Nice to see sports teams like to be a little silly and break the “rules.”
While you were out living your normal life, working your normal job, a baby Tyrannosaurus Rex threw out the first pitch in San Diego on Wednesday. I’ll give you time to read that again and adjust to our new reality (per MLB):
This is such a great commentary from Kaid Benfield’s Blog about the importance of trees for urban health and well-being that I just had to share:
…[recently] I was approached by someone from an initiative called San Diego County Trees. The initiative is the urban forestry project of the Energy Center, and they have all sorts of information extolling the benefits of urban trees along with a crowdsourced inventory of street trees in San Diego.
You can even click on a specific tree and get detailed information on its species, size, and annual economic benefit to the community. San Diego County Trees invites its readers to add to the inventory with information on additional trees not presently counted.
If you’re interested in the subject of the community benefits of trees, you can get additional information from the websites of the National Arbor Day Foundation and the US Forest Service. Among the tidbits I learned on one or the other of those two sites are these:
The net cooling effect of a young, healthy tree is equivalent to ten room-size air conditioners operating 20 hours a day.
If you plant a tree today on the west side of your home, in 5 years your energy bills should be 3 percent less. In 15 years the savings will be nearly 12 percent.
One acre of forest absorbs six tons of carbon dioxide and puts out four tons of oxygen.
A number of studies have shown that real estate agents and home buyers assign between 10 and 23 percent of the value of a residence to the trees on the property.
Surgery patients who could see a grove of deciduous trees recuperated faster and required less pain-killing medicine than matched patients who viewed only brick walls.
In one study, stands of trees reduced particulates by 9 to 13 percent, and the amount of dust reaching the ground was 27 to 42 percent less under a stand of trees than in an open area.
Several years ago, walkability guru Dan Burden wrote a detailed monograph titled 22 Benefits of Urban Street Trees. Among other things, he calculated that “for a planting cost of $250-600 (includes first 3 years of maintenance) a single street tree returns over $90,000 of direct benefits (not including aesthetic, social and natural) in the lifetime of the tree.” Burden cites data finding that street trees create slower and more appropriate urban traffic speeds, increase customer traffic to businesses, and obviate increments of costly drainage infrastructure. In at least one recent study (reported after Burden’s analysis), trees were even found to be associated with reduced crime.
I think some of the most important benefits, though, are felt emotionally…
I am a huge proponent of urban trees for all of the reasons stated above, as well as the emotional and psychological benefits that Benfield goes into, but also including the creative and playful benefits of having trees around to swing on, climb, watch animals in, or just sit and ponder under.
Benfield also goes into how trees are often controversial in urban environments because they drop leaves and sticks, and potentially branches, on streets and houses. But to me that is part of living connected to one’s environment, even if it means raking some leaves out of places you’d rather they not be (it’s not like the tree is intentionally dropping them on your lawn).
What are your feelings about urban trees? Have you planted a tree or shrub in your neighborhood? What did you like, or not like, about the results? Let me know in the comments below.
