Give an example seen on the field trip. What kinds of effects can an invasive species have?

An example seen on the field trip was the eucalyptus trees. Some effects invasive species have are changing the functions of the ecosystem, unintentional use of forest pest species and plant pathogens can change forest ecology and can have negative impacts on the wood industry, and genetic pollution, where wild species can be threatened with extinction. 12.
