Despite these issues, there are calls to preserve the "Eucalyptus" plants in California. Advocates for the tree claim its fire risk has been overstated. Some even claim that the "Eucalyptus's" absorption of moisture makes it a barrier against fire. These experts believe that the herbicides used to remove the "Eucalyptus" would negatively impact the ecosystem, and the loss of the "Eucalypti" would release carbon into the atmosphere unnecessarily. There is also an aesthetic argument for keeping the "Eucalyptus"; the trees are viewed by many as an attractive and iconic part of the California landscape. Many say that although the tree is not native, it has been in California long enough to become an essential part of the ecosystem and therefore should not be attacked as invasive. These arguments have caused experts and citizens in California and the Bay Area to debate the merits of "Eucalyptus" removal versus preservation. However, the general consensus remains that some areas urgently require "Eucalyptus" management to stave off potential fire hazards.
