Understanding deep-sea diversity

Conservation in a time of offshore oil and gas development

What are the challenges and opportunities? KEY MESSAGES: Offshore oil and gas development brings with it a range of challenges and opportunities for marine biodiversity conservation The conservation community should become more actively involved in the earliest planning and exploration phases of oil and gas extraction Environmental decision-support tools can be used to explicitly incorporate […]

Should we protect highly threatened habitats or safe habitats?

Risk it or play it safe? KEY MESSAGES: There is a bias towards placing MPAs in areas that are least threatened We found that conservation targets in our study area could not be met solely by avoiding high threat areas A threat selection strategy should be part of the management toolbox Cost-effectiveness in spatial conservation […]

What tools should we use to design marine reserves?

Accounting for the movement of fish and boats KEY MESSAGES: Balancing the needs of conservation with its impacts on fisheries is important when designing marine reserve networks Commonly used design tools based on static models are good at placing reserves to avoid short-term losses to fisheries Static models perform poorly for designing reserves that bring benefits to fisheries […]

Why are fishers not enforcing their user rights?

Sustainable fisheries management in Chile KEY MESSAGES: Assigning user rights to fishers is expected to lead to more sustainable fishing practices by fishers Fishers may choose not to enforce their user rights if they think that government policing of marine areas and punishment of poachers are ineffective In Chile, the government can support fishers’ engagement […]

subtropical and temperate reef species that is protected in Australia.
It is accompanied by Australian Mados (Atypichthys strigatus, the
smaller striped fish) which are subtropical endemics on the Australian
east coast. (Image by Brigitte Sommer)

Conservation of subtropical reefs

Planning for a transition zone in a time of climate change KEY MESSAGES: Subtropical and temperate reefs are currently undergoing ‘tropicalisation’ Going from tropical to temperate reefs, species richness in corals and fishes declines, but that of algae, echinoderms and other invertebrates can increase We should aim to conserve sites that consistently remain important for […]

Protecting marine coastal habitats cost-effectively

Prioritising actions to protect seagrass meadows KEY MESSAGES: Seagrass meadows provide important ecosystem services but are under threat Prioritisations based on cost-effectiveness are more efficient than prioritisations based on habitat maps or threat maps alone Marine coastal habitats, such as seagrass meadows, provide valuable ecosystem services including food provision, carbon sequestration, and coastal protection. But […]

A National Marine Conservation Assessment for PNG

The marine environment of Papua New Guinea (PNG) is vast and diverse. Marine ecosystems directly support the livelihoods of Papua New Guineans through fisheries and development activities, and tourism. They provide an ecological foundation for much of the national economy and prosperity. However, the country’s marine environment is under threat from a growing population dependent […]

certificate in conservation planning from trainers from the University
of Queensland (during one of the Marxan courses run in Malaysia).
From the right are Hugh Possingham, Hedley Grantham and Carissa
Klein. The course was run in 2010 in Sabah.

From Marxan to management

Ocean zoning with stakeholders establishes the Tun Mustapha Marine Park Malaysia has just established the Tun Mustapha Marine Park off the northern tip of Sabah province in Borneo (Malaysia). At 1.6 million hectares, it’s the country’s biggest marine protected area, and Marxan and CEED scientists have played an important role in the planning process that […]

How good is our global network of marine reserves?

Major shortfalls identified in marine conservation KEY MESSAGES: This analysis provides a baseline for measuring how well our marine species are represented in protected areas Currently, most marine species are not well represented within marine protected areas It is imperative that new reserves are located in places that help better represent the full range of […]

Prioritising catchment projects for the GBR

‘Shopping’ for the GBR – it’s a question of benefit, cost AND feasibility KEY MESSAGES: Prioritisation of catchment management projects using cost-effectiveness can increase the outcome several fold A clear quantifiable objective is critical to making wise investment decisions A graphic display of cost-effectiveness helps to evaluate trends and aids in decision making If you […]

Linking regional and national coral reef conservation goals

Multi-objective hotspots and complementary super-spots in the Coral Triangle KEY MESSAGES: Collaboration between Coral Triangle nations makes good sense The challenge is to work out how regional priorities can be incorporated into national decisions Establishing new MPAs in multi-objective hotspots provides good benefits for all six regional objectives simultaneously   Defining management actions for marine […]
