Spruce Burl Forest
The Spruce Burl Grove lives on the edge of a 100 foot cliff on the southern end of the Olympic Coast. In the direct path of fierce Pacific winds that reach up to 100MPH and carry dense salty air, the trees have formed a unique response to their environment; they grow large bulbous growths ("burls"), reaching up to 5 feet in circumference. Although still under study, the burls serve three purposes in their survival. First, the burls strengthen the trees trunks adding weight and girth critical to their early survival in the windy environment. Second, the burls act as an aerodynamic foil---routing hurricane force winds around their bodies. Finally, the giant growths help deflect falling trees knocked down by the strong Pacific winds. Although burls appear throughout the tree world, they tend to serve reproductive purposes. Here, in a small patch of land on the edge of oblivion, one adaptation for a radically different purpose, serves another.
