Sydney researchers find three shared conditions across more than 70 studies of conservation success
University of Sydney researchers found three shared conditions across more than 70 studies of conservation success. Every study in the sample describes a success, so for new programmes the pattern is a hypothesis to test.
The Scientist · Science desk
What happened
- Lead author Bing Lin said the successes shared local knowledge valued alongside science, a central role for communities in decisions, and management adapted to local conditions.
- The cases range across coral reefs in Papua New Guinea, chimpanzees in West Africa, grizzly bears in Canada and albatross colonies off Tasmania.
- Villages at the Papua New Guinea reef site periodically close parts of their reefs to fishing, a practice co-author Josh Cinner compared to fallow agriculture.
- In West Africa, some populations of critically endangered western chimpanzees are surviving despite regional decline, often where communities keep cultural traditions and social norms.
Why it matters
- decision Funders designing reef or wildlife programmes can write community roles in management and enforcement into the plan from the start, then measure whether those roles change outcomes.
- constraint The review drew only on sites that beat expectations. Until someone checks sites that met all three conditions and still declined, copying them assumes that a correlation is a cause.
- cost Programmes working with communities that lack the capacity to run such practices under pressure would have to build that capacity first. Building it adds time and money before the pattern can apply.
Every case in the review was included because it did better than expected despite difficult circumstances [4]. The paper appears in Nature Ecology & Evolution, and phys.org describes it as the first to pull such bright spots into one framework [3][14]. Choosing the sample this way limits what the result can mean. To show that the conditions cause recovery, the review would also need sites where they were present and the ecosystem declined anyway. The phys.org account does not describe a comparison group of that kind.
Part of the underlying evidence does have a denominator. Josh Cinner, director of the Thriving Oceans Research Hub and a co-author, has worked with coastal communities in Papua New Guinea for more than 25 years [6]. His 2016 study in Nature ran a quantitative analysis of nearly 1,700 coral reefs, and the Papua New Guinea site came out as one of the global bright spots [7]. "I was blown away," Cinner said of that result [7]. His later research found that the reef closures have lasted because they are part of community life. Ties between elders and younger generations, shared responsibility for the reefs and traditions that reward taking part all hold them in place [9].
The causal step is harder with the chimpanzees. The strongest western chimpanzee populations were found in communities with strong traditions, and also in inaccessible and protected areas [10]. Remoteness, formal protection and community norms all appear together in that record.
Lead author Bing Lin, also of the hub [12], puts the conclusion more strongly. "By bringing together research from around the world, we've shown these aren't simply lucky exceptions," Lin said [13]. We think the spread of cases across species and continents does make site-specific luck the less likely explanation [5].
In our view the framework is most useful as a set of conditions that new programmes build in and then measure against comparable sites without them. One condition is hard to transplant. The review found that the practices worked particularly well where a community had the capacity to carry them out under hard conditions [2]. "The environmental success these communities have achieved comes from extensive local experience and genuine local ownership of decision-making, management and enforcement," Cinner said [11].
What to watch
- A follow-up study that compares bright spots with matched sites that had community management and local knowledge but still declined.
- Results from programmes that build community decision-making in from the start and report outcomes against comparison sites.

"Our study examined different species on different continents that are all facing unique conservation challenges. Yet each succeeded against the odds for remarkably similar reasons: local knowledge was valued alongside science, communities played a central role in decision-making, and management adapted to local social and environmental conditions," Lin said.

Common themes included adaptable practices good for nature and suited to the local environmental and cultural setting, particularly when bolstered by a community with the capacity to implement these practices despite challenging conditions.

Researchers from the University of Sydney's Thriving Oceans Research Hub reviewed more than 70 studies of environmental and sustainability success, where places, species and social-ecological systems perform better than expected despite difficult circumstances.

The success stories include coral reefs in Papua New Guinea, chimpanzees in West Africa, grizzly bears in Canada and albatross colonies off Tasmania.

Josh Cinner, director of the Thriving Oceans Research Hub and co-author of the study, has spent more than 25 years working alongside coastal communities in Papua New Guinea, where one of the world's coral reef bright spots was located.

"I've always known the place was special, but I was blown away when, out of a rigorous quantitative analysis of nearly 1,700 coral reefs around the world, this site came up as one of our global bright spots," Cinner said, citing his bright spots study published in Nature in 2016.

"These villages have maintained a customary practice of periodically closing parts of their reefs to fishing. It's similar to fallow agriculture, giving ecosystems time to recover before harvesting resumes," Cinner said.
- [9]
Cinner's subsequent research found the reef closure practice has endured because it is woven into community life: strong relationships between elders and younger generations, shared responsibility for managing the reefs and cultural traditions that reward participation.

In West Africa, some populations of critically endangered western chimpanzees were surviving despite widespread regional decline; in addition to those in inaccessible and protected areas, the strongest populations were often found where local communities maintained cultural traditions and social norms.

"The environmental success these communities have achieved comes from extensive local experience and genuine local ownership of decision-making, management and enforcement," Cinner said.

"By bringing together research from around the world, we've shown these aren't simply lucky exceptions. They often share common characteristics that can serve as windows into real-world resilience and help guide conservation elsewhere," Lin said.

The review is described as the first to synthesize seemingly unrelated conservation bright spots and bring them together into a single framework.
