Selected Invasive Plants of Alaska

"When trying to identify an unknown plant, color photos often help.[] Non-native invasive plants displace native vegetation, degrade wildlife habitat, and negatively affect human health, the economy, and the environment. Factors such as geographic isolation and harsh winters have protected Alaska from large-scale invasive plant infestations in the past. Recently, however, some of the most harmful noxious weeds of the lower 48 states have begun to grow and spread in Alaska.

Many of the invasive plants featured [here] have been responsible for significant economic losses and environmental damage across North America over the past twp centuries. Other species featured here (Siberian peashrub and European bird cherry) have been dependable components of Alaska's urban landscape, but were included because they have recently been observed spreading aggressively into Alaskan wildlands and natural areas." less ↑
