SF’s Biodiversity Corridor

Sunset Boulevard is a two-mile-long linear park running north-to-south that bisects San Francisco’s western neighborhood, the Sunset District. A six-lane thoroughfare, which tens of thousands of drivers, bikers, walkers and people on mass transit use daily, runs between 36th and 37th avenues.  

Humans aren’t the only organism who use this ecological corridor connecting Golden Gate Park in the north to Lake Merced in the south.  Ravens and crows, red-tailed hawks and gulls soar through the canopy of the Monterey Cypress and Pine. Down below, blue birds and finches search for food along the understory plantings of Coast Live Oak and Toyon. 

This busy thoroughfare is now approaching 90 years old and many of the larger trees are sinessing (dying) from old age as well as disease.  The Monterey Pine, for instance, is dying of pitch chancre, which is a fungal infection killing all but around 10 percent of the species. Many of the Monterey Cypress are beginning to fail from old age. 

Since 2018 CAN! has partnered with SFPW to raised State CalFire funding to support the community-led reforestation effort on 10 of the Boulevards 38 blocks.
