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.

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.

Remote sensing is a useful tool for detecting change over time.We introduce a hybrid change-detection method for forest and protected-area vegetation and demonstrate its use with two satellite images of Golestan National Park in northern Iran (1998 and 2010). We report on the advantages and disadvantages of the hybrid method relative to the standard change-detection method. In the proposed hybrid algorithm, the change vector analysis technique was used to determine changes in vegetation. Following this, we used postclassification comparison to determine the nature of the changes observed and their accuracy and to evaluate the effects of different parameters on the performance of the proposed method. We determined 85% accuracy for the proposed hybrid change-detection method, thus demonstrating a method for discovering and assessing environmental threats to natural treasures. © 2014 Society of Photo-Optical Instrumentation Engineers.

Increasing demand from mountain bikers for greater access to riding in National Park Service (NPS) units is driving the need for park managers to seriously look at the impacts from and feasibility of permitting this recreational use. Currently, NPS units that permit mountain bicycling do not have formal mountain bicycling management plans. An analysis of recreational policies and existing research was conducted to identify criteria for effective mountain bicycling management strategies. Criteria were developed for trail selection, establishment, use, closures and rehabilitation. Criteria were also developed for user education, participatory planning and monitoring. This study shows that the NPS needs formal mountain bicycling management plans that focus on the preservation of natural and cultural resources and consider the appropriateness of proposed recreational uses.
