(Eucalyptus grandis and related species)
Eucalyptus species were introduced to the United States for timber, windbreaks, and ornamental use. In parts of Florida and California, some species have escaped cultivation and become invasive, particularly in wetlands and disturbed habitats. These fast-growing trees can alter soil conditions, reduce available water, and increase wildfire risk due to their flammable oils and leaf litter. Invasive behavior varies by species and region.
