A guide to the identification and control of exotic invasive species in Ontario's hardwood forests. Invasive alien species can become competitors or predators of indigenous species and their activities can eliminate habitats for some wildlife species through diminished biological diversity and even, in extreme cases, through the disappearance of particular species. An invasive species is an organism that is not indigenous, or native, to a particular area. For example, European gypsy moths were imported from France by an amateur entomologist who wanted to produce silk. They attack plantations and certain valuable species, such as pine, elm, oak and butternut trees. Alien: Species introduced into Canada’s forests within recent history. In 1869, a few of the moths escaped and rapidly propagated. For example, in newly invaded forests buckthorn and garlic mustard, both invasive species, increase notably in population density.

Social impacts are even more difficult to assess, but the following, which are or may be affected to varying degrees, can be pointed out: CFS scientists estimate that over 80 alien insects or diseases have been introduced into Canada since 1882, including several that have proven to be extremely destructive for Canada’s forests. Canada’s annual timber losses due to invasives are estimated at 61 million m3 which is equivalent to $720 million in losses (Canadian Action Plan for Invasive Alien Terrestrial Plant and Plant Pests (CFIA, September, 2004). Canadian should be aware of invasive species Early detection allows time for control efforts (e.g. Another invasive species, the Japanese seaweed Undaria pinnatifida, is also spreading on Tasmania’s east coast. It is suspected that the large-scale importing of pine logs from New England led to the introduction of pine shoot beetles into Quebec.

Controlling invasives, import restrictions, biosecurity. For example, in newly invaded forests buckthorn and garlic mustard, both invasive species, increase notably in population density. The Forest Service is a recognized leader in invasive species ecology, management, and research in the United States and internationally. The introduction of alien pests into a new environment, sometimes far away from their original environment, is most often accidental. But solely in terms of timber losses, we know that forest pests destroy about 400,000 ha of forest every year in Canada, which is slightly less than half of the 930,000 ha harvested annually by the forest industry. Canada’s extensive forests, especially those in proximity to urban areas are threatened by the same factors as elsewhere in the world. Fire management, timber harvest, grazing, mining, recreation, and agriculture have not only exacerbated invasive species establishment and spread, but have been impacted by such species as well. A recovery plan will be developed. It can form dense stands and is likely to threaten giant kelp forests in future. ISBN 978-1-55963-051-1. There are, however, other issues to consider when engaging in sustainable shipping and storage practices, namely, that of invasive species.

Leafy Spurge is native to southern Europe, and was recorded in Canada for the first time in the 19th century. Invasive species can also affect species behaviour and ecosystem function. To prevent damage by these alien pests, the Government of Canada has set up an Invasive Alien Species Strategy for Canada based on the prevention, early detection, rapid response and eradication, containment and control of invasive alien species in forests (IASFs) that nonetheless succeed in entering Canada. However, very few succeed in establishing a home here because of Canada’s generally effective natural barriers, such as climate, a vast land mass and topography. The economic impact of many invasive species is poorly documented because of the difficulty in assessing impacts to habitats, such as forests, rangelands, aquatic, wetland, and riparian sites. Thirty-six species, or … Another invasive species, the Japanese seaweed Undaria pinnatifida, is also spreading on Tasmania’s east coast. A recovery plan will be developed. In Quebec alone, 600,000 elm trees were destroyed or chopped down between 1945 and 1965 because of this disease. “Although invasive species are a worldwide problem, in the state of Rio de Janeiro the problem is worse, as more non-native than native primate species were recorded within the state.” Baskin, Yvonne (2003). Examples range from common weeds like dandelion and Canada thistle, backyard birds like House Sparrows and European Starlings, diseases like West Nile virus, crop- and forest-damaging pests like fruit moths and balsam woolly adelgid, to invertebrates that alter ecosystem function, such as golden star tunicate (sea squirt), zebra mussels and earthworms. Sadly, this is also true of London, where it is now two invasive species that hold the title for "most common tree" - European Buckthorn (by number of stems) and Norway Maple (by total size). The following is a list of the principal alien pests, along with their preferred hosts and estimated dates of arrival in Canada: More and more species reach our borders, particularly because of increased free trade; Modern-day forests are more vulnerable because they have been significantly modified by human activities; By definition, alien pests cause more damage than indigenous species because they have no natural enemies in Canada; Lastly, environmental considerations will limit the use of some control and eradication measures. We work with public and private organizations, tribes, states, and local landowners to address a wide range of aquatic and terrestrial invasive species. Outbreaks occur periodically. Examples range from common weeds like dandelion and Canada thistle, backyard birds like House Sparrows and European Starlings, diseases like West Nile virus, crop- and forest-damaging pests like fruit moths and balsam woolly adelgid, to invertebrates that alter ecosystem function, such as golden star tunicate (sea squirt), zebra mussels and earthworms. 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. ISBN 978-0-9291-0021-0. That said, the Great Lakes basin is one of the country’s most heavily affected ecosystems, with more than 180 known invasive species having arrived in the basin since the 19th century. In addition, invasive alien species can have far-reaching impacts on agricultural and forest production, water resources, ecosystem processes, economic activity, and human health. Canada’s extensive forests, especially those in proximity to urban areas are threatened by the same factors as elsewhere in the world. Like any traveler coming from abroad, they arrive by air, water or land. There is special concern over the potential Asian longhorn beetle outbreak. az1436.
