II COASTAL PLANNING AND MANAGEMENT MANUAL Foreword The coast is important to the lifestyle and livelihood of the people of Western Australia. It is a significant asset that contributes to the environmental, economic, social and cultural fabric of the State. The majority of Western Australians choose to live close to the coast. An even greater proportion chooses coastal locations as tourism and recreation destinations, attracted to the many and varied natural coastal assets on offer. But there is also demand for access to the coast from fishing and aquaculture industries, ports and shipping, and mineral exploration. The coast is under increasing pressure from human activity and its conflicting user demands. Coastal planning and management that is based on sound principles can help to resolve these conflicts and mitigate the impacts of how we utilise our coastal resources. In addition to the coastal planning and management work done by government, over 160 community groups are actively engaged in coastal management around Western Australia. Production of this manual seeks to acknowledge the significance of this contribution through the provision of practical information on coastal planning and management. Information in the manual focuses on guiding development and implementation of coastal management projects in response to local pressures. It has largely been compiled thanks to the skills and experience of the coastal community, and seeks to promote the exchange of ideas within that same community, for better outcomes.
