Editor’s Note: This is a press release regarding the wildlife photographer of the year selected by Natural History Museum, London. Nature photography, in the correct context, can be an efficient tool for conservation efforts. It not only helps to know about any given piece of land, but also is a powerful tool to raise mass awareness regarding conservation and endangered species. In a world where most humans live their lives, to a large extent, disconnected from the natural world, nature photography can help remind people of the natural world and to inspire a sense of respect for her.
French underwater photographer and marine biologist Laurent Ballesta was awarded for Wildlife Photographer of the Year 2023 for ‘The golden horseshoe’, an otherworldly image of a tri-spine horseshoe crab accompanied by a trio of golden trevallies.
The tri-spine horseshoe crab has survived for more than 100 million years but now faces habitat destruction and overfishing for food and for its blue blood, used in the development of vaccines. But, in the protected waters of Pangatalan Island in the Philippines, there is hope for its survival.
Chair of the jury and editor, Kathy Moran says, ‘To see a horseshoe crab so vibrantly alive in its natural habitat, in such a hauntingly beautiful way, was astonishing. We are looking at an ancient species, highly endangered, and also critical to human health. This photo is luminescent.’
Laurent is only the second photographer in the competition’s fifty-nine-year history to be awarded the Grand Title award twice. He was first awarded Wildlife Photographer of the Year in 2021 for his intriguing image of camouflage groupers exiting a milky cloud of eggs and sperm in Fakarava, French Polynesia.
Young Wildlife Photographer of the Year 2023
Seventeen-year-old Carmel Bechler from Israel was awarded Young Wildlife Photographer of the Year 2023 for his ‘Owls’ road house’, a dynamic frame of barn owls in an abandoned roadside building. Using the family car as hide, Carmel made the most of natural light and long exposure times to capture the light trails of passing traffic.
Carmel was just 11 years old when he began wildlife photography, and this is his first award in the annual competition. ‘I hope to share with my photography that the beauty of the natural world is all around us, even in places where we least expect it to be, we just need to open our eyes and our minds,’ says Carmel.
‘This photograph has so many layers in terms of content and composition. It simultaneously screams “habitat destruction” and “adaptation”, begging the question: If wildlife can adapt to our environment, why can’t we respect theirs?,’ says Kathy Moran.
Catalyst for change
The two Grand Title winners were selected from 19 astounding category winners that showcase the rich diversity of life on Earth. In an intensive process, each entry was judged anonymously by an international panel of experts on its originality, narrative, technical excellence, and ethical practice.
Dr Doug Gurr, Director of the Natural History Museum comments, ‘Whilst inspiring absolute awe and wonder, this year’s winning images present compelling evidence of our impact on nature – both positive and negative. Global promises must shift to action to turn the tide on nature’s decline.’
The newly redesigned exhibition also features videos showing the impact wildlife photography can have, and insights from jury members, photographers and Museum scientists to invite visitors to advocate for the natural world. The journey continues online with planet-positive actions audiences can take. The exhibition will tour across the UK and internationally to venues in Australia, Belgium, Canada, Denmark, France, Germany, New Zealand, Singapore, and more.

Editor’s Note: In today’s piece, we bring to you two issues from New Delhi, India. First, the Dwarka forest is being threatened with deforestation for redevelopment projects. Second, the spotted deer in Deer Park are being relocated to a different state because the authorities now believe that the deer have become “unmanageable.” The eco-suicidal drive of our collective culture is what makes decisions. The needs of nature and life come secondary. Both of these issues are a reflection of the same trend. The two issues are followed by a video from one of our readers. We thank Tannuja for providing us with the stories and David for offering the video.
Deforestation in Dwarka Forest
Location
An obscure 120 acre forestland in Dwarka, New Delhi, India.
History
This dense forest, hardly known to the public of Delhi, is located right behind New Delhi Indira Gandhi International Airport’s T3 Terminal. It is a newly grown forest that is under the threat of eradication due to rapid urbanization taking place in the area.
Importance
Home to several species of both flora and fauna. Wildlife such as spotted deer, nilgai, local species of birds and many other animals have been thriving in the jungle peacefully.
This forest is close to Sahibi river, though it is newly grown forest (around after 2008), it falls in the migratory route of Birds arriving at Great Najafgarh Lake.
It also decreases the habitat concentration (overpopulation stress) from Najafgarh Lake.
Delhi airport emissions are on a constant rise. So, this natural forest soaks up all that massive carbon emissions as it is situated pretty close. Shielding Dwarka citizens from jet fumes.
Delhi airport is an urban heat-island and this forest helps regulate the rising temperature.
Reports state that due to excessive groundwater extraction – nearby areas are going to SINK! This forest falls in low lying area so it recharges so much water to keep the Dwarka & Kapashera areas from sinking.
What is the crisis that has struck?
Recently, it was reported by a local resident named Mr. Naveen Solanki, that the forest is rapidly being destroyed by the Railways Authority for Bijwasan Railway Terminal Redevelopment Project. Since January 2022, he has been defending the forest on his own and has even filed a complaint in the Forest Department of New Delhi against the same. Yet the complaints have been going unheard.
Even earlier, the Rail Land Development Authority (RLDA) had been slapped with a fine of almost 5.9 crore rupees (750,000 USD) by the Forest Department for felling 900 trees in the forest. The aggressive and rapid deforestation in the area continues to take place to this date for the Railways Project.
The wildlife that live in the forest, are at large risk of not only losing their home but being killed off as well by having no other option but to come out on the roads and into nearby areas with human settlements.
“Will the Government of India and authorities involved, do the right thing by putting an end to this atrocious eradicating of our forest lands?”

Relocation of Deer from Deer Park
Location
Hauz Khas, South District, New Delhi, India.
History
This is a 60 year old, sprawling 60 acre bio-diversity park that is situated within the heart of the capital city. It was named after activist and social worker Aditya Nath Jha and popularly known as “Deer Park” because of the significant population of spotted deer — which it has been home to for the last six decades.
Importance
A landmark place in the capital, it is home to not just the spotted deer population but hundreds of local species of birds, most notably the Indian peafowl, ducks and also a significant population of Indian monkeys and rabbits, along with a variety of flora as well.
For the last 60 years, the wild animals in the park have been thriving without any direct human intervention so far. Which is a matter of great feat considering Delhi has lost almost its entire wildlife population throughout the courses of its history.
One of the largest green belts to exist in New Delhi, it would be right to call it as one of “the lungs of Delhi” because it, collectively with other green belts, provides clean and fresh air in the otherwise heavily polluted capital city.
Plus, the existence of wild animals and to see them thriving within the park premises, is a sight to behold.
What is the crisis that has struck?
Very recently, The Ministry of Environment, Forest and Climate Change, India, along with The Central Zoo Authority (CZA) has passed an order deeming the existence of spotted deer population in the park as unmanageable.
So, it not only stripped-off the park of its “mini-zoo” title, but has decided to shut it completely by relocating its entire deer population (over 600 in number) to their “natural habitat” in the western state of Rajasthan — to be served as prey to other wild animals there. The place where the government wants to dump them (Rajasthan) is a desert state, with extreme arid climate throughout the year. These deer are used to living in the bearable, if not pleasant climate of New Delhi throughout their hundreds of generations. Now imagine getting dumped somewhere where there are no water sources readily available along with no grassland. The deer would come into a state of shock from not just the animals who’d want to hunt them but also the scarcity of their regular diets which they have been used to for years. The rise in the number of deer should’ve been a matter of pride and celebration, not an excuse to kick them out of their own home and take it all over.
Also, it would completely be put under the management of Delhi Development Authority (DDA) once the deer are relocated, which means that its landscaping would be altered or changed, to make it more accessible to humans/public.
“If the population of deer has become unmanageable, then why are the entire deer being relocated and not just a percentage of them?”
The concerned people of Delhi also fear that once the deer population is gone, then DDA also might start indulging the catering/event mafias in the park — to host private events and parties of the South Delhi elites in the park premises. The park would become a human-infested picnic spot and the talks about the authorities indulging catering/event mafias in its premises later on just might be right.This would only lead to littering and pollution in the park and impact/disturb its other wildlife residents that have been living peacefully there for the last six decades. Plus, many who have grown up in Delhi, have sentimental memories/values attached to the Deer Park. Hence, losing such a wildlife haven that has been there for the last sixty years in the heart of our city, has become nothing less than an utter shock to all of us.
Editor’s Note: Earlier this year, UN delegates reached an agreement on conservation of marine life on international waters. The agreement, reached after two decades of negotiations, claims it will protect 30 percent of the world’s oceans from biodiversity loss by 2030. It has been hailed as a “breakthrough” by Secretary-General António Guterres. Mainstream environmental organizations have followed suit. These two articles by DGR members question these claims. They explore what the treaty actually says. The article is followed by the invitation to a demonstration against Deep Sea Mining in London on May 3 and 4.
Scrolling through a bright green Facebook page a few weeks ago I saw this headline: “More Than 190 Countries Agree On A Treaty to Protect Marine Life.” Sounds good, but is it really? I wonder if anyone who saw that post actually read and researched the story before reacting to it with likes and hearts and enthusiastic comments.
The article said that The United Nations High Seas Treaty aims to protect 30% of the world’s ocean from biodiversity loss by 2030. My first thought was, why only 30%? My second thought was, There’s got to be something more to this treaty than is being told to us in the article. And there is.
First, let’s look at who is allowed to use ocean resources.
Although the ocean body of water can be used by anyone, the ocean seabed belongs to the coastal state, which is 12 nautical miles from the coast. A nautical mile is a little over a land mile. Each state also has an exclusive economic zone which is 200 nautical miles from its coast. A nation has the right to use the resources in this zone. Beyond the 200 nautical miles is considered international waters — the high seas — which can be used by anyone. The new treaty is supposed to regulate the use of international waters.
Right now, all nations are allowed to lay submarine cables and pipelines along the floor bed of the high seas. That seems destructive enough, but now the UN High Seas Treaty, that is supposed to protect marine life, is going to allow deep sea mining to be exempt from environmental impact assessment (EIA) measures.
Deep sea mining is one of the most destructive activities that can be done to the ocean sea bed. The push for this mining is being driven by an increase in demand for minerals to make so-called renewable energy. More and more of the earth’s land is being mined for these minerals, and the mining industry is now looking to the ocean to continue the destruction.
The land and sea should not be owned by anyone, but as we can see, the most powerful people in this industrial society are just taking what they want. Mining destroys land bases, and now deep sea mining is being added to the destruction of the planet. Whenever governments get together to do something “good,” be very skeptical. It’s usually being done for the good of companies, not the planet.
What they aren’t telling you about the High Seas Treaty
By Julia Barnes
When the High Seas Treaty was announced, conservation groups applauded and social media was abuzz with celebration. The media portrayed it as a long-awaited victory. Commentators claimed that it meant 30% of the ocean would be protected by 2030, that deep sea mining would face strict regulations, and biodiversity would be safeguarded.
The draft text is easily accessible online. It’s a 54-page document, dry and tedious, but clear enough that any lay person should be able to comprehend its meaning.
That is why it is so unforgivable that the treaty has been misrepresented the way it has.
The High Seas Treaty does not guarantee that 30% of the ocean will be protected. It makes no commitment to a percentage, sets no targets. It merely lays out the regulatory framework under which it would be possible to create marine protected areas on the high seas.
When you think of a protected area, you’re likely imagining a place that is off limits to exploitation, where industrial activities are banned.
Under the High Seas Treaty, a protected area is one that is “managed” and “may allow, where appropriate, sustainable use provided it is consistent with the conservation objectives.”
I do not believe that humans possess the wisdom to manage the ocean, nor would we ever be capable of doing a better job than the ocean does itself, with its billions of years of intelligence.
Our track record with managing fisheries should cast serious doubts about our ability to assess sustainability. We must remember that there is no surplus in nature. When something is taken out, even at a rate that is “sustainable,” nutrients are permanently removed from the ecosystem. This cannot happen without consequences.
Even though “protected” might not mean what we expect it to, let’s assume for a moment that an area managed for “sustainable use” is in better shape than one left “unprotected.” Next, we run into the problem of enforcement.
Illegal fishing is rampant, with 40% of fishing boats in the world operating illegally. Marine protected areas are routine victims of poaching. Unless they deploy a navy to patrol the protected areas on the high seas, it is likely these will only be paper parks.
But all this presumes that marine protected areas will, in fact, be created. The process laid out in the treaty makes this quite difficult. With 193 signatory countries, decisions on the creation of marine protected areas are by consensus, and failing that, will require a two-thirds majority vote.
Proposals for new marine protected areas must undergo a review by a scientific and technical body, then consultation with “all relevant stakeholders,” after which the submitting party will be asked to revise the proposal.
Next, there is a 120-day review period. If another party objects to the establishment of a marine protected area within that time frame, the objecting party will be exempted from the marine protected area.
The review period also leaves time for industries to exploit the proposed area before protection is in place. We’ve seen this happen on land when logging companies targeted soon-to-be-protected forests, cutting as many trees as they could before the protection was granted. It’s not hard to imagine something similar taking place on the high seas, with a proposed area being fished intensively during the 120-day period.
What commentators often ignore is that a large portion of the treaty is dedicated to something called “marine genetic resources” and deals with how to share the “benefits” gained from commodifying the genetic material of marine organisms for use in things like pharmaceuticals.
Conservation groups have falsely claimed that the High Seas Treaty puts limits on deep sea mining, when in fact it does not. Deep sea mining is even exempted from environmental impact assessment measures.
The High Seas Treaty may have been a diplomatic feat, but as is often the case when negotiating with so many parties, to achieve agreement, the text ends up watered down and toothless.
This comes as no surprise. What is disheartening is seeing the way news media and NGOs consistently misrepresent the treaty. For a while, the internet exploded with erroneous claims that 30% protection had been achieved, that the ocean had scored a massive victory.
Meanwhile, the deep sea mining industry is gearing up to begin the largest and most destructive project ever imagined on the high seas, and few people have heard of it.
We have an illusion of protection masking a new era of exploitation.
They have been very secretive about the exact location. Which is understandable considering the destructive nature of this profession. But we have found out where it will be held and we need to have an opposition demonstration there. Everyone and anyone in and around London who is against mining the deep sea should come with signs and solidarity. We have set a time and date to show up but feel free to come express your views anytime during the summit. On May 4th at 1pm BST in front of the London Marriott Hotel Canary Wharf 22 Hertsmere Road defend the deep sea!
Species extinction is considered a “likely outcome” of deep sea mining. This new extractive industry threatens not only the fragile seabed, but all levels of the ocean. Mining would produce plumes of sediment wastewater that spread for 100s of kilometers, suffocating the fish who swim throught them.
We have an opportunity to stop this industry before it begins, but we are running out of time. As soon as this July, commercial mining may begin, opening an area of the ocean as wide as North America to exploitation.
We want to show that there is widespread support for a ban on deep sea mining.
We also want to highlight the incredible biodiversity that is threatened, so we are encouraging people to come dressed as their favorite ocean creatures. Don’t let them think your silence means consent.
Editor’s note: The Ambler road is being planned in Alaska to connect the Dalton Highway with the Ambler Mining District. It will cross the Arctic National Park, state lands and native lands. The road in itself poses many threats to the wildlife which is described in the following piece. Many stakeholders are involved in this project, some of them support it and some of them oppose it. Proponents include the Congressional delegates from Alaska and native tribes who hope to benefit from the added jobs in their economy. Those who oppose it are the native groups whose subsistence hunting and gathering is threatened by the road and conservationists.
As George Wuerthner mentions in this piece, for a long time, the mining project was not feasible economically, and thus the area was protected from extraction. As we are extracting the last remaining fossil fuels, mining sites like these, which were too expensive in the past, become more necessary for the so called energy transition. We can expect this trend to grow in the future. As fossil fuels peak, there will be more and more extraction of these last remaining pockets of minerals. This mining prospect in Alaska is just another example of this.
While much conservation and political attention have focused on whether to allow oil development in the Arctic National Wildlife Refuge, another project, the Ambler Mining Project, and road construction proposal may pose even greater threats to the Arctic’s wildlife and wildlands. Despite this threat, The Ambler project has thus far received far less attention from the media, politicians and conservation organizations.
The proposed 211-mile Ambler Road would connect the Dalton Highway (pipeline haul road) with the Ambler Mining District in the western Brooks Range. The ore belt that stretches for 200 miles contains copper, cobalt, lead, and zinc and could be one of the most valuable deposits in the world, especially as people turn to electric vehicles.
There is new interest in encouraging the US development of critical minerals and energy, and the Ambler Mining proposal benefits from this push for US sources of minerals.
Although these deposits have been well-known for decades, the cost of mining, smelting, and transportation has precluded development. (I knew about the ore deposits in the 1970s when I lived and worked along the Kobuk River).
Years ago, I taught a class on Alaskan Environmental Politics. I emphasized that Alaska has more oil, coal, minerals, and even forests than most other parts of the United States. Many of these resources remain undeveloped because of the harsh climate, remote locations, and lack of access.
There are, for instance, substantial forest resources in Southeast Alaska. Still, they cannot be cut and transported without government subsidies because it’s cheaper to log trees in Oregon or Washington.
The Prudhoe Bay oil fields were the world’s 10th most significant oil reserves, and the other nine were in the Middle East. The Prudhoe Bay oil fields would have remained undeveloped had it not been for the construction of the Alaskan Oil Pipeline, which made these oil reserves economic to develop.
The Ambler Mineral deposits are considered “world-class.” Getting a road to the Ambler Deposits is the first step in making mining operations profitable. The Bureau of Land Managment (BLM) and the Corps of Engineers under the Trump Administration approved the road plan in 2020, and officials agreed to issue a 50-year right-of-way for the Alaska Industrial Development and Export Authority, the state public corporation working to develop the project.
However, the Biden Administration halted the road project while a Supplemental EIS process mandated by the courts was completed. However, my sources in Alaska suggest this may be for show. The comment period ended on November 4th, and the BLM review will likely be published sometime in the new year.
If you want to understand politics, all you have to do is follow the money.
The mining claims are owned mainly by local Iñupiat people living in NW Alaska coast and inland along the Kobuk River, represented by NANA corporation. They also operate the Red Dog Zinc mine, one of Alaska’s most significant mining and polluted sites.
During the land selection process created by the Alaska Native Claims Settlement Act (ANCSA), native people targeted the lands with valuable known mineralization or fossil fuel resources.
In the case of the Ambler mines, NANA shareholders are likely to be employed during road construction and mining operations.
One study estimates that 20% of all construction jobs will be held by local villagers, providing significant money input into these rural villages. NANA corporate leaders likely believe they are working in the best interests of their constituency.
In addition to NANA and some residents who would benefit from jobs and royalty payments, the road is also supported by the state of Alaska. The Alaska Industrial Development and Export Authority (AIDEA) would own Ambler Road.
Alaska’s Congressional Delegation, including newly elected half-Native Democrat Mary Peltrola and Republican Senator Lisa Murkowski, support the road and mining proposal. Peltrola has also joined her Republican counterparts in the Senate to support oil development in the Naval Petroleum Reserve.
The road, if built, would likely lead to road sprawl and the expansion of development in the region, including perhaps oil development in the Naval Petroleum Reserve to the north of the Brooks Range.
Although the supporters point out that the road would be a private road only accessible to industrial use, opponents point out that the same claim was made about the Pipeline Haul Road. However, in 1994 the state opened the Pipeline Road (Dalton Highway) for unrestricted, public use.
Opposition to the road comes from Tanana Chiefs and other Athabascan Indians living along the Koyukuk River and tributaries. The Athabascan would gain no advantage to a road except perhaps for more accessible and cheaper shipment of supplies. But they fear the road would disrupt subsistence hunting and gathering.
The Athabascans are not necessarily opposed to mining or oil development themselves. Doyon Native Corporation, which represents the Athabascan people of the Yukon Basin, during the land selection process of the Alaskan Native Claims Settlement Act has specifically targeted mineralized lands. Today, they have several active mining operations. However, Doyon has neither endorsed or opposed the Ambler Road and mining projects.
However, Doyon has proposed alternative road access to the Ambler district from Nome.
So, in essence, the road is pitting one ethnic native group against another.
In addition to opposition from some native people, many conservationists also oppose the road. The Ambler Road, if built, would cross the Gates of the Arctic National Park and Preserve and numerous other protected areas like the Kobuk Wild and Scenic Rivers.
The National Park Service did an excellent review of the potential impacts of the road on wetlands, water quality, fish, wildlife, subsistence, and recreational impacts on the park that applies to the total road mileage.
Conservationists and native people opposed to the mine have produced a good video about how the road would impact the Arctic:
An environmental review by the BLM in 2020 found that the road would impact salmon, caribou, and other wildlife.
Roads can be semi-permeable barriers, and although crossing such obstacles is possible, caribou may shift or entirely abandon their seasonal habitat. The disturbance and activity along the road and mining operations are likely to affect caribou in other ways. Studies have shown that caribou may travel up to 9.3 miles to avoid roads and 11.2 miles to avoid settlements.
Thousands of caribou like this one traditionally cross the Kobuk River near Onion Portage in the fall. Accessibility statement: Single caribou looks directly at the camera surrounded by red shrubs, with river and forest in background.
For instance, a study of the Native-owned Red Dog Mine Industrial Access road north of Kotzebue found that just four vehicles an hour affected the migration of 30% of collared caribou, or approximately 72,000 individuals of the 2017 population estimates.
Linear features like roads also are used by predators like wolves. This can increase predator influence on prey like caribou. Roads and seismic lines in Alberta have led to increased predation on woodland caribou.
It also does not take much imagination to see that this road will eventually be extended to the coast by Kotzebue, fragmenting the entire western Brooks Range’s ecosystems.
Nevertheless, the road’s construction was approved by the Trump administration. However, the Biden Administration has ordered the Bureau of Land Management to reevaluate the Environmental Review.
The BLM accepted comments until November 4th. Whether the BLM review changes the decision to move forward with the road remains to be seen.
But my sources in Alaska say that the Biden Administration is likely to approve the road to help Alaskan politicians, perhaps with stricter regulations designed to address environmental concerns. The Biden Administration doesn’t want to oppose new Democratic Congressional Representative Mary Petrola who is a supporter of the mine road. Murkowsi was critical to Democrats in voting to convict Donald Trump for his role in the Jan. 6th insurrection, was one of three GOP to vote for nomination of Judge Ketanji Brown Jackson and she was the only GOP member to support the Voting Rights Bill. Biden does not want to alienate her potential support for other Democratic agenda votes.
I can’t emphasize enough that this road is one of the biggest threats to the Arctic’s wildlands and wildlife. It is bigger than just the development impacts that may result from the Ambler Mining operations. I have no doubts that the road, if built, will eventually make other mineral and oil, and gas sources economically viable to develop.

Editor’s note: The oceans have absorbed more than 90% of the excess heat trapped on planet earth due to global warming. Greenhouse gases are also absorbed into the ocean which has increased the acidity of ocean water significantly. Increased heat and acidity makes reproduction and survival more difficult for calcifying organisms such as corals and other marine life. It should be no surprise to anyone that we see coral reefs dying globally. So are plankton populations, fish populations, and countless other species. What is surprising is that efforts to halt and reverse greenhouse gas emissions have thus far been so tepid and ineffective. We must change that.
Article summary:
In 2003, a marine heat wave devastated coral reef communities in the Mediterranean Sea, including the reefs in the Scandola Marine Reserve, a protected region off the coast of Corsica.
More than 15 years later, the coral reef communities in Scandola still have not recovered.
Researchers determined that persistent marine heat waves, which are now happening every year in the Mediterranean, are preventing Scandola’s slow-growing coral reefs from recuperating.
Human-induced climate change is the culprit; persistent rising temperatures in the ocean have normalized marine heat waves, not only in the Mediterranean, but in the global oceans.
For years, Joaquim Garrabou donned scuba gear and dove into the waters of the Scandola Marine Reserve in Corsica to find a paradise. Twenty meters (66 feet) beneath the surface, there were reef walls draped with soft red coral (Corallium rubrum) and red gorgonian sea-whips (Paramuricea clavata), all swarming with fish and other sea creatures. But in 2003, a marine heat wave hit Scandola, leading to the death of many coral reefs. More than 15 years later, the reefs have still not recovered.
Now when Garrabou dives at Scandola, he’s greeted by the skeletons of once-thriving corals.
“It’s like seeing someone who is ill, who has a disease that you cannot find the solution for,” Garrabou told Mongabay in a video interview. “You hope that someday there will be a [solution] but you see that there’s not much hope.”
After the 2003 marine heat wave, Garrabou and colleagues began monitoring Scandola’s coral reefs to track their recovery. But after accumulating reef survey data and temperature data over many years, they eventually realized they were actually tracking the reefs’ collapse. The results of their long-term study were recently published in Proceedings of the Royal Society B.
“We knew something bad was happening to the corals around the world, but we weren’t expecting a collapse in all of the populations that we studied,” study lead author Daniel Gómez-Gras, a marine ecologist at the Institut de Ciències del Mar in Barcelona, told Mongabay in a video interview. “The point of tracking these populations for such a long time was to show recovery in the long term because we expected that the populations — maybe not in five years, but in 15, 20 years — [would be] able to recover. However, we saw a collapse.”

‘We don’t call it bleaching’
The data showed that marine heat waves were happening every year in different parts of the Mediterranean between 2003 and 2018. For 12 of those years, the water temperature at a depth of 20 m reached more than 23° Celsius (73.4° Fahrenheit), which is considered a sublethal threshold for corals. And for four of those years — 2009, 2016, 2017 and 2018 — temperatures at that depth breached the lethal threshold for corals at 25°C (77°F).
The researchers found that the ceaseless heat wasn’t allowing these slow-growing coral reefs to recover.
“Frankly, I never thought that I would be seeing it,” Garrabou said. “And it’s happening really fast.”
Soft coral species in the Mediterranean don’t “bleach” the way that tropical corals do, Gómez-Gras said. That’s because Mediterranean corals don’t have a symbiotic relationship with zooxanthellae, the algae that tropical corals expel when they experience heat stress.
“We don’t call it bleaching here in the Mediterranean for these coral species, since they don’t bleach,” he said. “They directly die with a loss of tissue and skeletons being exposed.”
While the results of the study are relevant to many coral communities across the Mediterranean, the researchers chose to focus their study on Scandola because the area had been established as a marine protected area (MPA) in 1975, and had been relatively free from other human pressures such as fishing and pollution. This helped them eliminate other possibilities for the coral reef population collapses and to pinpoint marine heat waves as the reason for their demise.
Researchers used to think that deeper reef communities might shelter coral species from heat stress. But it’s becoming increasingly clear that this isn’t the case, not only in the Mediterranean, but in other parts of the world, including coral reef sites in the Pacific.
“We are witnessing that if you go deeper, [there is still] impact,” Garrabou said.

Raised temperatures
Human-induced climate change is responsible for the heating of the oceans — and it’s becoming hotter and hotter in the water. According to another study, the global oceans have broken a heat record for the sixth year in a row. As the oceans warm, heat penetrates downward — and this heating trend will continue even if emissions stop tomorrow, Kevin Trenberth, co-author of this separate study, told Mongabay in January.
A related study also found that marine heat waves have become the new normal for the global oceans as climate change rapidly transforms our world.
The Mediterranean may be feeling the impacts of climate change even more intensely than other parts of the world. A report published last year by WWF found that the Mediterranean was warming 20% faster than the rest of the world’s oceans.
Gómez-Gras said the accelerated warming in the Mediterranean has partly to do with its semi-enclosed shape. While this is unique to the region, he added that the Mediterranean shows what will happen in other parts of the ocean due to climate change.
“Marine heat waves are becoming the new normal in the Mediterranean Sea,” Gómez-Gras said. “So you can guess that in the future, it can become the new normal [elsewhere] in the world.”
Georgios Tsounis, a marine biologist at California State University, whose work was based in the Mediterranean for 11 years, but who was not involved in this research, praised the new study in Proceedings of the Royal Society B for its “valuable approach.”
“We need more long-term demographic studies such as this one to better understand where our environment is heading in the future,” Tsounis told Mongabay in an email.
While the study is focused on the soft coral communities of the Mediterranean, Tsounis said the research can help us understand how other coral communities “may or may not recover from repeated stress over a period of 15 years.”
“We are seeing coral mortality in other parts of the world as well,” he said. “The tropical coral reefs make sad headlines every year. But in the tropics we are mainly concerned with reef-building hard corals (as opposed to the soft corals in this Mediterranean study). The temperature range and entire cause-effect mechanism differ between these two examples. What is common to most of these scenarios is that the corals have adapted to a narrow set of environmental conditions, such as temperature, over a long period of time, and are sensitive to changing climate.”

Seeking refuge
The researchers said they are searching the Mediterranean for “refugia,” places that offer coral reefs protection from thermal stress. One possible place could be the waters off the coast of the Calanques near Marseille, France, which seems to get enough cold water to protect its corals, Garrabou said. That said, the coral reef communities here experienced mass die-offs during marine heat waves in both 1999 and 2003. But since then, the region hasn’t had any major warming, and the corals have been able to slowly recover, he said.
While there are currently many places of refugia for coral communities across the world, a new study found that most of these places will disappear once the world reaches 1.5°C (2.7°F) of warming above pre-industrial levels, which is likely to happen within the next decade.
But it’s not just climate change placing pressure on the Mediterranean — fishing and pollution are additional stressors to the region. Because of this, Garrabou said it’s important to establish MPAs with strict protective measures to enhance the resilience of coral reef communities.
Currently, there are more than 1,200 MPAs in the Mediterranean, but only about 0.02% of the area they cover is closed to fishing year-round.
While the future looks grim for coral reefs, Garrabou said he feels hopeful about the momentum that’s building for the establishment of MPAs, especially with global efforts to protect 30% of the world’s oceans by 2030.
“When we provide the right conditions and the right tools, nature can be really generous and nature has demonstrated that it can bounce back,” he said.
But he said that MPAs need to be urgently established for the oceans to reap their benefits. “It has to happen,” he said, “and it has to happen fast.”
