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 (

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: February 3, 1999 MEMORANDUM TO: Resource Management Committee, Public Lands Council, Interested Parties FR: Tom McDonnell RE: Presidential Executive Order on Invasive Alien Species While noxious plant and animal species like Russian knapweed, leafy spurge, nutria and the gypsy moth are and should be of concern to agriculture and the American public, this executive order goes far beyond the control of noxious species. As defined within the executive order, dogs, cats, wheat, barley, rice, and domesticated livestock could be considered invasive alien species. Federal agencies under section 2 of the executive order are directed to 1) prevent the introduction of such species; 2) control populations of such species, and; 3) provide for restoration of native species and habitat conditions in ecosystems that have been invaded. This executive order has major ramification not only on agriculture within the United States, but also on the daily lives of every American. The first paragraph of the executive order on invasive species directs federal agencies "to prevent the introduction of invasive species and provide for their control and to minimize the economic, ecological, and human health impacts that invasive species cause…" The definitions under Section 1 are critical to understanding the far reaching scope of this statement. To quote the executive order, ""alien species" means, with respect to a particular ecosystem, any species including its seeds, eggs, spores, or other biological material capable of propagating that species, that is not native to that ecosystem." Because the executive order fails to define domesticated species, most agricultural crop and animal species would clearly fall within the definition of alien. Domesticated pets, many houseplants, and Kentucky bluegrass used in most lawns and golf courses would also be defined as alien species under this executive order. With the administration's preoccupation with indigenous people, some races of man may also be considered alien.

Invasive species of plants and animals are displacing and destroying native species all across our National Forest lands. There unwelcome invaders, which are native or non-native plants, animals, insects and pathogens (disease causing bacterium or fungus), can cause ecological and economic harm as well as create human health issues. Some invasive species, such as the tamarisk in Utah and Arizona, were introduced on purpose to control erosion, while others, such as the Asian longhorn beetle were accidentally introduced in wood packing crates from China. Today, invasive species cover 3.5 million acres of national forest land and 133 million acres in all ownership nationwide.

Extractions: The Ecological Problem Invasive species are a part of the flora of British Columbia. They are species that have become abundant and widespread in the landscape to such a degree that they replace or swamp the natural species assembly in an ecosystem, and cause havoc with ecosystem function. There are often economic implications associated with invasives, such as in rangeland areas where they replace important browse plants. They are usually species that are alien or introduced to a region, often originating in Europe or Asia. The invasive species problem is a complex one. Invasive species affect food sources for wildlife, can influence pollinator availability, and can crowd out native species directly. We are now seeing dramatic changes in bird populations, elk herds, reindeer herds, and other wildlife as a result of the replacement of native species by alien species. While some animal species can adapt and feed on alien food sources, many cannot. A comprehensive discussion on Battling the Alien Invasion!

Extractions: Guide to Monitoring Exotic and Invasive Plants 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 (

Invasive Species Control: The Oregon legislature established an invasive species council in 2001 to promote reporting of invasive species sightings, increase education about invasive species, and provide grants or loans for eradicating new introductions of invasive species. The Oregon Progress Board established a new benchmark, the "number of nuisance invasive species," for measuring the threat of invasive species to biological diversity in Oregon. The Willamette Restoration Initiative's strategy recommends, "prevent[ing] the introduction and control[ing] the spread of the most harmful invasive species" as a critical action in restoring the Willamette River basin.

Extractions: Background On February 3, 1999, President Clinton signed Executive Order 13112 (E.O.) which calls on Executive Branch agencies to work to prevent and control the introduction and spread of invasive species. Nonnative flora and fauna can cause significant changes to ecosystems, upset the ecological balance, and cause economic harm to our Nations 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. Transportation systems can facilitate the spread of plant and animal species outside their natural range, both domestically and internationally. Those species that are likely to harm the environment, human health, or economy are of particular concern. The Department of Transportations efforts to prevent the introduction and spread of invasive species are consistent with: (1) the Departments strategic goal of protecting the natural environment, service, and teamwork; (2) statutory mandates to protect against aquatic invasive species; (3) the Departments active participation on interagency committees such as the Federal Interagency Committee for Management of Noxious and Exotic Weeds (FICMNEW), the Native Plant Conservation Initiative (NPCI), the Interagency Ecosystem Management Task force, and the Interagency Working Group on Endangered Species; and (4) the 1994 Presidential Memorandum on Environmentally and Economically Beneficial Landscaping Practices. The U.S. Department of Transportation has traditionally been in the forefront of national efforts to prevent and control the introduction of invasive species. On April 22, 1999, Secretary Slater issued a

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.
