Cultural ecosystem services have received increasing attention in land/marine use planning but remain poorly known, expressed, and utilised in planning processes. Progress in marine spatial planning requires better information regarding the full range of values and benefits received from ecosystem services, including cultural ecosystem values. This paper reports on an online Public Participation GIS (PPGIS) study that collected spatially explicit information on cultural ecosystem values in the remote Kimberley coastal region in northwestern Australia. The coastal zone – 20 km landwards and seawards – was found to be highly valued with values disproportionally located 0–2 km onshore. The number of value markers placed was related to tenure, access (i.e., density of tracks), population density, and geomorphology. Methodologically, Public Participation GIS describes the location and extent of values providing for the exploration of relationships between values and other planning features such as tenure and coastal access. Inclusion of such information in marine spatial planning and policy formulation can contribute to more thoughtful and inclusive decisions regarding the future of coastal zones. The use of internet-based Public Participation GIS is particularly useful for long, remote coastlines with widely dispersed stakeholder interests where other methods such as interviews and workshops are not feasible.

Planning and management for marine and coastal areas is often contentious, with competing interests claiming their preferences are in the ‘public interest’. Defining the public interest for marine and coastal areas remains a wicked problem, however, resistant to resolution. A focus on more tangible ‘public values’ offers an alternative for policy and planning in specific contexts. However, ambiguity surrounds who or what constitutes the ‘public’, with stakeholder engagement often used as a proxy in marine and coastal research. In this study, the outcomes of participatory processes involving the public from diverse backgrounds and geographical locales were explored. A public participation GIS (PPGIS) survey was undertaken in the remote Kimberley region of Australia to identify the spatial values and management preferences for marine and coastal areas. Similarities and differences between the volunteer public (n = 372) and online panel respondents (n = 206); and for the volunteer public only, differences between residents (n = 118) and non-residents (n = 254) were assessed. Online panelists evidenced lesser quality mapping data and did not provide a reliable means of accessing ‘public’ values. Residents were more likely to map general recreational and recreational fishing values while non-locals were more likely to map biological/conservation and wilderness values. Overall, residents and non-residents were more alike than dissimilar in their mapping of values and management preferences, suggesting that the need to preference local views may be overstated, although there may be differences in policy priorities. Future research should focus on the breadth and representativeness of stakeholder interests to access the views of wider society and hence public values, rather than current approaches where local interests are often the primary focus of participatory stakeholder engagement.

This paper examines environmental characteristics of a remote coastline adjacent to an extensive fringing coral reef in a World Heritage Area impacted by tourism and extensive use of off-road vehicles. Hyperspectral remote sensing imagery combined with field validation were used to map and characterise the 300-km coast including shore type, land cover and vehicle track footprint. Adjacent to Ningaloo Marine Park, only sparse coastal vegetation cover was present. However, there exists an extensive (1256 km) vehicle track network with the highest densities near accommodation nodes and sandy beaches (over 65% of tracks). Areas managed for conservation had fewer tracks and the lowest track density (0.3 km/km2) compared to pastoral stations (∼1.9 km/km2). The cumulative lengths of tracks were highest on pastoral stations used for livestock grazing, coastal access and camping (945 km out of the total of 1256 km of tracks). The fragility of the arid landscape and this assessment of off-road vehicle impact obtained through detailed mapping of tracks indicate the need for management measures to mitigate the damage and cope with the increasing numbers of visitors.

Being able to accurately locate and describe recreational use within marine parks is essential for their sustainable management. Given the difficulty in accessing many marine parks, as well as their large size, the surveys to obtain these much-needed data are often logistically challenging and expensive. Aerial surveys are one potential method for obtaining accurate, timely data and this paper details the design for one such survey conducted in the Ningaloo Marine Park, off the northwestern coast of Australia. Ningaloo has been nominated as a world heritage site and the fringing coral reef that forms the centrepiece of the Marine Park extends for 300 km along the coastline. The survey involved 34 temporally stratified flights conducted over a 12-month period. All vessels and people were geo-referenced and where possible, their activities were recorded, providing data that clearly illustrates dramatic expansions and contractions in recreational use. Not only does the spatial extent of use expand in the peak visitor season (April–October), the density of use correspondingly increases. High densities of recreational activity in the Park’s waters were accompanied by increased numbers of vehicles, camps, boat trailers and boats on the adjacent shoreline. Aerial surveys proved to be an effective method for rapidly obtaining recreational data with high spatial accuracy. Such a method has broad applicability to marine parks as it provides comprehensive data to benchmark existing recreational use, as well as monitor future changes in activity patterns, which are essential for the informed management that must underpin sustainability efforts.
