Impacts and Recovery from Severe Tropical Cyclone Yasi on the Great Barrier Reef

Full recovery of coral reefs from tropical cyclone (TC) damage can take decades, making cyclones a major driver of habitat condition where they occur regularly. Since 1985, 44 TCs generated gale force winds (≥17 metres/second) within the Great Barrier Reef Marine Park (GBRMP). Of the hurricane strength TCs (≥H1—Saffir Simpson scale; ≥ category 3 Australian scale), TC Yasi (February, 2011) was the largest. In the weeks after TC Yasi crossed the GBRMP, participating researchers, managers and rangers assessed the extent and severity of reef damage via 841 Reef Health and Impact Surveys at 70 reefs. Records were scaled into five damage levels representing increasingly widespread colony-level damage (1, 2, 3) and reef structural damage (4, 5). Average damage severity was significantly affected by direction (north vs south of the cyclone track), reef shelf position (mid-shelf vs outer-shelf) and habitat type. More outer-shelf reefs suffered structural damage than mid-shelf reefs within 150 km of the track. Structural damage spanned a greater latitudinal range for mid-shelf reefs than outer-shelf reefs (400 vs 300 km). Structural damage was patchily distributed at all distances, but more so as distance from the track increased. Damage extended much further from the track than during other recent intense cyclones that had smaller circulation sizes. Just over 15% (3,834 km2) of the total reef area of the GBRMP is estimated to have sustained some level of coral damage, with ~4% (949 km2) sustaining a degree of structural damage. TC Yasi likely caused the greatest loss of coral cover on the GBR in a 24-hour period since 1985. Severely impacted reefs have started to recover; coral cover increased an average of 4% between 2011 and 2013 at re-surveyed reefs. The in situ assessment of impacts described here is the largest in scale ever conducted on the Great Barrier Reef following a reef health disturbance.

American Samoa’s island of giants: massive Porites colonies at Ta’u island

[Extract] One of the largest and oldest single hermatypic coral colonies known is a massive Porites coral located on the southwest corner of Tau island (14°15S, 169°30W) in the Manua group of American Samoa. The coral is believed to be Porites lutea based on colony and corallite morphology; however, Porites taxonomy is notoriously difficult and recent genetic work has revealed surprising levels of cryptic diversity (Forsman et al.2009). Small (1 cm) cores were collected for genetic and microscopic work, and to determine skeletal density. DNA sequence for mitochondrial (COI, COIII) and nuclear (ITS region) markers were deposited in GenBank (accession numbers ITS-FJ416523-6, mt COI-FJ423967, and mt control FJ427369), and skeletal voucher specimens have been deposited at the Bishop Museum (SC4164).

Advances in monitoring the human dimension of natural resource systems: an example from the Great Barrier Reef

The aim of this paper is to demonstrate the feasibility and potential utility of decision-centric social-economic monitoring using data collected from Great Barrier Reef (Reef) region. The social and economic long term monitoring program (SELTMP) for the Reef is a novel attempt to monitor the social and economic dimensions of social-ecological change in a globally and nationally important region. It represents the current status and condition of the major user groups of the Reef with the potential to simultaneously consider trends, interconnections, conflicts, dependencies and vulnerabilities. Our approach was to combine a well-established conceptual framework with a strong governance structure and partnership arrangement that enabled the co-production of knowledge. The framework is a modification of the Millennium Ecosystem Assessment and it was used to guide indicator choice. Indicators were categorised as; (i) resource use and dependency, (ii) ecosystem benefits and well-being, and (iii) drivers of change. Data were collected through secondary datasets where existing and new datasets were created where not, using standard survey techniques. Here we present an overview of baseline results of new survey data from commercial-fishers (n = 210), marine-based tourism operators (n = 119), tourists (n = 2877), local residents (n = 3181), and other Australians (n = 2002). The indicators chosen describe both social and economic components of the Reef system and represent an unprecedented insight into the ways in which people currently use and depend on the Reef, the benefits that they derive, and how they perceive, value and relate to the Reef and each other. However, the success of a program such as the SELTMP can only occur with well-translated cutting-edge data and knowledge that are collaboratively produced, adaptive, and directly feeds into current management processes. We discuss how data from the SELTMP have already been incorporated into Reef management decision-making through substantial inclusion in three key policy documents.

The role of Great Barrier Reef tourism operators in addressing climate change through strategic communication and direct action

ABSTRACT The projected decline in reef health worldwide will have huge repercussions on millions of stakeholders depending upon coral reefs. Urgent action is needed to sustain coral reefs into the future. Tourism operators are recognised as stewards of Australias Great Barrier Reef (GBR), a World Heritage Site, and are taking action on climate change, through their business practices and by engaging guests with interpretation and targeted messages. Yet little is known about how tourism operators along the GBR perceive climate change, or what actions they believe are most effective to address climate change impacts on the GBR. We describe a set of semi-structured interviews with 19 tourism operators in the Whitsundays and Cairns, the most popular tourism destinations along the GBR. Using a thematic analysis to code and report patterns within the data, we show tourism operators recognise the threat of climate change and strongly support increased action to address it. Most respondents are hesitant to engage their guests about climate change despite acknowledging an interest, expertise, and responsibility to do so. Understanding the barriers preventing tourism operators from addressing climate change is an important step towards helping them, and the tourists visiting the region, take action to protect the GBR.

The dependency of people on the Great Barrier Reef, Australia

ABSTRACT Understanding how people are dependent on Large Scale Marine Protected Areas (LSMPAs) is important for understanding how people might be sensitive to changes that affect these seascapes. We review how resource dependency is conceptualized and propose that it be broadened to include cultural values such as pride in resource status, scientific heritage, appreciation of aesthetics, biodiversity, and lifestyle opportunities. We provide an overview of how local residents (n = 3,181 face-to-face surveys), commercial fishers (n = 210, telephone surveys), and tourism operators (n = 119 telephone surveys) are potentially dependent on the Great Barrier Reef (GBR), a region currently experiencing significant environmental, social, and economic change. We found that commercial fishers and tourism operators were dependent not only financially on the GBR, but also because of their age, years in the industry and region, lack of education, and the number of dependents. These stakeholders lacked flexibility to secure alternative employment. All stakeholder groups, regardless of economic imperatives, were dependent on the GBR because of their cultural connections. We propose that resource dependency also provides an umbrella concept to describe the cultural services provided by an ecosystem, which can be described through place-based dependence and place-identity.

On the relationship between attitudes and environmental behaviours of key Great Barrier Reef user groups

© 2018 by the author(s). Urgent action is required to address threats to ecosystems around the world. Coral reef ecosystems, like the Great Barrier Reef (GBR), are particularly vulnerable to human impacts such as coastal development, resource extraction, and climate change. Resource managers and policymakers along the GBR have consequently initiated a variety of programs to engage local stakeholders and promote conservation activities to protect the environment. However, little is known about how and why stakeholders feel connected to the GBR nor how this connection affects the proenvironmental behaviors they undertake. We present the results of 5891 surveys and show that the attitudes that residents, tourists, and tourism operators have about the GBR are closely tied to the behaviors and activities they take to protect the environment. Our findings suggest that the responsibility, pride, identity, and optimism that people associate with the GBR are significantly correlated to several proenvironmental behaviors, including recycling, participation in conservation groups, and certain climate change mitigation activities. Respondents who feel the strongest connection to the GBR take the most action to protect the environment. Tourism operators who strongly identify with the GBR take more action to protect the environment than those who do not. Encouraging individual identification with the GBR via targeted messages and engagement campaigns may assist not only in GBR conservation, but a wider sustainability movement as well. A better understanding of the individual attitudes and beliefs held by local stakeholders is a key first step toward effective communication to influence conservation activities.
