Contrary to recent actions taken by the Federal government, Washington D.C.’s local government has made unprecedented strides towards creating a cleaner, more sustainable future. The District of Columbia has recently emerged as an environmentally progressive leader and is actively working to reduce greenhouse gas emissions, support clean energy innovation, and focus on livability for all… More
When an urban site is developed, existing mature trees are often removed to facilitate construction. After the building is up, “replacement” trees are often planted, depending on local ordinances. Will these trees actually make up for what is lost? Certainly not at first. Studies show that trees can take 26 to 40 years to become… More
Trees can do a lot of amazing things, but they can’t move away when the climate becomes inhospitable. Some can adapt to changing climate, and some can’t. Which species will be hit the hardest? The most “vulnerable” species are those most susceptible to genetic degradation due to declining populations in the face of adverse environmental… More
Intrinsic to the success of cities and the quality of life they offer is how people move within them. For the past century, the car has been the central consideration in the design and planning of our urban areas. Increasingly, however, the car-dominated planning era is behind us, as city dwellers are more frequently walking,… More
When you work with trees for a living, it’s easy to feel good about your impact on the environment. After all, trees provide us so many benefits including controlling stormwater runoff, reducing urban temperatures and sequestering carbon. However, there is a carbon footprint involved in their production, planting, pruning and ultimate removal. Trees play the… More
Cities are generally both warmer and more polluted than non-urban areas, as paved surfaces absorb heat, leading to increased energy consumption, and vehicle and human activity produces waste and airborne particulate matter. These have huge negative consequences for human health, but a dense urban tree canopy can help reduce these risks. The role trees play… More
Today’s landscapes are asked to perform much more than functional or aesthetic services: they filter and reduce stormwater runoff, provide wildlife habitat, reduce energy consumption, improve human health, and more. As projects become more complex, and clients aim higher to meet today’s climate challenges, the use of performance metrics is becoming increasingly prevalent.
This post is the third in a series of three sharing findings from research conducted on 10 Silva Cell projects across North America. Read part one about study design here and part two about our initial findings here. We’ve already shared some of the initial findings from this study in earlier posts. Today, we’ll discuss… More
This post is the second in a series of three sharing findings from research conducted on 10 Silva Cell projects across North America. Read part one, where we discuss the study design, data collection, and raw growth results, here. After designing the study and selecting the Silva Cell projects, we had to decide what performance… More
In order to document the growth and performance of trees in Silva Cells, and to validate our own approach to designing for both trees alone and trees-and-stormwater in combination, in 2015 we undertook a research and monitoring study of 10 Silva Cell projects across North America. This was a big project, as you might imagine…. More
