Useless (?) trivia:
Eucalyptus oil was used for air purification purposes in early mining operations. Burning it apparently pulls carbon dioxide out of the air.
But do some reasearch before you try this at home. My source on this is a bit unreliable.

Yhe primary weed is (Eurasion?) Water Milfoil. Purple Loosestrife is also a problem. Yeah Zebra mussels are also a bitch with their always traveling in herds and their endless chattering about PH...........................

I got this through word of mouth, so take it with a grain of salt...

Back during the gold rush, some brainiac came up with the brilliant idea of importing eucalyptus trees to the SF bay area. They grew quick, and could be used for lumber for all those houses people wanted to build in such a hurry.

But he brought over the wrong kind. He brought over a kind of eucalyptus that was unsuited for construction, furniture, or much of anything. Except for taking over the local landscape.

Conservation groups have been going after the local eucalyptus in the last few years. A friend of mine was a volunteer to help clear out a patch of them from Angel Island (in the bay) a few years back.

sounds like botany to me

No, out of place flora and fauna can be very unwelcome. Like the zebra mussels and some kind of water weed who's name I forget are here in Minnesota -- they have no naural predetors and spred uncontrolablly. They attack or compete with local wildlife and boaters are warned to check for them to prevent moving them to new sites.
