I have a neighbor who owns a piece of property where the house had burned down 40 years ago. Like many folks at that time, the house had eucalyptus trees around it. When it burned down the eucalyptus seed spread for a quarter mile. Now those trees adjoin my property, even hanging over it in places. Why should I have to pay the time and money to deal the consequences if those trees burn and the seeds sprout all over my land?
I have no love for the police state tactics of the County of Santa Cruz, but if someone had been paying more attention to imported plant material we wouldn't have blackened, dying madrones or sudden oak death. America would still have chestnuts and elms.
