Title: Arno and the Trees Location: Near San Francisco Country: USA Subject notes: The redwoods of western California, Sequoia sempervirens, are the tallest trees in the world, can live for more than 2000 years, and are one of the few species that is able to live long enough to wait for a suitable habitat to return around them for proper mass seeding. In the meantime, when a tree falls down, it becomes a nursery for many young trees that grow from shoots around the old tree's trunk forming a ring around the old base. In this way, though several centuries can pass by without much reproduction by seed, it is only a portion of their lifespan, and thus of little importance to the survival of the species.
