A Review of Spartina Management in Washington State, US
Management of non-native Spartina plants including Spartina alterniflora Lois., Spartina anglica C. Hubb and Spartina patens (Ait.) Muhl. in Washington State, U.S. evolved during the 1990s from small-scale field trials to a large-scale integrated pest management program. The development and implementation of the program were significantly hindered by stakeholder conflict, particularly regarding the use of herbicide in estuarine environments. In 1995, Washington State Department of Agriculture was appointed to manage these invasive species. Agency coordination and strategy reviews were undertaken. A wide range of control techniques, including physical removal, mowing and herbicide, were established, with all techniques demonstrating considerable limitations. The combination of mowing and herbicide provided the greatest efficacy but was expensive. Development of biological control options is in progress but will take years to prove effectiveness for Spartina management. Program progress based on existing mapping and efficacy data is difficult to gauge. This program demonstrates that Spartina plants are difficult and expensive to eradicate. Between 1995 and 2000, infestations increased in area by 250%, affecting more than 8,093 ha of intertidal land. During this period, approximately 15% of the infestation was treated annually. Although the program has evolved considerably, substantially increasing knowledge on the management of Spartina, infestations in Washington State continue to present a range of management challenges, including the development of a standardized and integrated mapping procedures, cost-effective control techniques and improvements to stakeholder

This article discusses the challenges of integrating tourism into Canadian and Australian coastal zone management. Comparisons are drawn between coastal and marine tounsm resources in Australia and Canada. The resources considered include the cruise ship industry, recreational boating, fishing, sea kayaking, SCUBA diving and marine wildlife tourism. In the introduction, some of the problems of definition and data are addressed. Tourism is described as an industry, but unlike many traditional industries, the tourism arena consists of a myriad of players and sectors. After the comparison of tourism resources in both countries, the power and politics associated with managing user conflicts in marine areas in British Columbia and Australia are discussed. The third part of the article looks at the challenges of environmental management for coastal and marine tourism; specifically, the article focuses on issues arising from the creation of manne protected areas and the development of sustainable whale watching operations. The authors conclude with two case studies, the cruise industry in Pacific Canada and the recreational fishing industry in Australia
Australia's Antarctic agenda
Australia has had a long connection with, and significant national interests in, the Southern Ocean and Antarctica. The Australian Antarctic Territory comprises 42 per cent of Antarctica's landmass. Australia is not only a claimant state and original signatory to the Antarctic Treaty but has played a significant role in the development of what is termed the Antarctic Treaty System (ATS). This article aims to provide an overview of Australia's key policy interests and government policy goals towards Antarctica, including its commitment to the ATS. In examining key policy objectives we note that despite continuity and development of these objectives, significant changes and challenges have arisen in the period 1984-2006. It is these challenges that will help frame Australia's Antarctic agenda over the next 20 years and beyond
