The shady politics of urban greening


Glare alone creates the long shadows of Los Angeles. So squinting was inevitable when the city announced the appointment of arborist Rachel Malarich as its “first-ever” forest officer. According to the announcement by Mayor Eric Garcetti, as part of the administration’s Green New Deal, the new forest officer will plant 90,000 new trees in two years. These in turn are expected to provide 61 million square feet of shade in underserved areas.

Glare defines Los Angeles. So squinting was inevitable when the city announced the appointment of arborist Rachel Malarich as its “first-ever” forest officer. Her job, part of the city’s Green New Deal, is to plant 90,000 trees in the next two years. Creation of an estimated 61.3 million square feet of new shade in tree-poor communities is to be done just as the city weans itself from half of its imported water, with a lion’s share of …

The mayor’s record on water conservation

The water conservation achievements of LA's outgoing mayor have been the subject of hyperbole, however there have been impressive savings. Since 2007, water consumption in the City of Angeles has dropped by 17.58%.

Aroused by rain

The appearance of this mushroom after a much-needed rain in the Los Angeles foothills demanded that I Find The Camera. In the interim between putting the photo on Facebook this morning with a request for an ID and getting a response to an e-mailed query from Los Angeles County Natural History Museum mycologist Florence Nishida this evening, speculation as to its genus involved unbridled merriment. Southern California resident treasure, memoirist Erika Schickel, ventured that it was a Micropenisula shlongaeria. My own suspicion had been a Phallus anthonyweinerii. After more ribald speculation and some genuine mycological story-telling on the social network, Nishida’s response by e-mail in early evening had a “eureka” quality.

You are a lucky girl,” she wrote, “nature has gifted you with a stinkhorn, aka phalloid fungus. It’s probably Lysurus borealis, though another species is very common in southern California, Lysurus mokusin. Just looking at your

Water quality beneath the asphalt

Those wondering why so much of the recent rain across Los Angeles was flushed out to the Pacific through a storm drain system instead of socked into the local aquifer will find part of a complicated answer in a fact sheet issued last week by the US Geological Survey. Run-off from the Transverse Ranges into the San Fernando and San Gabriel valleys hits land that the USGS classes as 83% urban, which means largely paved and impermeable. (For how a combination of arrogance and greed led to over-building of the Los Angeles flood plain, there is no better source than historian Jared Orsi’s “Hazardous Metropolis.”) Another  limit on our ability to store mountain run-off  in these valleys is groundwater pollution brought by that urbanization. The map below shows solvent hot spots. 

Hat tip to the Water Education Foundation’s Aquafornia for signalling the sheet’s publication.
