Invasive species are a large financial cost to the forest industry. Invasive species, specifically invasive plants, can interfere with forest regeneration and productivity through direct competition with tree seedlings, resulting in reduced density and slowed growth rate of tree saplings. Allen Abstract: Alien invasive species pose a serious threat to the ecological and economic sustain ability of Canada's forests. They do not cause damage to trees and plants, but they do change the natural biological diversity of local ecosystems by crowding out indigenous species. There are hundreds of species of non-native insects in our forests; several species, due to lack of host resistance and lack of natural enemies, have caused significant damage to our natural and urban forests. Like any traveler coming from abroad, they arrive by air, water or land. These species are termed invasive if they are able to modify indigenous ecosystems either as pests or competitors.

This definition, as would be expected given its source, focuses on the impacts of invasive alien species on biodiversity. Forest canopy openings of any kind lead to invasions by non-native invasive plant species, creating a dilemma for forest managers. The introduction of these pests is usually accidental, but other pests may have been introduced intentionally, although their dispersal into nature can be accidental.
