Community-based monitoring of Victoria´s marine national parks and marine sanctuaries

This study investigated community-based monitoring in Victoria’s Marine National Parks (MNPs) and Sanctuaries (MSs) from January to May 2004. The primary aim of this study was to evaluate the potential for community-based monitoring projects to assist in the collection of data for the management of Victoria’s MNPs and MSs. The pilot habitats that were assessed included subtidal reefs at the Merri MS, intertidal reefs at Ricketts Point MS and seagrass beds at Corner Inlet MNP. The three main objectives for this study were to:
 - Develop a template for the monitoring of marine habitats by community groups.
 - Assess the quality and integrity of data collected by community volunteers.
 - Determine a sustainable model for community monitoring of marine habitats.
Three standard operating procedures (SOPs) in the form of a “how to” manual, were developed for each habitat type. The SOPs were adapted from scientifically robust studies and developed in consultation with community volunteer groups by means of field trials. Volunteer feedback assisted in the final SOP design. The SOP will allow Parks Victoria Rangers to develop community-based programs within the parks. The SOPs are accessible as Parks Victoria Technical Series Numbers 16, 17 and 18. Data collected by volunteers across the three habitat sites were assessed and compared to that collected by scientists. It was found that data quality collected by volunteers was dependent on habitat type and the type of measurement the volunteer was required to assess. Volunteer estimation measurements were highly variable across all three habitat sites, compared to quantitative data collection. Subtidal monitoring had the greatest potential for inconsistency in data collection. Intertidal monitoring is the most sustainable of the three habitat monitoring procedures. Sustainability of community-based monitoring programs is dependent on continued support and training by the management authority of Victoria’s MNPs and MSs. For the expansion of the monitoring programs to other MNPs and MSs, the management authority could expand strong relationships with the community volunteer groups.

Range extension of the Millewa Skink Hemiergis millewae in the Murray-Sunset National Park, Victoria

This article reports a range extension for the critically endangered Millewa Skink Hemiergis millewae in Victoria. An individual H. millewae was found approximately 85 km east of its former known range in mature mallee vegetation, near the eastern edge of the Murray-Sunset National Park on 27 March 2007. Site characteristics are described, and a list of other reptile species found at the same site is provided. Further research into the habitat associations and distribution of H. millewae is recommended in order to guide the management of this species.

Sea search : a community-based citizen science monitoring program for Victoria, Australia, Marine National Parks and Marine Sanctuaries

Community involvement in monitoring Victoria’s Marine Protected Areas (MPAs) engages coastal volunteers in looking after their marine ‘front yards”. The Management Strategy for Victoria’s System of Marine National Parks and Marine Sanctuaries dedicates an entire theme to community engagement with core key performance areas. This includes community participation. The Sea Search community based monitoring program was developed in 2003 to engage volunteers in meaningful ecological data collection for future sustainability of Victoria’s MPAs. Deakin University, an academic institute, and Parks Victoria, the management agency for Victoria’s MPAs, through a research partner program, trialled three different habitat monitoring methodologies. The trails assessed volunteer ability to collect scientific data, and social science aspects for their involvement in a community-based monitoring program. Information collected by volunteers, feeds directly into their local MPA management strategies to address issues such as climate change, introduced pests and human impacts and natural ecological variation.

The Sea Search program addresses the two action programmes, Agenda 21 and the Rio Declaration on Environment and Development, created at the United Nations Earth Summit, held in 1992. Both documents highlight the need for community engagement and capacity building for sustainability, health and integrity of the earth. Involvement in the Sea Search program builds the volunteer’s capacity by learning scientific skills, interacting with other like minded community members, and creating relationships with all organisations involved in the delivery of the program. In this regard, Sea Search is a citizen science program involving all sectors in society by promoting public-interest and research for decision making and planning of Victoria’s system of Marine National Parks and Marine Sanctuaries.

Ecology of the freshwater crayfish of the Grampians National Park

The ecology of five species of freshwater crayfish occurring in a variety of habitat types in the Grampians National Park was investigated. The study examined the numbers of each species living in the region, how they interact, when they reproduce, and what they eat. Management and conservation requirements were proposed.

Population structure and life history characteristics of euastacus bispinosus and cherax destructor (Parastacidae) in the Grampians National Park, Australia

Despite being the most widely distributed and cultured freshwater crayfish species in Australia, relatively little is known about the ecology of Cherax destructor outside of captivity. Similarly, few ecological studies have been conducted on the large and threatened stream dwelling Australian freshwater crayfish Euastacus bispinosus. A series of seasonal sampling surveys over two years investigated the population structure, life history and reproductive timing of C. destructor in fire dam habitats, and of E. bispinosus in channel (stream) habitats, in the Grampians National Park in south-west Victoria, Australia. Cherax destructor individuals in the largest size class (50 – 59.95 mm OCL) were not abundant during the study, while those belonging to the 0 – 9.95 mm OCL size class were more frequent in summer than at other times of year, suggesting synchronous recruitment in fire dam habitats. Individuals in the reproductively active mid-size classes were also frequent in summer. For E. bispinosus, sex ratios in spring always favoured females, although there were no clear trends for other times of year. Gravid E. bispinosus females were found in winter and spring throughout the study, and were sexually mature at a smaller size than has previously been reported.

Mislabeling marine protected areas and why it matters : a case study of Australia

As part of international obligations and national policies, most nations are working toward establishing comprehensive, adequate, and representative systems of terrestrial and marine protected areas (MPAs). Assigning internationally recognized International Union for Conservation of Nature (IUCN) protected area categories to these MPAs is an important part of this process. The most recent guidance from the IUCN clearly states that commercial or recreational fishing is inappropriate in MPAs designated as category II (National Park). However, in at least two developed countries with long histories of protected area development (e.g., Canada and Australia), category II is being assigned to a number of MPAs that allow some form of commercial or recreational fishing. Using Australia as a case study, this article explores the legal and policy implications of applying protected area categories to MPAs and the consequences for misapplying them. As the Australian Government is about to embark on potentially one of the largest expansions of MPA networks in the world, ensuring the application of IUCN categories is both transparent and consistent with international practice will be important, both for the sake of international conventions and to accurately track conservation progress.
