Phoenix broke several heat records last year. Now Grant Park, which has inequitable tree cover, is seeing a tree planting drive that promises some respite from 100F temperatures
It was a relatively cool spring day in Phoenix, Arizona, as a tree planting crew dug large holes in one of the desert city’s hottest and least shaded neighborhoods.
Still, it was sweaty backbreaking work as they carefully positioned, watered and staked a 10-ft tall Blue palo verde and Chilean mesquite in opposite corners of resident Ana Cordoba’s dusty unshaded backyard.
“If I ever retire, I’d like to be able to spend more time outside. The weather is changing, so I am really happy to get these trees. We need more shade,” said Cordoba, 75, a legal secretary, whose family has lived in Grant Park for more than a century.
Over the course of three days in early April, arborists planted 40 or so desert adapted trees in Grant Park, as part of the city’s equity-driven heat mitigation plan to create a shadier, more livable environment amid rising temperatures and hundreds of heat related deaths.
I’m not an expert but my understanding is desert trees are adapted to be tougher, retain moisture longer and flower/leaf based on rain patterns vs strictly following the season. Googling will bring up a bunch of results, here’s one.
Phoenix used to have a ton of trees, but the problem was they had planted varieties that were inappropriate for the climate. From this page I see the city has a plan to have 25% tree cover by 2030. You can also see some old time pictures of all their trees.
