Invasive insects and pathogens are a serious threat to many forests in the United States and have decimated populations of several tree species, including American chestnut, American elm, eastern hemlock, whitebark pine, and the native ash species (see extended listing below). The loss of these tree species is typically rapid with both short ...
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
This is a list of invasive species in North America.A species is regarded as invasive if it has been introduced by human action to a location, area, or region where it did not previously occur naturally (i.e., is not a native species), becomes capable of establishing a breeding population in the new location without further intervention by humans, and becomes a pest in the new location ...
Unlike most invasive species, coyotes are native to North America, with a natural habitat that extends from Alaska to Central America over terrain ranging from mountains to plains to -- these days ...
Here are some of the most prominent invasive species in New York. ... While New York’s forests have been described as the lungs of the state, they also play a vital role in the state reaching ...
Kudzu is an invasive plant species in the United States, introduced from Asia with devastating environmental consequences, [1] earning it the nickname "the vine that ate the South". It has been spreading rapidly in the Southern United States , "easily outpacing the use of herbicide, spraying, and mowing, as well increasing the costs of these ...
The insatiable invertebrates, native to east-central Asia, are believed to have been introduced to the United States in the late 1800s, likely as hitchhikers in potted plants.
Invasive earthworms have caused a decrease in diversity, seedling populations, forest floor organic matter volume, and overall habitat quality. In addition, there is often an increase in invasive species and a decreased diversity of non-plant organisms. Some species that provide important biological niches to the ecosystem may be eradicated.
