Managing Exotic Invasive Species in Ontario’s Hardwood Forests: How landowners and woodlot managers can protect their forest ecosystems
Exotic invasive species (EIS) are plants, insects or pathogens that, either intentionally or not, have been introduced to a new habitat where they have the ability to cause harm to the environment, the economy and/or society. A variety of EIS are detrimental to the hardwood forests of Ontario. For example, invasive plants can alter forest integrity through rapid population expansion. They can out-compete many native species and cause shifts in species abundances, thereby altering the forest ecosystem.
