Redwoods have a number of endearing habits, which to them are processes of
survival but to us can appear somewhat magical. Take, for instance, these
two trees to the left, which grew so close together that they have begun to
overlap at the bottom. Some find the sight romantic; there are a pair of
such trees in Sequoia National Park they call "the lovers."
In other cases redwoods will form tree circles. When one tree is injured, it
will send out a shoot so a new tree will grow. Eventually the older tree
will surround itself with these younger "children," and when the original
tree finally dies, its remains nourish the other trees which have grown in a
circle around it.
