How can marine preserves best protect sea creatures that move in and out of them? Two ocean scientists describe new thinking about designing marine protected areas.
Nature offers many benefits to people.
Governments around the world have vowed to halt the loss of global biodiversity by 2020, but without more investment, we'll miss some of the targets.

Prime Minister Justin Trudeau has taken swift action on protecting marine areas over the past two years, but he'll need to continue this momentum if he is to cement his legacy.
Scientists call large marine protected areas effective tools for conserving sea life. But do they benefit countries that create them? Scholars explain how Palau's huge marine protected area seeks to protect resources for Palauans.

Palau has banned commercial fishing in most of its waters – while encouraging more foreign visitors.
A century after they vanished, oysters have returned to the Dornoch Firth thanks to an ambitious natural cleaning project
A NOAA vessel explores the the Northeast Canyons and Seamounts Marine National Monument, the first in the Atlantic Ocean.
One of the environmental legacies of the Obama administration is ocean reserves. Two ocean scientists explain why these are a critical but not sufficient piece of conservation.
Whitespotted surgeonfish (
Acanthurus guttatus), found in the Indo-Pacific, crop the upper portion of algae while feeding, preventing macroalgae from becoming established on reefs.
Plant-eating fish control the spread of seaweed and algae on coral reefs. New research explaining why populations of these fish vary from site to site could lead to better reef protection strategies.
Australia’s oceans are home to extraordinary marine life.
Australia has the third largest marine jurisdiction in the world, a vast ocean territory that contains important natural and biological resources. And it needs protecting.

Banning fishing helps fish, but it also helps reef recover from cyclones, disease, and coral bleaching.
Everyone knows the big heads but island's sea life is also spectacular – and unique.
Samal, Philippines: protected area to manage fish recovery.
The combination of local fishing rights with adjacent marine reserves creates incentives to avoid overfishing and could improve nearshore, small-scale fisheries around the world.
Rhinos and blue whales get all the attention, but scallops are worth conserving too.
A fully protected marine reserve off a Scottish island is paying dividends.
Despite the high concentration of sharks in Cocos, some species have declined in number – a signal on the effectiveness of marine preserves.

Divers at the famed Cocos site off Costa Rica record declines in a number of shark species – a sign that marine preserves are limited protection against illegal fishing.
Looks healthy, but still lacks the big predatory fish… how would it rate on the index?
We know that fishing has significant impacts on our oceans and the animals that live in them. Effects can range from habitat modification caused by bottom trawls, stock declines from overfishing or subtler…
Catch my disease.
It has long been news that overfishing persists in many of the world’s oceans. Fish and invertebrate stocks have been over-exploited for our ever-hungry, growing human population, leaving some species…
Kakadu National Park is Australia’s largest – but we need to make sure parks are actually protecting wildlife from threats.
While we can never know for sure, an extraordinary number of animals and plants are threatened with extinction — up to a third of all mammals and over a tenth of all birds. And the problem is getting worse…
