Many people and (dare I say) authors of this blog cite energy savings as one of many benefits of healthy urban trees. But where exactly do these energy savings come from? The answer comes in two parts: trees benefit buildings immediately neighboring them, and they also benefit the surrounding city.
It has all but come and gone here in the upper Midwest, but the fall season makes living in this part of the world well worth it. Fall conjures up so many great feelings and memories. It is a time when you actually enjoy wearing wool socks and sweaters, get to plan Halloween festivities and… More
One of the most famous social science experiments of all time is the Stanford Marshmallow Experiment. This study, conducted in 1972 by psychologist Walter Mischel, examined the development of delayed gratification in children and the influence it had on their choices and success rates adults.
San Francisco non-profit Friends of the Urban Forest celebrated their 30 year anniversary last month. As part of their celebration, they recently revisited their first plantings (around 80 different sites) to see how they’re doing.
If you don’t already read Chuck Marohn’s blog, Strong Towns, I suggest you add it to the regular lineup.
Many readers of this blog may already be aware that the Environmental Protection Agency recently started a national rulemaking process with the goal of creating a new program to reduce stormwater runoff. To prepare for this process, they put out a request for information about projects utilizing green infrastructure design techniques that mimic natural stormwater processes (evapotranspiration, infiltration,… More
This EPA webinar was recommended to me by my colleague Sarah. She said Daniel Christian’s talk was a straight-forward overview of design and construction considerations and basics of green infrastructure.
Last weekend I went on a biking tour of the trees in the Mission District of San Francisco hosted by Friends of the Urban Forest and the SF Bike Coalition.
Last week Graham and I stopped by a Silva Cell installation as it was going in to the ground at Mitchell Library and Community Center (3700 Middlefield Road, Palo Alto, CA).
This hydrograph (diagram showing runoff flow versus time) compares the intense spike of a stream during a storm in an urbanized watershed without adequate controls, with the “gentle rolling hill” appearance of a forested watershed’s response to the same storm. Note the loss of dry weather base flow for the stream in the urbanized watershed…. More
I get several calls a week from the weekend warriors working on various home improvements. Often these improvements relate to cutting tree roots and some type of hardscape (such as sidewalks, driveways, foundations, and retaining walls). The first thing I suggest is that the homeowner talk to an ISA Certified Arborist before doing any sort… More
Here are this year’s photos from the Bartlett Tree Lab study comparing different planting methods for urban trees. For comparison, check out last year’s set. And for a fuller chronological picture, you can see all the photos up to that point in this post.
Soil. Stormwater. Sustainable Infrastructure.
