Extractions: The Topic: Invasive Species Easier - Invasive species occur outside their natural range. They are nonnative plants and animals that harm or endanger native plants and animals or other aspects of biodiversity. Alien invasive species occur in all groups of plants and animals. They include competitors, predators, pathogens and parasites. They have invaded almost every type of native ecosystem and caused hundreds of extinctions. Harder - Whether called invasive, nonnative, alien, exotic, or non indigenous; introduced species are those life forms that have evolved elsewhere and been purposely or accidentally moved to a new location. Some have invaded habitats by themselves (e.g., migrating wildlife, plants, and animals rafting on floating debris); however, human exploration, colonization, and commercial trade have dramatically increased the diversity, scale, and impact of the invasions. Introduced species often find no natural enemies in their new habitat and therefore spread quickly and easily. Invasive species are a real threat to our environment and economy. Economic costs of nonnative species invasions in the United States reach billions of dollars each year. These biological invasions produce severe, often irreversible impacts on agriculture, recreation, and natural resources. Invasive species threaten biodiversity, habitat quality, and ecosystem function. They are the second greatest threat to native species, behind habitat destruction. They have contributed to the decline of over forty percent of U.S. endangered and threatened species. Introduced species also present an ever-increasing threat to food and fiber production.

Extractions: Wood packaging EIS From: phytodoer@aol.com (Faith T. Campbell, Invasive Species Program) INVASIVE SPECIES America's forests and other ecosystems are threatened by invasions of exotic species of insects, disease pathogens, and plants. Already, insects, fungi, and disease pathogens introduced from Europe and Asia have damaged 70% of the 165 million acres of forest in the Northeast and Midwest. Exotic weeds infest a total area as large as Texas; they are damaging half our National parks and 60% of preserves managed by The Nature Conservancy. Invasive exotic species threaten nearly half of all America's imperiled species. Inadequate Responses to Bio i nvasion Every day, new species are brought into the country species that may prove to be as harmful as those already wreaking such havoc. Many come in as unwanted "hitchhikers" on various types of cargo, including on imported logs, lumber and wood chips; in wooden packing crates and pallets; on imported plants, fruits, and cut flowers; in ships' ballast water; even attached to the ships and planes themselves.

Extractions: "Science in Wildland Weed Management" Symposium, Denver, CO, April 8, 1998 "The invasion of noxious alien species wreaks a level of havoc on Americas environment and economy that is matched only by by damage caused by floods, earthquakes, mudslides, hurricanes, and wildfire. These aliens are quiet opportunists, spreading in a slow motion explosion. Each year noxious weeds exact an ever-heavier toll: Farmers and ranchers spend more than $5 billion just for control. Losses to crop and rangeland productivity exceed $7 billion. Weeds infest 100 million acres in the U.S., spread at 14 percent per year, and on public lands consume 4,600 acres of wildlife habitat per day. They diminish or cause the extinction of native plants and animals, a third of all listed species. They homogenize the diversity of creation. They ignore borders and property lines. No place is immune. Consider the damage done by purple loosetrife, a beautiful, seemingly harmless flower one might be pleased to find in a meadow. But not for long. For this species, found in 36 states, costs $45 million to manage. To bring this into a statewide perspective, consider that Florida spends $11 million each year to manage water hyacinth. Tropical soda apple, first reported in Florida, now covers 370,000 acres and costs the state $28 million. In the past it was, again, much easier for an individual, a state, a federal agency to dismiss this invasion as someone else's problem. And so the weeds slowly, silently, almost invisibly, but steadily spread all around us until, literally encircled, we can no longer turn our backs on it. The invasion is now our problem. Our battle. Our enemy.

Extractions: NOXIOUS SEAWEED FOUND IN SOUTHERN CALIFORNIA COASTAL WATERS Rachel Woodfield Dubbed "killer algae," the alien seaweed Caulerpa taxifolia was discovered in June 2000 in a coastal lagoon in Carlsbad, California, within San Diego County. An aggressive clone of this species has already proven to be highly invasive in the Mediterranean Sea, where the governments of France, Spain, Monaco, and Italy have been unable to control its spread. The first confirmed American occurrence of this invasive species in California has caused considerable alarm. The resulting press coverage of the issue led to discovery of a second infestation of Caulerpa taxifolia in Huntington Harbour in Orange County (about 75 miles north of the Carlsbad occurrence). Genetic studies have determined these two infestations to be of the same clone threatening the Mediterranean Sea. Efforts are underway to eradicate Caulerpa taxifolia from California and control its spread before the infestation reaches the magnitude seen in the Mediterranean. Caulerpa taxifolia is a green alga native to tropical waters that typically grows to small size and in limited patches. In the late 1970s this species attracted attention as a fast-growing and decorative aquarium species that became popular in the saltwater aquarium trade. A clone of the species was cultured for display at the Stuttgart Aquarium in Germany and provided to aquariums in France and Monaco. Around 1984 this species apparently escaped or was released from an aquarium into Mediterranean waters, and rapidly spread from an initial patch of about one square yard to over two acres by 1989. Meinesz reports that by 1997 it blanketed more than 11,000 acres of the northern Mediterranean coastline and has recently been reported off northern Africa. Genetic analysis suggests that all

Please help in protecting the natural environment of British Columbia! BCs noxious weeds are typically exotic or non-native plants that have been introduced to this province without their natural predators. Left unchecked, these weeds destroy our native plant and animal habitat. They are among the top cause for losses in the natural diversity of our environment, and are devastating to the economy. Weeds cause crop losses well in excess of $50 million annually in BC. Invasive plants have the capacity to move into a habitat and reproduce so aggressively that they displace the original vegetation. They: crowd out native plants, including rare and endangered species destroy wildlife habitat reduce crop yields (on average 10 to 15 %) reduce crop quality (taint food products with off flavours, toxic berries, spines, etc.)

Extractions: Skip Navigation Links BLM National List of Invasive Weed Species of Concern The definition of "weed " is always debatable. Traditional definitions include "plants out of place" or "plants that by their presence conflict with management objectives for the site." The defintition included here also tries to incorporate the concepts of public land health and sustainability. A weed is defined as "a non native plant that disrupts or has the potential to disrupt or alter the natural ecosystem function, composition and diversity of the site it occupies. It 's presence deteriorates the health of the site , it makes effecient use of natural resources difficult and it may interfere with management objectives for that site. It is an invasive species that requires a concerted effort (manpower and resources) to remove from its current location, if it can be removed at all. " This definition is adapted from Noss and Cooperider (1994) and Beck (personal communication).
Extractions: Invasive species are noxious weeds, insects, and plant diseases - non-native to Nevada - that raise havoc with the environment, economy, and public health. There are many types of invasive species throughout the Ely District. Noxious weeds are the most commonly seen invasive species. Currently there are several programs in place to help combat the spread of noxious weeds. Below is a list of some of the noxious weeds in our district.
Invasion Of Undesirable Plant Species (Weeds) officially recognised as Federal noxious Weeds and many more species are designatedon State noxious Weed lists. Experts estimate that invasive plants already http://lead.virtualcentre.org/en/dec/toolbox/Grazing/InvWeed.htm
Extractions: After initial introduction, invasive plants are capable of spreading to cover large areas. This invasion poses a serious threat to the integrity and productivity of rangelands. An example from the United States serves to illustrate the nature and extent of the problem (Box 1), but the problem itself occurs world-wide. Box 1 Of the thousands introduced plant species currently established in the United States, 1400 are scientifically recognised as pests. Ninety of these species are officially recognised as Federal Noxious Weeds and many more species are designated on State Noxious Weed lists. Experts estimate that invasive plants already infest well over 100 million acres and continue to increase by 8 to 20 percent annually. This means 3 million acres, an area twice the size of the state of Delaware, may be lost to invasive plants each year. In particular, invasive plants are recognised as a direct threat to agricultural production and biodiversity in the United States. Invasive plants adversely impact croplands, rangelands, forests, parks, preserves, wilderness areas, wildlife refuges and urban spaces. The habitat of two-thirds of all threatened and endangered species is threatened by invasive species.
Extractions: Invasive non-native plants species are an increasing threat to native populations of plants and animals. Exotic plant species introduced into favorable habitats can reproduce in large numbers; their populations often literally explode. This is primarily due to the fact that many non-native species are more aggressive and adaptable because they have no natural predators and readily replace the native plants. Restoration of native grasses and forbs on cropland is a major activity to control invasive plants. The seeding of native plant communities on cropland supports the recovery of grassland dependent birds; expands the potential for recruitment of ground nesting ducks; and reduces the need for chemical herbicide application. Wyoming In the North Platte River area of Wyoming, the Partners Program worked with one landowner to develop a rotational grazing system on 5,000 acres of upland and riparian habitat to control invasive cheatgrass . Historic use of the ranch encouraged a conversion of native shortgrass prairie to non-native cheatgrass. The monotypic stand of cheatgrass directly effects the number and diversity of wildlife species inhabiting the ranch. The grazing system was developed to pressure the cheatgrass at critical times allowing the native grasses and forbs to respond and outcompete the cheatgrass.
