Eucalyptus Bowl

Eucalyptus globulus, the Tasmanian bluegum, southern blue-gum or blue gum, is an evergreen tree, one of the most widely cultivated trees native to Australia. They typically grow from 30–55 m (98–180 ft) tall.

It was introduced to California in the mid-19th century, partly in response to the Southern Pacific Railroad’s need for timber to make railroad ties, and is prominent in many parks in San Francisco and throughout the state. Naturalists, ecologists, and the United States National Park Service consider it an invasive species due to its ability to quickly spread via seeds and displace native plant communities, while local authorities, especially many fire departments across California consider it to be a major fire hazard. Due to these factors, programs across the state of California have been established to remove all eucalyptus growth, and restore native biomes in certain park areas.
