My bedroom abutted the lush, tangled backyard, which had had grass once but had been overtaken by errant ice plant and other, native coastal scrub and weeds. A cypress stood untrimmed in the corner of the yard and ivy crawled up the side of a dead oak that stood tall and stately and truncated just at the level where the first branches might have begun. The grass was tall and impassible, and the overall state of the yard made me uncomfortable. It was a mess to be put into order, like the living room and the bathroom and the hall, but yard work presented a challenge that cleaning the house did not.
I asked Russell one day why he didn't do anything with the backyard. He shrugged and said it was a rental house. "And anyway," he said, "look out the window sometime, and tell me if you think what you see would feel quite as comfortable in a yard with a manicured lawn and trimmed oleander."
I didn't think much about what he meant until an evening two or three days into March when I heard a scratching sound outside my window and sat up in bed to see a spotted skunk digging for slugs by the waning moon. The backyard wildlife had been an idle preoccupation that I didn't think much about unless it was bedtime, and I could spend an hour on my knees on the bed, leaning on the windowsill and waiting for a barn owl or a raccoon to visit in the night.
When I presented my first discovery, he told me about ecosystems, and the next time we went to the beach, he went on about it some more. The whales and dolphins and sea lions out there in the ocean fed on the fish, check out the pelicans, Hazel, and I learned more about mercury and sand and seaweed than I thought there was to know. He pulled a drawer out of his desk and showed me a sheet of kelp forest stamps. It was a self-contained ecosystem, and while his backyard was only a tiny patch of Daly City, it was the home or on the route of several different kinds of native species. "If you want to do anything to it," he said, "pull up that ice plant. It's invasive. It was planted here a hundred and fifty years ago to keep the cliffs from falling into the sea, and it's taken over everything." Like cottontails and starlings and house cats and angry-looking house sparrows. I was not so much interested in the diversity of the animal life, but the idea that those animals could make a living on slugs and forage was fascinating. I wondered what it would be like to pry mussels from a rock with a screwdriver for your lunch or dive for seaweed and abalone in the cold Pacific ocean.
