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.

Extractions: 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 Dyers Woad ( Isatis tinctoria Dyers 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."
Extractions: by George Wooten and Marlene Renwyck Abstract Invasive species management on public lands is a complex issue which is currently being approached in a variety of ways. Recent efforts to eradicate weeds on National Forests have been costly and sometimes ineffective. Controversy has erupted over the use of herbicides and their potential for harm to health and the environment. This study critically examines the basis of current plans, policies and programs for managing invasive species on federal public lands, along with a presentation of alternative solutions. To successfully control invasive species, sound policies must be in place, which require clearly stated, measurable goals and objectives based on an understanding of the biology and ecology of invading species. In responding to invasions on public lands, managers need to shift their approach from short-term reduction efforts to flexible approaches that treat the causes of invasions rather than the symptoms, while placing more emphasis on prevention and monitoring. Document Conventions This document provides the background and rationale for recommended changes and improved implementation of objectives, policies and programs dealing with the management of invasive species. Topics are described in detail along with illustrative case examples. Emphasis is placed on describing the effects of herbicides on lands administered by the Forest Service, although in many instances, discussions also apply to pesticides in general and other land ownerships.

Extractions: Weeds Noxious weeds are non-native plants introduced to North America from Europe and Asia. These plants have spread at an alarming rate because, unlike native species, there are no native insects, fungi, or diseases to control their growth and spread. Noxious weeds destroy wildlife habitat and forage, threaten endangered species and native plants, increase erosion and groundwater loss, and prevent recreational activities. Estimates are that noxious weeds have invaded approximately 17 million acres of public rangelands in the West - more than quadrupling their range from 1985 to 1995. In northern California, yellow star thistle expanded its range from 1 million acres in 1981 to 10 million in 1997. Everyone can help control noxious weeds. The Western Shasta RCD is just one of many groups mounting an effort to control and prevent the rapid spread of noxious weeds. You can help by controlling weeds manually, by hand pulling or other mechanical means, or chemically by the application of herbicides. When using herbicides, always read the labels thoroughly and follow the instructions. We strongly advise using gloves and safety glasses when using any herbicide or even when pulling weeds, since many have spines or substances that can irritate the skin.
