In my first opinions article, I suggested that students be permitted to “live with” art in their dorm rooms. While no such policy has been established, we are allowed to live among ghosts of the past: buildings, trees, and even animals from the previous century. Stanford as a place is a sedimented archive of multigenerational organisms co-existing. The physicality of Stanford belies a series of decisions and histories that are occluded from its present form. On a biological level, the origins of these trees is unknown and, further, such information is beyond the care of students who have a set of other everyday concerns: who decided to move the Cactus Garden, why is there a slice of a thousand year old redwood in the Hoover basement, why did David Starr Jordan plant a titoki tree on Campus Drive?
