Extractions: (as prepared) Thank you very much for inviting me to join you for this workshop on Invasive Species. As you may know, while the Legislature is in session, I am not allowed to come to the 3rd and 4th floors without an invitation. In other words, if the Legislature hadn't given me permission, then I would be the "invasive species" here. So I thank you for inviting me and I thank the Legislature for allowing me to come. And thanks to all of you for being here and contributing to this effort. I compliment the Idaho Council on Industry and the Environment and others for the development of this workshop. The ultimate success of our efforts to combat invasive species will depend on our ability to draw on the knowledge of local government, industry, non-profits, scientists, farmers, private citizens and the environmental community. Invasive species can be devastating to our precious natural resources, our agricultural and timberland, our national forests and parks, our waterways, rivers and lakes, and our wildlife. And at a time like this, when our farmers and ranchers are already dealing with tough economic conditions, invasive species can be the straw that breaks the camel's back.

A new species of the invasive aquatic weed spartina has been found at the west end of Grays Harbor, Washington state's only coastal, deep-water port. The new species, known as Spartina densiflora, was found recently by Les Holcomb, a state Department of Fish and Wildlife scientific technician, while he was performing a noxious weed survey. Scientists at the University of California at Davis in December confirmed the species through genetic identification. The infestation covers more than one-tenth of an acre near Point Brown at the southern tip of the Ocean Shores peninsula. Spartina is an invasive cordgrass that is taking over tideflats in Puget Sound and coastal Washington, altering natural fish and shellfish habitats and excluding native vegetation.
Brevard County Non Native Invasive Plants Certain species of nonnative, invasive vegetation have a variety of noxious qualities,including but not limited to, adverse effects on human health, hazards http://www.brevardcounty.us/environmental_management/plants_nnips_home.cfm
Extractions: Florida is among the four states with the highest plant diversity, containing over 4,100 different species. Of these, about 2,800 are native plant species and 1,300 are naturalized, non-native species. Only California, Texas, and Hawaii have similar levels of plant diversity. Floridaâs diverse and beautiful vegetation provides the quality of life that residents and visitors seek and enjoy. Florida, however, is being invaded and altered by non-native, invasive species of plants and animals. The tropical climate and numerous ports of entry expose Florida to more non-native, invasive species than most other states. Many species of plants and animals from other continents have arrived here, whether imported or introduced accidentally, since European settlement of the state. Native plant species are defined as having occurred naturally in Florida prior to European settlement in the 1500s. Non-native plant species include ornamentals and invasive species. Not all non-native plants are invasive. Many ornamentals are non-native, and currently do not demonstrate invasive properties. Some non-native plants, however, become naturalized, which means they have been found growing in native plant communities. Naturalized species comprise escaped cultivated species and invasive ones. A species is called invasive when it is naturalized and displacing native vegetation. Invasive exotic is another term meaning non-native, invasive species.

Invasive Weeds Diseases ALERT: Plum pox virus appeared, for the first time in North America, this past fall in fruit orchards in Adams County, Pennsylvania, adjacent to Carroll and Frederick Counties in Maryland. Visit the West Virginia University, Kearneysville Tree Fruit Research and Education Center web site , (www.caf.wvu.edu/kearneysville/disease_descriptions/ppvresources.html) for color images of the disease symptoms on fruits, leaves and seeds, and for more information about Plum pox virus. There have been no positively identified cases of plum pox virus in Maryland. This is a significant disease that affects all stone fruits except sweet and sour cherries. Aphids spread the pathogen from tree to tree and symptoms do not appear for up to four years after initial infection. All plant parts are affected and infected trees decline and die. It is very important that the disease be contained and hopefully eradicated. If you notice unusual symptoms on peach, plum, apricot or nectarine trees please call your county Extension office or call HGIC at 1-800-342-2507.
Extractions: Forest Health Technology Enterprise Team. FHTET-2003-08 A biological invasion of non-native plants is spreading into our nations' fields, pastures, forests, wetlands and waterways, natural areas, and right-of-ways. 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. Drawing on recent publications by the USDA Forest Service, National Park Service, U.S. Fish and Wildlife Service, USDA APHIS PPQ and the Southeast Exotic Pest Plant Council, this web site covers identification characteristics, distribution, and control options for 97 tree, shrub, vine, grass, fern, forb, and aquatic plant species that are invading the eastern United States. For each species, a menu of control options is presented, including mechanical treatments, specific herbicide prescriptions, and, for selected species, recent advances in biological control. While this is not an official list of "invasive" plants throughout the eastern United States, it includes Federal Noxious Weeds and those listed by State regulatory agencies, pest plant councils and other organizations. Some of the plants on this list are often found in ornamental plantings and landscapes. 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.

Extractions: Texas Law Control of Prohibited Plants Prohibited Plant Species Links to Other Sites The spread of exotic plants in some state waters have chocked water ways and rendered portions of lakes unusable for humans and native aquatic life. Many of these plants are invasive, that is, they spread aggressively, outcompeting the native species. Some species form floating mats that impede boating, fishing, swimming and clog water intakes for irrigation and electrical generation. Thick mats also reduce oxygen content and degrade water quality for fish and other aquatic organisms. Why do we as pond keepers need to be aware of these plants? Many infestations in the wild are the result of plants that have escaped cultivation in water gardens or aquariums. Retailers sell prohibited plants in defience of state or federal law. Hobbyists collect prohibited plants, either deliberately or accidentally, from the wild or by trading with other hobbyists. Improper disposal of prohibited plants can cause them to be introduced to local watersheds. The spread of exotic plants is an extreme threat to the native aquatic environment and a potentially dangerous situation.

Extractions: Erich Haber What are invasive Plants? Any plant growing where it is not wanted and where it becomes a nuisance because of its presence in large numbers or because of objectionable attributes is considered to be a weed. These pests tend to grow aggressively in agricultural lands, home gardens, roadsides and other disturbed sites. Some also possess noxious properties that cause allergic reactions or poisoning if contact is made or if they are eaten. The majority of weeds are exotic species having their origins in other countries. There are about 4200 species of vascular plants in Canada (Scoggan 1978-1979). Of this total, about 30% are exotic species whose origins are from other countries and regions with a similar climate. Most of these come from Europe or Eurasia. Their introduction to North America dates from the earliest arrivals of explorers and settlers. These immigrants brought with them a variety of common agricultural weeds stowed as contaminants in natural packing materials, as fodder for livestock, within bags of seeds and in the ballast of the ships transporting them to the New World. Even some of the herbs brought for cooking and medicines and some of their favourite garden ornamentals, in time, were also to become troublesome pests. This invasion of exotics has continued to the present time. There are also native species, however, that are considered to be weeds. The common milkweed (

Extractions: There are a few ways in which tamarisk threatens native species. One way is through the amount of water the plant takes up, i.e. drinks. It sometimes leaves little water for other plants. Tamarisk also seeds "fast and furious". Tamarisk seeds are blown throughout the Wash area and, once they've landed, start growing quickly. As these species become increasingly prevalent, they push other species right out of their homes.
Extractions: In order to regulate the importation, movement, sale, possession, cultivation and/or distribution of certain invasive plants. These plants either pose a threat to the Vermont environment or are already negatively impacting waterways and natural areas in the state. Many of these plants are becoming such a problem that there is no alternate prevention method. This rule will also prevent plants not yet found in Vermont from being introduced, and will protect the state from the many environmental, agricultural, recreational, and/or economical problems associated with their presence. As defined by the Noxious Weed Quarantine Rule, noxious weeds are: any plant in any stage of development, including parasitic plants whose presence whether direct or indirect, is detrimental to the environment, crops or other desirable plants, livestock, land, or other property, or is injurious to the public health. Noxious weeds are generally exotic, invasive species that are very good at establishing in natural areas and then out-competing native species. Once established, these weeds take over and can greatly decrease the amount of biodiversity in an area, therefore reducing the native species and altering the entire ecosystem.

Complete Literature Citation for Part I and Part II Expand species list to include invasive species Expansion of act administrative responsibilities The utility of the federal Seeds Act for controlling invasive species in natural habitats is considered minimal (see Section " federal Seeds Act "). Options for Act modification in this section will therefore concentrate on provincial Acts where there is considerably more potential for their use. Below, several options are described for modifying the current provincial Weed Acts to make them suitable for use in controlling invasive species. Some stand independently while others must be applied concurrently for each to be effective. For example, the effectiveness of expanding the number of species on the list will not be significant without increasing human resources to effectively implement the Acts. 5.1 Expand species list to include invasive species
Extractions: Provincial Weed Acts Because the Weed Acts discussed in Section " Provisions of Weed Acts " are not written for the purpose of protecting natural habitats their use may be limited. It is important, however, to determine the extent to which these Acts, already well-established administratively, could be used for this purpose and how they might be updated to be more useful ( Section 5.0 Of the 44 species listed in Part I as invasive, to varying extents, in native upland habitats, five are considered noxious weeds under the federal Seeds Act Table 2 ). Three are classed as prohibited noxious weeds-leafy spurge ( Euphorbia esula ), nodding thistle ( Carduus nutans ), and spotted knapweed ( Centaurea maculosa ); one is a primary noxious weed-Canada thistle ( Cirsium arvense ); and one is a secondary noxious weed-ragweed (

Noxious Species - Injurious, hurtful, harmful,: unwholesome. The extent and continuing spread of exotic and noxious species of plants in Southern California is a serious long-term water resources issue. Several of these species consume far larger quantities of groundwater from soils than native species. The most prominent example is the species Arrundo Donax, also known as giant reed. An example photo is (will be) provided below. It is found throughout California's watersheds along streambeds and consumes from 1 to 5 feet of water more than native plants would in the same environment. It has many negative features for insect and animal habitat (and is an ugly and very aggressive plant, ed.) . In the Santa Ana River Watershed alone a total of 10,000 acres of Arrundo Donax plants were surveyed. The water consumed by these plants is equal to 10,000 to 50,000 acre-feet of water, enough for 80,000 to 400,000 citizens. Taken together with other watersheds in Southern California this plant may have displaced over 50,000 acres of native plants, along with a proportionately greater use and waste of water. This page is perhaps more important than the page related to endangered and threatened species. Exotic and noxious species need to be identified and banned aggressively in California to preserve our native species and to protect the quantity and quality of our water resources and related infrastructure.
Invasive Weeds invasive, noxious weeds are a key constraint to agricultural productivity and environmental Anestimated 5,000 alien plant species have become established in http://www.ppru.cornell.edu/weeds/Invasive_weeds.htm
Extractions: Plant species become a problem when they out-compete surrounding vegetation and form dense stands of a single species as illustrated by purple loosestrife. Many of the species able to usurp their environment do so because they have no insect or diseases that hold them in check. These plants, these weeds, generally are introduced and are referred to as exotic invasive species. ARS has a long history of research to find ways to rebalance weeds that has become highly invasive. Examples include water hyacinth, alligatorweed, leafy spurge, klamath weed and musk thistle. Researcher went back to the native home of the target weed and studied factors which had evolved as specific controlling mechanisms. These insects, diseases and nematodes are studied to determine efficacy and host specificity. Organisms that pass strict requirements are documented for examination by an interagency committee. This committee makes recommendations based on the data. Canada and Mexico are also consulted for approval. An agreement for introduction results in the organism being collected and sent into a US quarantine facility where further studies are conducted before releases are made anywhere in North America. go away.

Extractions: Regional Inventory and Assessment of Noxious Weeds The objective of earth-surface surveys is to accurately identify and delineate areas with attributes of interest, such as nonnative invasive species populations or wood resources. Questions usually addressed are those of what, where, and how much exists. Scientists and managers conduct inventories to predict areas likely to contain the attributes, how they got there, and the ways they interact with their environment. All such information is used to develop, implement and evaluate management plans; assess economic impacts, and increase public awareness and education about needed control, planning, and research efforts. Repeated inventories monitor attributes over an extended time period. With noxious plant species, inventories provide information about the geographic range of species populations and the density of infected resources. A sample-based inventory is applied over a large area to estimate attributes with a stated range of confidence, and baseline information for estimating change over time. An Operational Inventory (OI) estimates populations or resources within a given management area so that effective treatments can be accomplished. A
