Invasive species are a crucial threat to many native habitats and species of the United States and a significant cost to agriculture, forestry, and recreation. An invasive species refers to an organism that is not native to a specific region and poses significant economic and environmental threats to its new habitat. [1] The term "invasive ...
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 ...
However, some plants grow a little too well. “Invasive plants spread aggressively and cause environmental changes, such as the elimination of native plant populations,” says Justine Kandra ...

The Massachusetts Invasive Plants Advisory Group lists over 30 invasive plant species for our state. According to the group, "'Invasive' plants are non-native species that have spread into native ...
Non-native invasive species can disrupt ecosystems because they do not have natural predators, or other ecological checks-and-balances. Thus, with less competition from native species, non-native populations can explode. [9] Invasive insects and pathogens have eliminated entire tree species from forests of the United States in as little as decades.
An invasive species is a non-native plant or animal, usually brought in by people, that is well suited or adapts to the new habitat, outcompeting native species and threatening the local ecosystem.
For example, invasive plants can alter the fire regime (cheatgrass, Bromus tectorum), nutrient cycling (smooth cordgrass Spartina alterniflora), and hydrology in native ecosystems. [89] Invasive species that are closely related to rare native species have the potential to hybridize with the native species.
