Ailanthus (Ailanthus altissima)

Ailanthus, also known as tree-of-heaven and paradise-tree, is a major nuisance to foresters, farmers, and homeowners alike. Its prolific seeding and ability to sprout from roots and stumps and grow quite rapidly just about anywhere make it a serious competitor and threat to native species and cultivated crops. On top of that, ailanthus is allelopathic, producing substances that are toxic to and inhibit the growth of neighboring plants.

Autumn Olive (Elaeagnus umbellata)

Autumn olive was introduced to the U.S. from Japan and China in 1830. It was originally planted for wildlife habitat, shelterbelts, and mine reclamation, but has escaped cultivation. It is dispersed most frequently by Autumn olive was introduced to the U.S. from Japan and China in 1830. It was originally planted for wildlife habitat, shelterbelts, and mine reclamation, but has escaped cultivation. It is dispersed most frequently by birds and other wildlife, which eat the berries.

Honeysuckle (Lonicera spp.)

Several species of Asian honeysuckle have been introduced in the United States for their ornamental and wildlife values. Honeysuckle is perhaps the most widespread exotic invasive in the U.S., now found in at least 38 states. The Asian honeysuckle produces abundant seeds which are dispersed by birds and other wildlife. It also spreads by sprouting from its roots. Because it tolerates shade from other plants, it grows in forest understories.

Invasive Plant Pest Species of South Carolina

Invasive, or exotic pest plant species are a growing problem in South Carolina. Nonnative plant invasions can be seen in natural areas, croplands, rangelands, pastures, forests, wetlands and waterways, wilderness areas, parks and refuges, and highway rights-of-way.

Invasive Plant Responses to Silvicultural Practices in the South

This guide is intended to aid foresters and managers in the southeastern United States in developing management plans and managing forests threatened by invasive plants. This guide integrates identification of invasive plants, potential mechanisms for spread (natural seed or vegetative production, or human induced spread by cultural practices) and a suite of silvicultural management/control practices.

Invasive Plants Field and Reference Guide: An Ecological Perspective of Plant Invaders of Forests and Woodlands

There are many field guides available about invasive plants and their identification. The purpose of this particular field guide is to give a scientific synthesis of what is known about the behavior of such species in managed, disturbed, and pristine forested systems in addition to key information for accurate identification. Such information will be helpful when prioritizing research questions and choosing the best control strategies.

Invasive Plants — A Horticultural Perspective

Invasive nonnative (nonindigenous) plants are the subject of a considerable amount of attention and debate. Stories about invasive plants are now common in the popular media. As purchasers of nonindigenous plants that have the potential to invade natural areas, consumers are links in the distribution chain of invasive plants. Other links are those who import, propagate, transport, and sell nonindigenous plants. Ultimately, the result is a potential impact on our natural environment.

Invasive Species

An invasive species is defined as a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health according to The Forest Service Framework for Invasive Species (USDA Forest Service, 2003). The framework notes that thousands of invasive exotic plants, insects, fish, mollusks, crustaceans, diseases, mammals, birds, reptiles, and amphibians have infested hundreds of millions of acres of lands and waters across the nation, causing massive disruption in ecosystem function, reducing biodiversity, and degrading ecosystem health. Forests, prairies, mountains, wetlands, rivers and oceans have each been infested by these aggressive exotic species.

Stop Cogongrass Hitchhikers

Cogongrass (Imperata cylindrica) continues its rapid spread across Alabama and the southeast, reducing forest productivity, destroying wildlife habitat, and affecting rights-of-way. this aggressive weed is spreading quickly by hitchhiking around the state, attached to skidders, road graders, mowers, food plot equipment, and other forest and road maintenance equipment.
