	Invasives
		An invasive species that colonizes a new area may gain an ecological edge since the insects, diseases, and foraging animals that naturally keep its growth in check in its native range are not present in its new habitat.
		Invasive plant species thrive where the continuity of a natural ecosystem is breached and are abundant on disturbed sites like construction areas and road cuts.
		Plants selected for their aesthetic value may be hard to banish from your garden even after their invasive tendencies are revealed.

	Invasive Plants
		Invasive plants are plants which grow quickly and aggressively, spreading and displacing other plants.
		Invasives are usually introduced by people either accidentally or on purpose, into a region far from their native habitat.
		Identifying invasive plants and understanding the potential damage they can cause is essential to stopping their spread and protecting native vegetation.

		Invasive plant species are among the greatest threats to the integrity of natural areas.
		Invasive species – a non-native (adventitious) species that is capable of moving aggressively into a habitat and monopolizing resources such as light, nutrients, water, and space to the detriment of other species.
		Invasive species have contributed to the decline of 42% of U.S. endangered and threatened species, and for 18% of U.S. endangered or threatened species, invasives are the main cause of their decline.

		According to Executive Order 13112, signed on February 3, 1999 and establishing the National Invasive Species Council, an "invasive species" (including plants) is defined as an alien species whose introduction does or is likely to cause economic or environmental harm or harm to human health.
		Usually the invasive nature of the plant was unknown before it was introduced, but without the diseases or pests that would have kept the plants in check where they naturally occurred, the plants were able to proliferate and become invasive.

	Invasive Plants of the Eastern United States: Identification and Control
		Variously referred to as exotic, nonnative, alien, noxious, or non-indigenous weeds, invasive plants impact native plant and animal communities by displacing native vegetation and disrupting habitats as they become established and spread over time.
		In fact, many non-native plants introduced for horticultural and agricultural use now pose a serious ecological threat in the absence of their natural predators and control agents.
		This publication will aid landowners, foresters, resource managers, and the general public in becoming familiar with invasive plants in their area to help protect our environment from the economic and ecological impacts of these biological pollutants.

	ScienceDaily: Invasive Plants Prefer Disturbance In Exotic Regions Over Home Regions
		Science Daily — One of the most invasive exotics in the western United States, the yellow starthistle, is successful both at "invasion" in non-native areas and "colonization" in native ones.
		The researchers conducted their research over three years in southern Turkey, where the weed is native, and in California and central Argentina, two regions where the weed is non-native and remarkably abundant.
		Their findings, published in the August issue of The American Naturalist, question the assumption that disturbance alone is sufficient to explain the remarkable success of invasive plant species in non-native ranges.
