Engagement by New South Wales Marine Estate Users with and Evaluation of Communication Approaches to Strengthen Biosecurity Practices

Abstract

Marine environments are susceptible to the impact of human boating activities that facilitate incursions of marine pests and diseases, including invasive alien species (IAS). Movement and maintenance of recreational boats is largely unregulated, and if boats are improperly maintained, movement of IAS on these unmaintained boats can impact livelihoods and food security. This project evaluated the impact of communication and engagement interventions implemented within the New South Wales marine estate that aimed at strengthening biosecurity practices of small to medium permanently moored boat owners/managers. A mixed method approach using a cross-sectional survey and interviews was used to evaluate exposure to and impact of the communication and engagement strategies, including Facebook images and videos on biosecurity practices in the NSW marine estate. Participants expressed a desire for information about marine pests and diseases via electronic newsletters (43.3%, n = 58) and of the survey participants who used Facebook, the majority (90.2%, n = 119) had not seen the communication interventions. Interview participants identified some infrastructural barriers to keeping their boats clear of biofouling despite a desire to do so. Overall, most participants showed awareness of and wanted to help protect waterway health, which supports ongoing efforts by New South Wales Department of Primary Industries Agriculture and Biosecurity Aquatic unit to improve biosecurity practices of all marine estate stakeholders and informs future development of aquatic biosecurity communication and engagement strategies.
