From a seed no bigger than one from a tomato, California's coast redwood may grow to a height of 367 feet and have a width of 22 feet at its base. Imagine a 35-story skyscraper and you have an inkling of the trees' ability to arouse humility. Fires are the lifeblood of a conifer forest, and human development creates the need for prescribed burns for the health and longevity of the forest. This is California's Redwood National Park.
