Spring in the Sutro Forest is lovely.
Where the canopy is largely unbroken, the sunlight streams through the trees with the filtered light particular to forests. Last week, flowers bloomed in the lower reaches of the mountain: the pinkish-purple Robert Geranium, some tiny fairy bells (Disporum smithi) hidden under their leaves; some fringe-cups; some brilliant nasturtiums peeking out; yellow-orange abutilons. The trails were dry then, though a couple of foggy nights since may have damped them down again.
We started our walk in the forest from Stanyan and 17th, the “Kill-Trees Trail.” It’s a good trail; it provides easier access to the forest from its east side – where street parking is available. And it’s a beautiful part of this woodland.
But while the trail-building elsewhere in the forest required no tree-felling, here 50 large trees have been cut down. (Click on the picture below for a larger version; the white numbers are trees that have been cut down. Several more have been cut since.)
It’s changed the character of the forest. Houses are visible through the trees, and several huge old trees that once guarded the trail entrance are gone, and with them, the sudden magical transition from city to forest. Now it’s more gradual, with a view of houses across in Edgewood and Woodland Avenues, and into the nursery that’s been there for a couple of generations and was resplendent with Pride of Madeira. “They look Jurassic,” someone commented.
The canopy has been opened up, which has encouraged some flowering plants, particularly the Robert geranium, but also fringecups, elk clover – and poison oak.
The undergrowth has recovered from the weed-whacking it endured soon after the trail-building. The blackberry thickets have recovered; for some months, this area had been carpeted only with a shallow layer of Cape Ivy. There’s still ivy, climbing the columns of the trees and providing crucial habitat for the birds.
The best news is, the birds are back. For about a year, the forest has been uncharacteristically quiet; possibly a combination of the frequent disturbance and the understory destruction discouraged them. But last week, the forest was again bright with bird-sound.
