" Trees evolved to grow together in a forest. They intertwine their roots, forming a root matrix that is nearly impossible to uproot. Forest trees with interlocked roots may snap off in big winds, but they typically don’t uproot. Because aesthetics have trumped function for so long, we have planted large, isolated specimen trees ready to blow over nearly everywhere. If we change our goal from creating majestic specimen trees to picturesque groves of trees, the interlocking effect of root matrices will be strongest. "
