To prevent the spread, the transportation of these materials out of infested areas is regulated by state and federal quarantines. The impacts of invasive species include: Reduced biodiversity; Decreased availability and quality of key natural resources; Water shortages; Increased frequency of wildfires and flooding The Invasive Species Program has identified numerous actual and potential invasive species from which we strive to protect California’s wildlands and waterways. Rodents of unusual size. “But there are a lot of them in the Great Smoky Mountains, which is the last place you’d want them because there are so many sensitive species there.”. In North Carolina, where hemlock wooly adelgid was detected in 1995, the tiny insect has caused the widespread decline of hemlock trees along the Blue Ridge Parkway and in the Great Smoky Mountains National Park, according to Bardon. In the 1970s, the U.S. imported them to help keep aquatic farms clean, control weeds in canal systems and help with sewage treatment. Extinctions have proliferated. National Invasive Species Awareness Week (February 24-28) is designed to raise awareness of invasive species and what people can do to prevent their spread. Kudzu is an invasive plant species in the United States.Its introduction has produced devastating environmental consequences. Results: Across the 42 studies, IAPs had a decreasing or neutral effect on native animal abundance and richness and significantly changed species composition. Burmese pythons (Python bivittatus) are considered invasive species in southern Florida, because they are an exotic species that have had many negative effects on this new environment. Here are seven invasive species that still pose a threat to the U.S. today. Invasive species can cause extinction to plants and animals in the Everglades by severely interrupting activity in their environment. 4 This has given them a solid stronghold in the area. HISTORY reviews and updates its content regularly to ensure it is complete and accurate. The subtropical climate and abundant water (which helped make the original biodiversity so rich), combined with increased human-induced nutrient pollution, makes The Everglades attractive to many animals and plants, which can live very well there and since they have no natural enemies they can breed until they take over habitat used by native species.

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 controls by $6 million annually". They’re also an expensive pest to deal with: Between 1980 and 1994 alone, the U.S. spent an average of $30 million annually on gypsy moth eradication, suppression and research. The cost of controlling these vines is increasing by $6 million annually as their growth easily outpaces moving and herbicide spraying. Kays, whose most recent paper documents the expansion of coyotes across North and Central America, said the canines actually play an important ecological role by partially filling the niche left vacant by wolves and other large predators that once roamed the southeast and specialized in hunting the region’s deer and small mammals. In recognition, we sat down with researchers at the College of Natural Resources to discuss invasive species and their impact on North Carolina.

Lionfish have become the poster child for invasive species issues in the western north Atlantic region. An invasive species is any living organism — plant, animal, insect or microbe — that is introduced to an area outside of its original range and causes harm to the environment, the economy or even human health, according to Dr. Robert Bardon, Associate Dean of Extension and Engagement at the College of Natural Resources and Professor in the Department of Forestry and Environmental Resources. 1 The primary means of transport between lakes is on boats, boat trailers, water skis, scuba gear and waterfowl. From mid June and well into August, females deposit their eggs between layers of outer bark and in cracks and crevices of the trunk and major branches.
