It provides background context to these research areas and a list of published reports and journal papers, and unpublished reports and theses that are outputs from NSW Marine Parks Authority research projects. It does not include the broader published literature that has been used to examine these issues across NSW marine parks. The primary criterion for establishing marine parks in NSW is that they contain a comprehensive, adequate and representative selection of marine biodiversity. Comprehensiveness refers to the extent to which the full range of ecosystems and habitats in and across all bioregions are included in marine parks; adequacy is the degree to which the size, boundaries and location of marine parks are adequate to maintain biodiversity and ecological patterns and processes, particularly in relation to the ability to manage impacting activities; and representativeness is the extent to which marine parks reflect the range of biological diversity of communities within ecosystems and habitats. Scientific Audit of NSW Marine Parks: Biodiversity and ecological processes 1 To ensure the above criteria are effectively met in zoning marine parks, information on biological diversity (and their effective surrogates) and ecological processes are included in the planning process. Initial broadscale biodiversity assessments as part of the NSW marine park planning process were presented in a series of bioregional assessments (Breen et al. 2004, 2005a, b). These included an assessment of comprehensiveness and representativeness, ecological importance, condition and vulnerability. Information on the distribution and extent of estuarine macrophytes (seagrass, mangroves and saltmarsh) and shallow nearshore reef and sand habitats throughout NSW were included in the bioregional assessments. In 2004 an acoustic seabed mapping program was implemented by the NSW Marine Parks Authority to provide information on the extent, distribution and structure of seabed habitats throughout continental shelf waters of NSW. Since then marine habitat mapping has been a core research and monitoring program undertaken throughout the state to support the declaration and zoning of marine parks. Over the past seven years approximately 760 km2 of seabed habitats in marine parks have been mapped, and another 500 km2 in NSW coastal waters outside marine park boundaries. An additional 570 km2 of existing seabed data have also been incorporated into digital layers of bathymetry and seabed habitats (Jordan et al. 2010). These have been combined with the estuarine map layers developed by NSW DPI to produce the first 1:25,000 seabed map series for NSW. In addition, broad-scale bathymetry and sediments maps have recently been completed for the entire NSW continental shelf. Overall, the MPA has collected and collated extensive fine-scale and coarse-scale spatial information on seabed habitats that has been used directly to examine zoning options that most effectively represent the patterns of biodiversity surrogates in NSW marine parks. Combined with targeted seabed assemblage surveys from diver and towed video, as well as species diversity surveys using divers, baited underwater video and grabs, the MPA has tried to ensure that marine park locations and zones represent the biodiversity of NSW waters. A range of specific biodiversity surveys have been conducted in recent years that build on other surveys conducted before the current zoning plans commenced, and complement projects conducted within the marine parks by external research providers (e.g. university projects, CERF Marine Biodiversity Hub, IMOS). This includes the recent high resolution Autonomous Underwater Vehicle surveys of continental shelf seabed habitats that are examining macroalgal and sessile invertebrate composition in various marine park zone types. An important component of the biological diversity in marine ecosystems is reef-associated fishes, as they have ecological, social, cultural and economic value. Information on the spatial patterns of fish community composition is combined with seabed habitat maps. For example, surveys of the Solitary Islands Marine Park have focused on the composition of shallow and intermediate-depth reef fishes (Malcolm and Smith, 2010; Malcolm et al. 2010a, b, 2011). Other components of biodiversity have been examined in a number of marine parks, including reef and soft-sediment macroinvertebrates and algae. Reviews and field assessments of important marine faunal and floral groups have also been conducted (Cardno Ecology Lab, 2010; Davis et al. 2010; Jordan et al. 2010). The assessment of threatened, protected and endemic species is also a priority research area, and a number of projects have examined this issue over recent years. This includes the establishment of a monitoring program for black cod in a number of marine parks and assessment of the population of endemic species on Lord Howe Island and assessment of risk. Ecological processes represent the interactions within and among species, and encompass the numerous key processes within an ecosystem such as predation, grazing, recruitment, behaviour and movement across the entire life cycles of the species involved. Measuring a range of ecological processes across marine park zones is an important component of the research program, and has been targeted primarily at issues relating to habitat associations, Scientific Audit of NSW Marine Parks: Biodiversity and ecological processes 2 measuring changes in assemblage composition in relation to zoning (e.g. Edgar and StuartSmith, 2009), and large scale processes of biological oceanography and connectivity (e.g. Malcolm et al. 2011; Coleman et al. 2011a). Assessment of species and assemblage interactions has primarily been conducted on shallow reefs using visual census techniques to assess numbers and species of fishes on reefs and changes through time of macroalgae cover and benthic invertebrate grazers (such as the urchin Centrostephanus rodgersii). A number of current research programs, such as the monitoring of intermediate depth reefs using Baited Remote Underwater Video are collecting long-term data to examine this issue. Understanding connectivity patterns of species helps predict how they will respond to such changes as habitat loss and variations in oceanic currents due to climate change, and whether they can recover from such perturbations. Several current research projects are examining these issues using genetics and oceanographic modelling (e.g. Coleman et al. 2011b). Such research can also assist with zoning plans by understanding how pre and postsettlement factors such as dispersal and migration relate to spatial arrangements of organisms. The recent deployment of acoustic tracking technology in marine parks aims to examine the scale of movement for key fish and shark species, and will provide key information required to assess the adequacy of zones for maximising protection for such species.
