Nice to read a paper that's looking for paths of persistence instead of only documenting decline. Climate stories often end with "thing are getting worse", this one also asks where ecosystems might still persist if local conditions are managed well.
The biodiversity in West Africa in general is completely underrated. I mean, Darwin solidified his trajectory in life a few short days after the Beagle anchored off of Cape Verde (a place he initially detested then fell in love with).
I'm hoping that Cape Verde's World Cup success story translates to more eye balls on stories like this (with the mere mention of the country landing it in search results). Which means more attention, money and research to West Africa's relatively fragile but diverse ecosystem.

There’s more but there’s a few off the top.
In general the US is primarily focused on erosion control since the beaches are disappearing. Coral is more an afterthought especially with the gutting of all our science. Australia is really leading the way here with AIMS and Saudi has KAUST. Big ups to the Paul Allen Foundation though, they gave Scripps $10M a few years back.
Fun stat to end with: coral reefs are responsible for over $10T in annual economic value. They get less than $1B a year to ensure they stick around. We’re gonna change that.
The irony surely being that the "economic value" here supposedly worth $10T is, ultimately, the very cause of their undoing (human economic activity is somewhat directly correlated with environmental destruction). Personally I'd prefer to live in a world where we saved coral reefs for their own sake and not for their economic value.
Still, it's a detail. Well done for the amazing work you're doing. We all depend on people like you and the organizations you mention.
I’ve always been curious as to the level of success these programs achieve compared to just letting nature respond on its own. There are many cases where “dead” areas come back to life with abundance and give me pause as to whether we should for the most part just get out of natures way.
They can only survive short duration events. At some point the temp and time is too much and they die. The only way they come back is reintroduction.
We’ve lost over 50% of the reefs and are expected to lose 90% by 2050.
There are many amazing solutions. Some use corals more resistant to heat stress. Australia has seen some promising results with seed boxes. I know of a few other amazing solutions currently in the lab.
We have already gotten in natures way. So now we need to help nature with our technology.
"So now we need to help nature with our technology."
I guess the best help, would be stop getting into natures way so brutally, but since transforming the whole industry takes time and making people aware and care is even harder, some technical solutions to offset some damage is of course welcome.
I recall reading that the corals can reproduce both sexually and by cloning, with most in nature using cloning. The researchers brought them back to a lab and bred a bunch of them and found a lot of offspring could thrive in the warmer more acidic water, so they wanted to reintroduce them to a reef (or maybe they had). Been a while but it was interesting. Not sure what it takes to shift away from cloning in nature, but waiting for most the reef to die off seems backwards ;-)
I would suppose getting out of nature's way happens in one of two ways - infrequently because there is nothing of value in an area left to extract so people leave it alone, or infrequently because there is regulation forcing people to leave it alone.
Homeostasis, that was probably an option for most of nature in the 1950s or something, I think the damage is too great to just leave the reefs, forrests and other habitats to "fend for themselves". Even if what you say is true from an environmental perspective, we also have to fight to protect these areas from exploitation from fisherman, mining etc.

And for those commenting about risk from tourism, this is mesophotic coral at 175 feet. It’s out of range of recreational scuba much less shallow-reef snorkelers. Only technical divers can reach this reef. That’s why it hadn’t even been explored for all this time.
vaguely related I read a fascinating story the other day about basically garbage dumping of leftover oyster/clam shells being used to re-seed a marine ecosystem off the Florida Keys
And to be clear, in GP's link, living oysters do show up, but they weren't put there deliberately (the shells and every other development provided the larvae with places to grow and establish themselves). The NY project started with oyster larvae placed on discarded shells to deliberately create the new environment with an oyster population.
did this start as just shells? Because I remember reading something a long time ago about this and they were just putting shells in the bay in metal cages.
Amazing that they're actually progressing on a billion oysters. That's incredible. I wonder when it becomes self sustaining, and just reaches a billion on it's own.
> As part of the strategy, discarded oyster shells from over 70 New York restaurants are collected and left outside for a year to be naturally cleansed of organic matter. Baby oysters are then placed on the shells by students at New York Harbor School, a maritime-focused public high school located on Governors Island. [10]
Could you please stop posting unsubstantive comments and flamebait? You've unfortunately been doing it repeatedly. It's not what this site is for, and destroys what it is for.
The comment is flippant but IMO it's also a pithy summary of an important argument in this debate. To which some of the responses are thoughtful and substantive.
Tangential: I quite often slap down comments for much the same reasons you're using. No objections there, in fact I wish more people would do it.
Very few people travel to visit the Amazon especially in Peru, Bolivia, and Ecuador. In the absence of tourist money these amazing ecosystems are being turned into agriculture and logged. In the protected areas supported by eco tourism the sound of the insects is deafening. But a few miles away in the banana plantations the area is completely silent. Even on “organic” banana plantations every insect is killed.
I walk an old logging trail near my house. 5 years or so ago I was walking and came across a lady slipper. Then another and another. I stopped counting at around 100. I've never seen so many in one place. It was incredible. I stopped taking people there when they've bloomed to help preserve them. It's a free and public place, but on a lightly travelled road so it doesn't actually get much traffic. Anyone that takes that walk at the right time of year will see them, but I've no interest in helping the inevitable happen if word gets out.
You don't even need to actively censor it; it's human nature to not only solely pay attention to bad news, but also to amplify it. It's generally true for all mammals, but they scale of things we're conscious of is orders of magnitude larger than any other mammal species.
Not in developing countries. Especially not when in the commons (e.g. territorial waters). Awareness + western tourism is often the only way these things get protected.

You'd prefer to live in a world where labor is free and we don't need to work for anything? I like the current world better.
No, we'd prefer a world in which we don't destroy the environment for the sole purpose of creating more unneeded and largely useless widgets.

One major issue though is diversity. Many coral gardeners use fragments to clone one type over and over.
Also pests aquariums have some of the toughest pests imaginable

Homeostasis is unnatural.
Yep you’ll see most stats base off ~1950. This is when we started noticing and especially in the ensuing decades as SCUBA equipment got good.
YAY!

they were doing that in New York as well if I'm not mistaken

Not having heard of this plant before, I was rather confused why people would leave so much footwear on this trail.
Apologies, I assumed common knowledge when I shouldn't have. It's a lovely orchid that resembles a slipper.

Yeah, only publish stories about coral bleaching, animals going extinct, and forest fires. Censor any good news at all costs!
You don't even need to actively censor it; it's human nature to not only solely pay attention to bad news, but also to amplify it. It's generally true for all mammals, but they scale of things we're conscious of is orders of magnitude larger than any other mammal species.
Forest fires are natural.
Coral bleaching seems too actually be a sign of prosperity, not suffering.
Glyphosate has made forest fires worse.
Bleaching happens when the symbiosis breaks down due to elevated temps. That is due to suffering and causes suffering.
>Glyphosate has made forest fires worse.
How? How does this work?
>Bleaching happens when the symbiosis breaks down due to elevated temps.
The first part is correct, the second is unknown. In 2016, 84% of corals bleached, the highest number. Did global warming peak in 2016?
I admit, saying "prosperity" was provocative. It's probably not a sign of prosperity. But what exactly it is a sign of, we have little idea.
I'm not a big fan of synthetic chemicals in the food supply but I can't help wondering how Glyphosate has made forest fires worse?
I think it depends. In developing countries, ecotourism even when poorly managed is better for conservation than uncontrolled fishing/farming.
Not in developing countries. Especially not when in the commons (e.g. territorial waters). Awareness + western tourism is often the only way these things get protected.
Hey there Mr. Jambo
What's the point in it existing then? Just for a couple of the chosen few?
I'm aware that lots of people can be destructive, but there's a balance.
For its own sake, not ours.
Beauty does not exist for its own sake, it only exists in the mind of someone else.
Shut up about the exact location, but do tell us about it. Just make it hard enough so the ignorant tourism industry cannot find it.
That's wild
Chemical sunscreen famously kills coral.
Some dermatologists have noted that sunscreen is little used in Africa. [1]
I’m not saying that is the only explanation for the reef’s preservation, but it’s likely a significant contributing factor.
[1] https://theconversation.com/sunscreen-wouldnt-have-saved-bob...
The evidence for sunscreen killing coral is pretty thin and the evidence that so-called mineral sunscreen _not_ killing coral is non-existent.
That and being 175 feet below the surface. You’re not getting “sunscreen” on mesophotic coral.
