Alien Invasive Species

Alien, or non-native, species are plants, animals and microorganisms that have been introduced by human action outside of their natural distribution. Alien invasive species are those alien species whose introduction or spread causes environmental and economic harm.

Alien invasive species are considered the greatest threat to biodiversity following habitat loss. Alien invasive species become predators, competitors, parasites, hybridizers and diseases of our native plants and animals and are therefore left to flourish as they take over their new surroundings, eliminating native species populations and ultimately resulting in a loss of biodiversity and a changed ecosystem. The impact of invasive alien species is severe and often irreversible.

CWF has developed several initiatives to educate the public about the impacts of invasive alien species on the ecosystem, the economy and human health. Undoubtedly, alien invasive species education will be an integral component of climate change and water policies and programs. CWF also joined Great Lakes United and Nature-Action Québec to launch the “Les Horticulteurs en action” educational program aimed to increase awareness of invasive plant species. This program is targeted to the horticulturist sector and educates college students and professionals about the impact of horticulture on habitat conservation. It also encourages the commercial production of indigenous plant species. CWF has also provided funding to the Ontario Federation of Anglers and Hunters in support of its awareness program in Ontario.
