Eucalyptus Grove, Grinnell Natural AreaUC Berkeley
The Metcalf Eucalyptus Grove · Grove was planted in 1877 with Tasmanian blue gum (Eucalyptus globulus) · Stands at the junction of the north and south fork of Strawberry Creeks. · Eucalyptus trees are the tallest hardwood trees in the world. This grove is the tallest in California · Eucalyptus planting craze swept through California in the 1870s:
-timber crisis due to the clearing of oaks in coastal regions
-French research discovered eucalyptus’ ability to “purify the air and eliminate malaria”
-Blue gum eucalyptus was known to be fire-proof, have medicinal value, and produce timber.
-It became a patriotic duty for Californians to plant eucalyptus.
-Beside the use of eucalyptus in cough-drops, these attributes proved to be fiction.
· They are now a fixed part of California’s landscape ranging from San Diego County to Douglas County in Southern Oregon. · Eucalyptus is now used for wind-breaks, firewood, aesthetics, and pulp production.
