Our surroundings have the power to shape our emotions, health, and well-being. We can feel this in our bodies – our tensions heighten while driving in city traffic, and relax while walking in a park – and research supports it, too. The lights, sounds, and colors of the environment in which we live and work… More
When we talk about the value of urban trees and soils as a stormwater management tool, the contribution of the trees is often considered secondary. Soil will, of course, store significant amounts of runoff all on its own. However, new research at the Morton Arboretum in Lisle, IL, has found that trees actually provided the largest… More
If you are a regular reader of this blog, then you know we’ve had a recent spate of articles about biochard – from its history, to a discussion of possible applications and controversies, to a question-and-answer following a recent webinar about what designers need to know about the product. Because of the tremendous potential for… More
In previous blog posts we discussed the history of biochar, we offered our thoughts on its possible application, and examined potential controversies. Most recently, we interviewed Kelby Fite about his work with biochar and held a webinar to discuss what designers need to know about the product. The following post is a collection of questions… More
Today I had the privilege of talking to Austin Troy, Professor and Chair of the Department of Planning and Design at the University of Colorado Denver.

“Right tree, right place” is easier to do in Ohio thanks to the Urban Site Index (USI), a tool for assessing soils and planting sites developed by OHDNR regional urban foresters Alan Siewert and Stephanie Miller. By observing various tree species in various sites, site ratings for different tree species can be developed for various… More

We have long known that urban trees help mitigate air pollution. But what about questions of how significant that mitigation is, how we track it, and where it occurs? A 2014 paper, “Assessing the relationship among urban trees, nitrogen dioxide, and respiratory health” by Linda George, Meenkashi Rao, Todd Rosenstiel, Vivek Shandas, and Alexis Dinno… More
Unmanned Aerial Vehicles (UAVS) – aka drones – are all over the news. As they get lighter and more affordable, the applications for their use widen. Brian Ritter, an ISA Certified Arborist, Registered Forester, and current PhD candidate in Forest Resources at Clemson University, studied their applications in urban forest inventories, summarizing his research in… More
