Redwood trees on UC Berkeley's campus

In this episode of Planet Berkeley, we visit the redwood trees on UC Berkeley's campus. By the late 1860s, almost all of the mature old growth Sequoia sempervirens, redwoods, in the Bay Area had been cut down to build San Francisco. The redwoods on our campus were all planted by Berkeley’s earliest landscape architects over 100 years ago, and now have well-developed root systems. These gentle giants are children yet — if we map their age to a human timeframe, they would be about six years old. Given the chance, they can grow up to 300 feet tall.
