How Scientists Are Restoring The Great Barrier Reef | Travel + Leisure


people come to the Great Barrier Reef
and expect doomsday it has been publicized that the Great Barrier Reef
is dead I assure you it’s definitely not dead however the Great Barrier Reef is
under threat there are so many animals that are relying on us we need to do
something because if we lose all of this it’s gonna have a huge impact my name is Johnny Gaskell and I’m a
marine biologist on daydream island we got
LuAnn here they’re young LuAnn oops pushy I guess the first thing we do each
day is head into the living room check the animals check corals check the water
quality once we’ve done that we invite guests to come with us on educational
tours to inspire people to want to protect the oceans through the
connections that they make with the animals the Great Barrier Reef is the
largest living structure on the planet to 2,300 kilometer stretch of coral reef
so all of the organisms that make up the Great Barrier Reef colonies of animals
and these little polyps excrete calcium carbonate and make these structures
underneath the soft tissue and that’s how you get your coral structure the
color in the coral is actually an algae that lives inside the coral tissue and
that’s where you get all the bright vibrant colors it is very important to
note that although some parts of the Great Barrier Reef are still thriving on
the other side there’s a lot of parts of the Great Barrier Reef that need help if
something’s not done soon we may lose these places in 2016 and 2017 there was
two mass bleaching events and cuz it was consecutive it had a significant impact
on the Great Barrier Reef an estimated one third of the Great Barrier Reef was
affected by this and we did lose a lot of coral after the 2017 bleaching we
were hit with tropical cyclone Debbie and that cyclone was a category four
that basically sat over the whitsundays through
thirty hours so we did lose a number of sites in the whitsundays – cycling
damage the day I jumped in at Lover’s Gove after the cyclone was about four
weeks after the cyclone I really didn’t want to get in because I kind of
expected what was there it was stills the worst just having that
memory of this underwater city just with corals everywhere fish everywhere it’s
so harsh that one day you got in and you didn’t realize it was your last so now I just want to do whatever I can
to help it get back to as close as what it was possible there’s two methods of
coral propagation that we’re using at the moment collect coral put them onto
nurseries that we’ve actually built under the water in the Marine Park and
then give the corals time in these nurseries to get to a suitable size
where we can then plant them back into the damaged sites the other method that
we’re trialing here at the moment is to use coral raceways that are actually out
of the water these tubs use raw water that cycles through them to basically
replenish whatever’s in there so we actually grab the corals from the wild
put them into the raceways leave them there in the raw water as it cycles in a
controlled environment for four to five months till they get to that size we
need and then I’ll plant them back into the wild into the sites where
and damage the advantage of using the raceways is it’s controlled it’s right
there we have it in front of us and if God forbid another cyclone comes along
at least then we have the coral fragments ready to go inside these
raceways and the outlanding can be done much faster so this is a coral Raceway
this one here I actually designed late one night some crazy idea we’re really
lucky that there Queensland an Australian government actually funded
this project it’s really good to get the support of the government and without
them none of this would have actually happened it’s the first time this is
done in the region so hopefully in the future other places do the same thing so
this is a pretty exciting moment we’ve got the coral raceways up and running
ready to go and the very first coral is about to go in and let’s do it oh the sit all right Carl Wow yeah eight months of planning and this
is it the korells in this will be one of the species that we will be propagating
inside the race ways to then out plant into the wild who have actually named
him an annex Steve the longer we leave him in here and the longer he stays
healthy the more we know that this system really
works first Carol have a look at it it is thriving Kyrgyz doubled in size
already you know what I actually haven’t been in
here since the cycling this spot after the corals have spent a bit of
time in the raceways this is potentially one of the sites that we will aim to
restore so I’m gonna jump in now at the camera see if the girls are gonna have a
happy heart what I just saw down there was clear
cyclone damage it’s there’s not much cover on any of the rock surfaces and a
coral rubble as far as you can see with a little bit of assistance
hopefully this site can come back people all over the world want to come and see
the Great Barrier Reef but there are actually ways that people can come and
help out with the recovery of the reef the citizen science effort is paramount
to this project we want people to come to the region go to the sites that we’ve
recovered take photos send them to us upload them and then hopefully over time
we can get a an indication of how its recovered it’s not too late for the
Great Barrier Reef if everybody does their part then future generations will
get to experience all of this you
