Collaboration across the sea

Gazing across the Mediterreanean Sea, home to hundreds of
species of threatened species and regarded as a biodiversity hotspot.
Protecting this natural value is beyond the scope of any single nation
lining its shores. How do you approach the task of collaboration in a
such a complex sociopolitical environment?

Collaboration across the sea

Better marine conservation outcomes from a little cross-boundary collaboration Key messages: Decisions around marine conservation can be substantially influenced by whether they cross international and political boundaries. Taking this into account, it is important to understand the challenges, opportunities and constraints involved in conservation collaborations. Collaboration can occur at a variety of spatial scales (regions, […]

The ocean realm is fundamentally a three dimensional space.
Conservation planning in such conditions is more efficient when features
and threats can be stratified with depth. (Photo by Thomas Vignaud)

Taking spatial conservation to the next dimension

Adventures in 3D Key messages: Conservation features often vary with depth in the ocean realm 3D systematic spatial conservation planning has the potential to deal with this variation We demonstrated that a 3D approach to conservation planning in the Mediterranean Sea has the potential to generate more efficient outcomes than the traditional 2D approach Spatial […]

Whale story

Modelling the future of Earth’s titans During the 1900s, many whales were commercially harvested almost to extinction. Amongst the most impacted were the larger baleen whales, those species with comb-like baleen plates used to strain the water for food (such as krill and small fish). In 1983 the International Whaling Commission decreed a moratorium on […]

Viv Tulloch presents at the IWC

Viv Tulloch recently completed her PhD with CEED working on several different threat-management problems in collaboration with the Wildlife Conservation Society, The Nature Conservancy, CSIRO, and the International Whaling Commission (IWC). At the most recent IWC Scientific Meeting in Slovenia, she presented findings from the multi-species model developed during her PhD. The model explores interactions […]

Students and teachers in the Marxan training course run at Brazil’s
Mato Grosso do Sul Federal University in 2015. Morena Mills, Jennifer
McGowan and Gustavo Almada each have their intitials over their heads.
Special mention also should be made of Prof Reinaldo Lourival (RL). He’s
an experienced Marxan user and helped realise the Marxan workshop.

Marxan plumbs new depths

Planning deep-sea protected areas around Brazilian oil fields Key messages: Marxan was used to explore options for deep-sea MPAs that are politically feasible and environmentally rigorous The process developed has application for other regions seeking to protect deep-sea biodiversity on and around deep-sea oil fields, mining prospects or fishing areas Since its inception, CEED has […]

Don’t let ‘climate’ crush coral efforts

Following a recent international coral science conference, CEED researcher Jennifer McGowan led a short correspondence to Nature asking to researchers and managers not to lose sight of where they can make the most difference. “The message of the correspondence aims to unite the coral reef science and management communities after the International Coral Reef Symposium […]

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 […]

Malaysian fisheries: which design tools get the balance right?

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 […]

The blue groper (Achoerodus viridis, the large blue fish upper left) is a
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 […]

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 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 […]

Tracking seabirds for conservation

Seabirds are arguably the most threatened group of birds on the planet and conservation scientists all around the planet are working to understand how we can better protect this group of animals. Many studies involve tracking the movements of these highly mobile birds using a suite of tracking technology (telemetry). CEED recently joined forces with […]

Restoring marine coastal ecosystems

Counting the costs and assessing the feasibility KEY MESSAGES We examined the cost and feasibility of restoration in marine coastal ecosystems The median price was around US$80,000 per hectare, the average price was up at US$1,600,000 per hectare Feasibility ranged from 38% for seagrass, to 65% for coral reefs and saltmarshes Coasts are popular areas […]

Major shortfalls in marine conservation

A new study says that more than 17,000 marine species worldwide remain largely unprotected. The authors (including several CEED researchers) looked at the ranges of some 17,348 species of marine life, including whales, sharks rays and fish, and found that 97.4% have less than 10% of their range represented in marine protected areas. major-shortfalls-identified-in-marine-conservation.html

More to marine biodiversity than GBR

Two CEED researchers have made a plea for a review of the Commonwealth marine protected areas around Australia to be more representative. Jennifer McGowan and Hugh Possingham have recently posted an editorial on the National Geographic blogsite pointing out Australia has a big opportunity to better conserve our marine natural heritage. The researchers bemoan the […]
