Re: Cities need more trees

Spent last week in South California, visiting family. Flying into LAX made me feel like I was flying into a hell scape. From the air, no green was visible for miles. Compared to my home (London, originally Manchester), I thought it not just odd but barely liveable. You could almost the heat off the concrete by looking at it from the air. Driving around as far south as Orange County for the next week I was happily surprised when I saw any indication of nature at all. Perhaps it’s just me and what I’m used to, but the only spot I visited that felt really relaxing was up around Griffith Observatory.

One of my biggest complains for American cities is the risk adversity with respect to trees. In SF, the city went in a rampage to prune and tear down trees (mostly ficus) because of the risk of the branches falling. There are lots of rules for where you can and can't plant trees based on road visibility, signage, electric cables etc. Result is that you have a lot of tree-less spaces in a city where basically anything…

For an opposing view, look at what happened during the freeze in Austin, Texas for an example of policies that allow for minimal tree pruning. It was a significant issue that caused the city an incredible amount of damage. Electric was shut down for days, cars were destroyed, houses had trees fall on them, etc. Might still be worth it, but an interesting data point nonetheless.

Center City Philadelphia has a series of squares fro green space and they are laid out in such a way that one can chart a course through the squares to navigate on foot.

Earlier quoted context omitted.

I also happen to live in such area. It's nice, but there are also downsides – solar roofs for example don't make sense here.

That's fair criticism, but perhaps it'd be much more effective to have a few but large solar farms outside the city, no?

Or a nuclear plant.

When I lived in Delhi, my home was near the ridge area of North Campus. Its a lush forest with shrubs, ferns, and subtropical hard trees with a few lakes. The temperature difference, the coolness in air and the vibe difference from the rest of the city was like night and day.

I also know this feeling! I think if more people knew did, they would be more supportive of urban green spaces. It's always remarkable to ride my bike through a paved residential area and then cut through this green alleyway-- the temperature and air is so fresh and feels 5 degrees cooler than the street.

Kind of an odd flex given how walkable San Francisco is, but the "risk adversity" is because people actually die. Last year, five people died from fallen trees in a single storm (two in the city).

On the other hand, trees cool down the area so having lot of them should lead to fewer heat-strokes. Last week we hit 95F in my area and I wouldn't be able to walk my dog if not for the trees.

"You cannot see the wood for trees"

I'd argue there is so much good that the tradeoff of trees killing a few humans is worth it.

The biological diversity that returns - birds, carbon soil. The air quality. Less chance that the heat will kill our senior citizens. Trees prevent floods.

From NotJustBikes channel, trees and bushes can be used to obscure road visibility, which naturally forces drivers to slow down at a curve, which makes streets safer for pedestrians (43k deaths a year in USA from cars)

> You can still see a stark difference between rich and poor neighbourhoods to this day based purely on tree cover. You can see that here in Sydney. The poorer Western Sydney suburbs have a noticeable lack of tree coverage when compared with the richer inner west, northern, and eastern suburbs. I don't know which direction cause and effect goes. It is plausible that affluent suburbs can afford to plant trees, but it…

Visit Canberra! We have a remarkable amount of trees, it’s beautiful.

Here in Utrecht the Netherlands they are trying to greenify the city to reduce heat stress during the hot months. They try to plant as much trees and plants as possible, they try not to mow grass often and let it grow, they encourage homes to remove tiled gardens and add green, they have programs to turn roofs into green roofs. I like it, the city feels nicer to life in. https://healthyurbanliving.utrecht.nl/fileadmi…

I live there as well, and while I'm sure it could be worse, it's nothing compared to Johannesburg. I would like to see much more green throughout the city. Hopefully they will keep up the trend.

Well they are still in transition. My street is next. They will plant quite a bit more trees and plant areas. Looking forward to them :)

We have the same issue in my city with respect to areas lacking trees.

The trees in the more affluent areas tend to be better maintained by property owners, and replacement trees are planted when trees are lost in ice and wind storms.

The city's forestry department is working on a long-term solution to this problem but it takes time to grow trees.
