Having started with the simplest ways to quantify stormwater benefits of Tree Stormwater Control Measures (SCMs), we now arrive at the most complex ways. Part 1 of this series provided an overview of various ways to quantify stormwater benefits of Tree Stormwater Control Measures (SCMs), and gave an overview of tree benefits calculators and stormwater… More
Russell Horsey is the Development Director at the Institute of Chartered Foresters in the United Kingdom. Prior to joining the Institute, Russell was Senior Arboricultural Officer (similar to Head Urban Forester in a U.S. city) for the City of Bristol, England. He is a graduate of the Universities of Brighton, UK, and gained a Masters… More
Richard Adkins, the Forestry Supervisor for the city of Phoenix, Arizona, likes to joke that despite the perception, Phoenix actually does have an Urban Forest. I met Richard when we were both speakers this past August at the American Public Works Association (APWA). He spoke to me about Phoenix’s current urban forest and some of… More
A natural forest depends on a variety of partnerships between plants, animals, fungi and micro-organisms. An urban forest depends on a similarly complex series of partnerships, albeit mostly between humans. Many biological factors affect the survival of an urban tree. I want to compare two studies involving community forestry programs about young urban tree establishment… More
In part one of this post, I gave my recommendations for how to address tree maintenance needs in a smarter and more financially (and ecologically) sustainable way. Those recommendations are great, but also general. I think we benefit the most when we share as much specific information about implementing ideas as possible, so today I… More
If you’re a municipal arborist, you probably got into the field of tree care because you love working with trees and you could make a modest living. You know that that in cities maintenance is the only way that trees get large – and that size matters when we talk about the kind of ecosystem… More
If you’re involved with an urban development project, chances are trees are also involved in some way, depending on the local municipal codes. Existing trees may need to be protected or require a permit for removal. Many municipal codes require a Certified Arborist to evaluate all or some of the trees on site and write… More
Trees have myriad positive effects on urban areas. And finally, forward-thinking cities are beginning to see trees as an important investment and understand that well cared for trees are not only an asset to the community, but can also save cities money. Many people already know that trees cool cities and reduce the heat island… More
Dr. Kelby Fite is a national leader in the use of biochar to improve tree health. Kelby is an Arboricultural Researcher at Bartlett Tree Laboratory in Charlotte, North Carolina — a 350 acre private arboretum, diagnostic laboratory, and exceptional applied research center. His specialties are root biology and urban soil renovation. Kelby has a PhD…. More
Imported soil specifications have evolved over the last 30 years to become quite specific about products. Frequently, they appear to be iron-clad descriptions of the most optimum soil; many specification writers would like us to think that even minor deviations from these documents will result in horticultural disasters. But “standard” specifications are not one-size-fits-all. Many… More
In 1982, I was in China studying landscape architecture and architecture at the University of Nanjing. The central Chinese government had recently announced they would recommit to a nationwide multi-billion tree planting program, originally initiated in 1978. By then the Cultural Revolution was over, Mao Zedong was dead, the Gang of 4 had been jailed, and… More
There is extensive evidence that soil is an amazing tool for improving the quality of water runoff, for reducing peak flow volume, and for storing water for use by the tree and for groundwater recharge in urban settings. We also know that trees in soil are basically “added capacity” – that is, while the soil… More
