Eucalyptus trees, eucalyptus globulus, Berkeley, CA
A tree that is native to Australia, the eucalyptus also thrives in the San Francisco Bay Area. This has been a fiercely contested topic for over thirty years.
I am still a vagabond after the fires last month destroyed parts of our home, spent this past weekend at a friend’s in the Berkeley/East Bay area. This part of the Bay Area has many eucalyptus trees. One day I took a walk through a large cemetery. It was filled with eucalyptus trees, and I was reminded of the controversy.
Some people like the eucalyptus trees. The pungent fragrance, exotic multi-colored trunks, and tall stature are pleasing. The tree produces a sweet nectar that draws hummingbirds, and other birds. It has seed pods and seasonal flowers, and elegant pointy leaves. It has beneficial medicinal value, too.

I am always happy to see the flocks of yellow-rumped warblers that invariably visit groves of eucalyptus. The cheerful birds dance around in the tall treetops.
Other people despise the tree. The bark sheds in long strips, and sometimes limbs drop off too, making it a danger. Bark and pods and leaves litter the ground. Fire Departments all over California curse the flammability of the tree.
Moreover, a non-native invasive, they can overtake the native flora, and corresponding fauna as well. Due to its ability to readily re-sprout, it is nearly impossible to fully eradicate without use of strong pesticides.
Lawsuits, protests, campaigns, and debates have sparked the community for decades.

Atlantic magazine article about the debate.
As with much of Bay Area history, the California Gold Rush of the 1850s started the trend when the population dramatically increased. Lumber was needed to build housing. By the early 1900s entrepreneurs, like Frank C. Havens, a real estate developer, were certain this fast-growing tree was the perfect solution for quick lumber. He imported eucalyptus seedlings from Australia, and planted millions of trees all over the Bay Area.
Soon after, he discovered that the wood was too young for lumber use. The wood bent, cracked, and shrank.
In today’s bigger picture, there are 700+ species of eucalyptus, native to Australia and surroundings. There they call it “the gum tree.” Gum trees are everywhere. The leaves are the koala’s main diet.

One day while in Australia, we were looking for koalas in this grove (above). A ranger had told us we would find koalas here, and we had spent an hour searching for them, but found nothing. Then a farmer drove up (we were on his property), asked us if we needed help. We told him what we were doing, he leaned out of the front window, pointed up and showed us three koalas sleeping in the trees.

Eucalyptus globulus, also known as the Tasmanian Blue Gum, is the prevalent species in the Bay Area. They usually range in height from 98-180 feet tall (30-55 m).
The get-rich-quick themes of yesteryear have caused problems for native plants of today. All over the world there are theories and plans for eradicating invasive non-natives, making more hospitable space for native species; not just for eucalyptus trees, but for many plants and animals.
But as I stood underneath the Berkeley eucalyptus trees this past weekend, I filled my lungs with the refreshing aroma, and thanked them for their strength and beauty.
