The need for natural light, part II (and to be continued)
December 22, 2008
In researching for this blog posting on the need for natural light, I’ve uncovered so much good information that I wouldn’t be able to do the subject justice to try to write about it today, when I’m crunched for time. So, stay tuned while I do a little more digging and collecting thoughts.

Nature-Deficit Disorder: Getting Kids Outdoors (watch the video clip!)
December 3, 2008
Here’s a nice television clip from CBS and wjz.com about Nature-Deficit Disorder (a term coined by Richard Louv of Last Child in the Woods and the Children & Nature Network). My favorite part is when TV anchor Don Shelby asks kids what “nature” means to them. You can either watch the clip (after a brief but nonetheless annoying advertisement) or just read the transcript. I’ve blogged about Louv before, so if you’re new and you want more, use “Louv” in a keyword search in the column to the right to pull up all relevant posts.
You can watch more news clips and get lots more great information about children and nature on the C&NN website.
And here are two more good related articles that I’ve come across recently:
“Research Shows a Walk in the Park Improves Attention in Children with ADHD,” by Frances E. Kuo and Andrea Faber Taylor, 2008. Click HERE to read the University of Illinois at Urbana-Champaign press release.
Amount of green space and childhood obesity:
“Neighborhood Greenness and 2-Year Changes in Body Mass Index of Children and Youth,” by Jeffrey Wilson and Gilbert Liu, 2008, American Journal of Preventive Medicine, Vol. 35 No. 6.
Summary by Research Design Connections: “The amount of green space near their homes is related to the weights of inner city children. Children living in inner city neighborhoods with more green space (as determined from analysis of satellite photographs) have significantly lower body mass index changes as they grow taller than children living in areas with smaller amounts of green space.”

Leaves! Raking for Health (yours and your garden’s)
November 19, 2008
It’s getting cold here in the Hudson Valley (23 degrees this morning) and it’s really starting to feel like winter. The weather has been not only cold but rainy for the past few days, so I didn’t mind this morning because it was bright and sunny – a good day to tackle a chore I’d been putting off for weeks – raking leaves. As a child, this was one of my favorite activities (well actually, “helping” my parents rake and then jumping into the piles of leaves on my hoppity-horse). Now, I tend to dread it, despite the fact that I usually feel good after. In general, I enjoy putting the garden to bed for the winter. Cleaning up, deadheading (though I always leave some seedheads for the birds and for “decoration” – they look beautiful in winter, especially poking out from a blanket of snow with little snow-hats of their own), mulching, and dreaming of next year’s garden. Raking is a big part of that. And it’s good exercise!
An article in Martha Stewart Living from way back in March 2007 (“Reap the Benefits of Gardening,” by Peter Jaret) discusses the psychological and physical health benefits of gardening. Raking is one of many gardening activities that, if done for 30 minutes a day, can increase metabolic rate, reduce blood pressure, improve cholesterol levels, tone muscles, improve flexibility, and even improve cardiovascular fitness – enough to reduce the risk of heart disease and type-2 diabetes. Gardening, including raking, burns between 265-415 calories per hour, depending on the level of activity (pushing a hand-mower or raking leaves will be more strenuous than light weeding; for comparison, jogging burns about 430 calories per hour). And that’s just the physical exercise. The psychological benefits of working outdoors are myriad (and, of course, they’re all connected anyway). Many horticultural therapy programs include raking; it’s something most of us have done at some point in our lives, and often brings back fond memories – in addition to the physical activity, the smell and sound of leaves is very evocative and can trigger positive memories and feelings – which is particularly important for people with dementia.
And if all that isn’t enough to make you want to grab a rake and go to it, remember that the old-school way of dealing with leaves is a lot better for the environment than standing behind a leaf-blower, using expensive gasoline, inhaling fumes and going deaf while enraging all of your neighbors in the process.
As with all garden work, take care not to overdo it by lifting too much, working more than you feel up to, or exposing yourself to the elements (sun, heat, wind, cold) for too long. The Martha Stewart Living article (link above) is chock-full of good information, including pointers on lessening the risk of strain or injury while you’re getting that good garden work-out.

“Responses to Scenes with Spreading, Rounded, and Conical Tree Forms.”
This study sought to understand reactions and preferences of 206 participants to different types of tree forms. It was predicted that people would have a preference for the savanna-like spreading form. Participants viewed slides of trees that were digitally enhanced to emphasize the conical, spreading, and rounded tree forms. Measurement tools included preference questions, affective responses, skin temperature, and blood pressure. Results revealed that the spreading form was preferred over rounded and conical forms. It was also important that any tree form was preferred over inanimate objects in an urban setting. Trees, regardless of their shape or canopy density, are essential in urban environments for the well-being of the residents.” Environment and Behavior, 12/20/2007, 5 667-688.
Sustainable Sites Initiative draft open for public comment
November 14, 2008
The Sustainable Sites Initiative invites public comment on the new report titled Guidelines and Performance Benchmarks Draft 2008, the most comprehensive set of national guidelines yet developed for the sustainable design, construction and maintenance of landscapes. The report is available for download at www.sustainablesites.org, and an online feedback form has been created for users to help improve the guidelines.
These guidelines will enable built landscapes to support natural ecological functions by protecting existing ecosystems and regenerating ecological capacity where it has been lost. The report includes more than 50 prerequisites and credit options that cover everything from initial site selection to construction and maintenance. The report represents thousands of hours with input from 37 technical advisors in hydrology, vegetation, soils, materials and human health and well being. These credits were tailored to apply to any landscape, with our without buildings.
