Back to top State-prohibited Wildflower Seed Species A completely separate grouping of problem plants is listed by each state, usually in their seed statutes. These state laws have been around for a very long time, and they remain an amalgam of old agricultural and livestock protection rulings plus newer environmental concerns. Prohibiting seeds (and/or plants) from a state (or country, for that matter) have always been a somewhat efficient method of control, since seed companies shipping across state lines can be held accountable for enforcing the regulations.

Back To Feature Stories Index Noxious Species, A Focus For Reclamation Since its introduction by east coast nurseries the early 1800s, the plant is now found in half of the country. It grows ferociously along rivers, can tolerate soils high in both salt and alkaline, and produces thickets of trees and shrubs nearly twenty feet high. It out-competes native plants with deep tap roots that intercept water tables and disrupt the surrounding aquatic system. An invasive species can enter the environment in one of three ways: (i) deliberate introductions, (ii) species imported for a limited purpose which then escape and, (iii) accidental introduction. The Zebra Mussel is an example of accidental introduction. The finger-sized crustacean, native to the Caspian Sea , came to the Great Lakes via ballast water from transoceanic vessels around 1988. Since then, it has escaped and spread to all of the Great Lakes and many of the lakes and river systems of the Northeast. They can attach to anything, including each other, to clog pipes and engines. Erika Zavelta is with the Department of Biological Sciences at Stanford University . Her research on Tamarisk focuses on impacts of human changes on the ecosystem. She says eradication is possible, and points to successful projects in central Texas . Through a program of cutting, root plowing, application of environmentally safe herbicide, rearing and replanting of native species and monitoring over a 20-year period, she says benefits would keep pace with control costs and afterwards, would accrue indefinitely.

GOVERNOR DIRK KEMPTHORNE Remarks to Idaho Council on Industry and the Environment Invasive Species and Noxious Weeds 4th Floor Gold Room, Idaho State Capitol January 29, 2003 (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.

52. Galapagos Invasive Species: Plants invasive alien plants in the Galapagos Islands, including plant species invasivein the Galapagos Islands, Galapagos invasive species noxious weeds http://www.hear.org/galapagos/invasives/topics/management/plants/

Galapagos Invasive Species: Noxious weeds Español Glossary Invasives home page Galapagos is typical of oceanic islands in having a very small native flora - only some 500 vascular plant species, of which 180 are endemic. These arrived or evolved over the 3 million years or so of the existence of the present Galapagos islands, at a rate of about one species arriving every 10,000 years. In striking contrast, more than 640 vascular plant species have been introduced by people to Galapagos, about 90% of them deliberately, since the discovery of Galapagos by humans, i.e. at a rate of about 1.3 species per year. The 90% are useful plants, including fruit, vegetables and other crops, timber trees, medicinal plants and ornamentals. The relatively few accidentally introduced plants are mostly pan-tropical or European weeds of disturbed areas, which have often spread widely in Galapagos because of the open, “naturally disturbed” character of much of the environment in the archipelago. However, the accidentals have rarely been the cause of major problems for the native biota, whereas many of the plants introduced for cultivation have escaped and are now threatening native species and habitats.

ORGANIZING IN MISSISSIPPI AND THE MID-SOUTH INVASIVE SPECIES ALLIANCE. John Byrd, Mississippi State University ( jbyrd@pss.msstate.edu ABSTRACT We propose to develop an alliance of federal, state, and local government agencies, nongovernmental organizations and concerned citizens focused on the early detection and management of invasive noxious species in Mississippi-the Mississippi Invasive Species Alliance (MS ISA). Also, through funding from the US Geological Survey, we propose to develop and implement a task force of federal, state, and local government agencies, nongovernmental organizations and concerned citizens focused on the early detection and management of invasive noxious species in mid-southern states-The Mid-South Invasive Species Alliance (MSISA). The organization will be tiered, with coordination at both the state and regional level. Our target states include Alabama, Arkansas, Louisiana, Mississippi, and Tennessee. Mississippi Invasive Species Alliance We propose to develop a Mississippi Invasive Species Alliance with the primary purposes of coordinating existing programs and developing a data-sharing network for the occurrence of invasive species, and secondarily to increase the acquisition of funding and efficiency of fund utilization to deal with Mississippi problem invasive species. We propose a tiered approach, with an Executive Council of decision-makers from major agencies or organizations, a Technical Steering Committee, and an Advisory Committee composed of those interested in participating. The alliance will coordinate the sharing of data, act as a clearing house for locations of invasive species in the region, facilitate information exchange at the appropriate federal level, and act to coordinate funding of regional management efforts.

featuring developments in federal highway policies, programs, and research and technology Editor's Notes Along the Road Internet Watch Recent ... Home Beware of Invasive Species The following is adapted from several Department of Transportation sources, primarily Roadside Use of Native Plants, a handbook published by the Federal Highway Administration. Roadside Use of Native Plants provides state-by-state references on the use of native plants and how they can be used to benefit highway projects. Beware of invasive species. No, we are not talking about aliens from outer space. Invasive species are plants and animals that are introduced into new areas in which they are not among the native flora and fauna, and because they no longer face the natural enemies or competition from their place of origin, they spread or reproduce prolifically. Invasive species can be a very, very big problem. Non-native species can cause significant changes to ecosystems, upset the ecological balance, and cause economic harm to our nation's agricultural and recreational sectors. For example, introduced plants, such as kudzu in the southeastern states and purple loosestrife throughout the country, have choked out native plant species and consequently have altered wildlife and fish habitat. Zebra mussels introduced into the Great Lakes in the ballast water of cargo ships have colonized water pipes, boat hulls, and other surfaces, wreaking havoc on water systems, transportation, and native shellfish. Each year, approximately $23 billion nationwide is lost to the effects of invasive plants on agriculture, industry, recreation, and the environment. An estimated 1860 hectares (4600 acres) of land are invaded daily by invasive plants.

60. Weeds are placed into two major groups, noxious and invasive. noxious weeds areplant species that tend to be especially injurious to public health, crops, http://faculty.weber.edu/sharley/AIFT/weeds.htm

Weber State University Department of Botany Antelope Island Field Trip Noxious and Invasive Weeds of Antelope Island What is a Weed? Weeds are defined as plants out of place or as "a plant that interferes with management objectives for a given area of land at a given point in times" (J.M. Torell) Weeds, plants that pose a threat to the welfare of a community, are placed into two major groups, noxious and invasive. Noxious weeds are plant species that tend to be especially injurious to public health, crops, livestock, or other properties. Invasive weeds are plant species that have the potential to spread rapidly and become noxious. One of the most spectacular displays of spring wild flowers along the Wasatch front is provided by the weed species of plant called Dyer’s Woad ( Isatis tinctoria Dyer’s Woad is a prime example of the problems faced by land managers who deal with introduced plant and animal species. All states in the U.S. deal with weed problems and have Weed Boards managed by the States' Departments of Agriculture, with authority and responsibility to control weeds given to each county under the direction of the County Weed Supervisor. Our field trip will take us to Antelope Island State Park. It is the home of one the largest publicly owned herds of buffalo in the United State that depend on the vegetation of the Island for food. It, too, has its problems with weeds as described by the Weed Management of Antelope Island 2001: "Noxious weeds are a vegetative wildfire raging out of control. However, unlike a wildfire, noxious weeds spread silently through the years and by the time we realize there exists a problem, it is often too late to eradicate the invader. We then are left to manage around these species and spend large sums of money to simply keep them at bay."
