Coral reefs are some of the most spectacular

they are also some of the most vulnerable.

and the animals and plants who rely on them?

And how can we make sure our protected areas aren't hurting

facing marine conservation biologists today.

Fiji is series of islands in the South Pacific Ocean.

To help balance the need for conservation and making a living,

scientists had suggested that instead of one big  park,

which provides a lot of coverage for one reef system

a better way is to create a system of protected areas

and this way, scientists can protect lots of different habitats

while not excluding people from their traditional fishing grounds.

Now, the only way this string-of-pearls kind of reserve network is going to work

is if each park is connected to other parks.

then because that park is part of a system,

it can be receded from other parks that escaped the event.

scientists ensure that lots of different habitats get protected.

This way, they can make sure all the different marine habitats in Fiji,

This way we don't unduly settle any particular village

or group of people with the economic burden

of having their fishing grounds off limits.

By sharing the cost around the communities,

So if we agree that rather than one big park,

we should have lots of parks of different sizes

then they're probably not going to be self-sustaining.

By looking at how closely related the fish

in each one of these small reserves in Fiji are to each other,

scientists can figure out just how much migration

is going on among the reserves within the system.

Now it is important to look at a variety of different species

But if we look closely and at enough species,

we can see whether or not the necklace is working.

What scientists have found so far is that,

in general, there's a fair amount of connectivity

babies born in the far west are having a hard time

making it to the islands in the far east.

that there are enough parks in both the east and the west

Lessons about reserve connectivity can help across the world

so that their sum is greater than their whole.

And this way, we can keep the beautiful necklace
