Arizona Noxious Weeds and Invasive Species Noxious Weeds: A Disaster Looking for a Place to Happen in Arizona!! by Larry D. Howery and George B. Ruyle There is a very serious problem creeping into our state that has the potential to adversely affect each and every Arizonan. This problem is particularly sinister because by the time it becomes widely noticeable, it will probably be too late to do much about it. Whether you are a camper, hunter, fisherman, farmer, rancher, recreationist, birder, wilderness advocate, environmentalist, or even if you have no interest in outdoor activities of any kind, noxious weeds threaten the quality of natural resources on both public and private lands, and will potentially cost Arizonans millions of tax dollars-unless we do something, now What Is A Weed? What Is A Noxious Weed?
Extractions: Purpose: To provide information on Noxious, Invasive, Alien and other problem plant species that threaten the success of wetland restoration and enhancement projects. This report defines the different categories of problem species, identifies the threats to success caused by these species, recommends methods of avoidance through planning and monitoring, and lists numerous species that negatively impact the function and value of wetland restoration and enhancement projects.

Extractions: One of my educational responsibilities is teaching people about threats posed by invasive/noxious weeds. In general, these are plants that pose threats to people, other organisms, and/or the environment. In past Backyard Gardener columns, I have written about several invasive/noxious species including yellow starthistle, hoary cress (whitetop), puncture vine, diffuse knapweed, giant salvinia, and sweet resinbush. Gardeners and nurseries have a role to play in invasive species prevention and management. As a reminder, invasive and/or noxious weeds are non-native plants whose introduction causes, or is likely to cause, economic or environmental harm or harm to human health. Human actions are the primary means of invasive species introduction. The word noxious is a term that means the plant has been designated as particularly undesirable by law or regulation. Noxious weeds are found on lists compiled by state, federal, or land management agencies. Invasive weeds may have no legal designation, but are often in the process of being listed as noxious. You may wonder why a plant can become invasive or noxious. Often it is because they have been removed from their native environment and introduced to areas where their natural enemies are not present. These natural enemies are often insects that feed on them, but can also be plant diseases, herbivorous animals, or other organisms that keep plant populations in check.

Extractions: A threat to BCs resources Foreign plant species escaping from the garden or landscape can have a devastating impact on native plants and animals. 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: VT Department Of Agriculture Creates Noxious Plants Rule To Combat Invasive Plant Problem Click here to view the entire rule (pdf format) MONTPELIER- As warmer weather brings us back into our re-enlivened gardens, fields, and forests, The Nature Conservancy and the Vermont Department of Agriculture are asking Vermonters to check for plants that can escape cultivation and cause tremendous damage to the natural environment and the working landscape. Plants such as purple loosestrife, Japanese knotweed, common buckthorn, Japanese barberry, and some varieties of honeysuckle have been used widely in horticulture, landscaping and erosion control, and can be found in backyards, wetlands and forest edges throughout the state. At first glance these plants may look pretty, but their beauty is deceptive. Known as invasive species, plants like these are typically transplants from distant places. Once free from the natural checks and balances that kept them under control in their native realms, these plants can establish themselves in new areas and proliferate to the detriment of native species. They often hoard light, water and nutrients, and can even alter entire ecosystems by changing soil chemistry or hydrological processes. As a result, invasive plants can overtake native plants and, in turn, displace the animals that had relied on the native plants for food and shelter. With intentional and unintentional assistance from people, these problematic plants are spreading at an alarming rate, infecting natural areas across the United States.

Invasive Species Easier invasive species occur outside their natural range. 6) noxious,invasive, and Alien Plant species at the Wetland Science Institute HTTP//WWW. http://42explore.com/invasive.htm
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.

How Are Weeds Evaluated During The Weed Listing Process A reason to believe the species is invasive or poses a potential threat The species was once present in Washington and on the state noxious weed list. http://www.nwcb.wa.gov/weed_list/weedlisting.html
Extractions: How are Weeds Evaluated During the Weed Listing Process in Washington State? All plant species proposed for listing on the Washington State Noxious Weed List are evaluated by the Noxious Weed Committee (Committee). The Committee members include scientific advisors, State Noxious Weed Control Board (Board) representatives, selected county weed coordinators, and a representative from the Washington Native Plant Society. Committee meetings are open to the public. The Committee provides a recommendation to the Board about whether to list the plant and in which class (A, B, B-designate, or C). In some instances the plant is placed on a monitor list while being further evaluated by either a Committee member, the person proposing it for listing, or another individual selected as the sponsor. Although the monitor list has no legal standing, it allows the Committee time to research the species through literature review, talking to exotic plant managers in other states or countries, and to survey and evaluate existing Washington populations. Reasons for plant inclusion on the monitor list include: A reason to believe the species is invasive or poses a potential threat to Washington.
