"Today, a species’s immigration status often makes it a target for eradication, no matter its effect on the environment. Eucalyptus trees, charged with everything from suffocating birds with their resin to elevating fire risk with their peeling bark, are the targets of large-scale felling.
Yet eucalyptuses are not only majestic trees popular with picnickers, they are one of the few sources of nectar available to northern Californian bees in winter and a vital destination for migrating monarch butterflies.
Or take ice plant, a much-vilified Old World succulent that spreads its thick, candy-colored carpet along the California coast. Concerned that it is crowding out native wildflowers, legions of environmental volunteers rip it from the sandy soil and pile it in slowly moldering heaps along the cliffs.
Yet ice plant, introduced to the West Coast at the beginning of the 20th century to stabilize railroad tracks, is an attractive plant that can also deter erosion of the sandstone bluffs on which it grows."
