but where trees are concerned, sometimes it’s before and after photos that tell the most compelling story. Pictures document change in a... More

We’ve all taken shelter under a tree’s canopy during a storm, grateful for its ability to intercept rain. You may not realize this, but rainwater that passes through tree canopies is modified both volumetrically and chemically in processes that have been relatively well studied in forests. That modification, which encompasses several different components, is what... More
In anticipation of the American Society of Landscape Architects tradeshow later this week, today we’re highlighting an iconic tree planting project using suspended pavement – including archival photos and original section details – that took place in Denver in the early 1980s: the 16th Street Mall. -LM Denver has long been a place of significance in the...
