-Asian carps were brought from Asia to North America in the 1960s and 70s. Since then they have migrated north through U.S. waterways towards the Great lakes. Preventing Asian carps from spreading into the Great Lakes is the best way to prevent harm to Ontario’s native fish species

-Asian carps prefer cool to moderate water temperatures, like those found near the shores of the Great Lakes. If Asian carps become established in Ontario waters, they could potentially eat the food supply that our native fish depend on and crowd them out of their habitat. The decline of native fish species could damage sport and commercial fishing in Ontario, which brings millions of dollars a year into the province’s economy.

-found in all the Great Lakes and in more than 100 inland lakes in Ontario. The species has also been reported in Lake Winnipeg and the Winnipeg River in Manitoba.

-nothing is being done to stop it.

In Canada, the first western spruce budworm epidemic was reported in 1919 on Vancouver Island

The

mountain pine beetle (MPB) is a native insect that attacks pines in western North American forests.

The current MPB outbreak started in British Columbia in the early 1990s. The insect has since killed about 50% of the total volume of commercial lodgepole pine in the province. While isolated records of MPB had been noted in Alberta before, it was the massive migration of beetles into that province from outbreaks in British Columbia during 2006 that fuelled the spread eastward.

they mine expanding buds. Later, they spin loose webs around new foliage and feed within the webbing, often chewing needles off at their bases. They will feed on old foliage once new growth has been destroyed. They are voracious feeders, causing severe defoliation.

Nevertheless, the spruce budworm is one of the most damaging native insects affecting spruces and true fir in Canada. During a major outbreak, tens of millions of hectares of trees can be severely defoliated by the insect.

1.  Dendroctonus ponderosae, is a species of bark beetle.
2.  Western North American forests from Mexico to Central  British Columbia.
3. Forest ; research being conducted by the Canadian Forest Service and other agencies focuses on gaining greater understanding of the ecology and population dynamics of MPB in the insect’s new environment.
4. Their efforts include detecting MPB in new areas and removing and burning infested trees to reduce further attack, or harvesting affected stands before the economic value of the wood is lost or diminished.
