The approach to the “village of elephants” in the Sangha Rainforest in the Central African Republic must be made in complete silence. Not even the faintest rustle of backpack on rain jacket should break the soundscape as visitors wade through the sometimes waist-deep swamp at the forest’s edge. The Indigenous Ba’aka guides must be able to listen for any signs of nearby elephants, so they can steer the visitors clear and avoid a close encounter with these giants. When a few pachyderms saunter out of the dense greenery, the Ba’aka shoo them away calmly.
The thick vegetation gives way suddenly to a baï. This is no mere watering hole. The sandy clearing stretches for half a kilometer, more than a quarter of a mile, in the otherwise unbroken canopy of the world’s second-largest tropical forest.
A handful of researchers camp out on a timber observation platform, overlooking a place that has drawn generations of elephants to its mineral- and salt-laden sand and muddy water. They document how the animals use their trunks or tusks to dig into the sand, eavesdrop on the animals’ conversations, and count the many other species that congregate here.
This is Dzanga baï, a meeting place for critically endangered African forest elephants (Loxodonta cyclotis) in the Dzanga-Sangha Complex of Protected Areas where these animals come together in huge numbers to dig for nutrients they can’t get from the otherwise abundant forests.
Baïs are unique to the Congo Basin’s forests, and new research is underway to understand the role these mineral-rich pockets play as a supplement to the elephants’ diet, how this sustains the animals’ population, and how they therefore contribute to the carbon-capture function of the forest.
Unlike the Amazon, the Congo Basin’s forests still have their original megafauna, elephants in particular. And they have these salt-rich clearings. Conservationists are beginning to understand the importance of elephants as forest gardeners here, and how their taste for certain trees and fruits has sculpted a forest that absorbs more carbon per hectare than the Amazon.
The Global Carbon Budget project estimated Africa’s total greenhouse gas emissions for 2021 at 1.45 billion metric tons. Every year, the Congo Basin’s forests soak up 1.1 billion metric tons of atmospheric carbon, storing it in trees and soil; in 2020 carbon credit prices, this service would be worth $55 billion.
Forest elephants, smaller than their better-known savanna cousins or even Asian elephants, prefer certain lower-growing, tasty trees. This picky browsing pressure creates gaps in the canopy that allow other, less palatable but carbon-dense species to reach tremendous heights. Elephants’ appetite for the fruit of these bigger trees then means they spread their seeds far and wide.
A 2019 study from the Ndoki Forest in the Republic of Congo (ROC) and LuiKotale in the Democratic Republic of Congo (DRC) estimated that if elephants were removed from these sites, the loss of their forest-shaping food preferences would reduce the forest’s carbon capture by 7%.
This finding makes a case not only to stop deforestation in the Congo Basin, but to protect the elephants too, as a way to slow climate breakdown, the study authors wrote.

Mouangi baï is only about 250 km (155 mi) from Dzanga baï as the crow flies, but it takes a day or two to travel by road and river to get from one to the other.
Researchers with the conservation organization African Parks and Harvard University’s Department of Organismic and Evolutionary Biology are zeroing in on Mouangi and other baïs in Odzala-Kokoua National Park in the ROC, to clarify the link between baïs, elephants and the forest’s tree species composition.
Nicknamed Capitale by the locals, Mouangi baï in Odzala draws hundreds, maybe even thousands, of elephants, according to Gwili Gibbon, research and monitoring head at African Parks, which manages the park along with the ROC government.
“Mouangi is one of our largest and most renowned baïs,” Gibbon says.
At the intersection of two rivers, Mouangi is more than 1 km (0.6 mi) across and spans 91 hectares (225 acres). It’s the largest of a dozen of Odzala’s baïs that the African Parks and Harvard research collaboration is focusing on.
Odzala-Kokoua National Park extends across 1.35 million hectares (3.34 million acres), and while it has a few thousand baïs, often occurring in clusters within the forest, this ecosystem makes up only about 0.2% of the park’s footprint. Nevertheless, these clearings may be integral to the shape of the forest itself, which is why Harvard assistant professor Andrew Davies and doctoral researcher Evan Hockridge are teaming up with African Parks to understand the importance of the salty watering holes in supporting elephant populations, which then shape the forest mosaic.
The baïs are clearly a hotspot that elephants seek out for their rare minerals in an ecosystem rooted in the nutrient-poor soils typical of the region.
“The elephants use their tusks to scrape topsoil off in specific areas, and eat the finer dust on the surface,” says Hockridge, a landscape ecologist. “They also dig large mining sites or wells, as much as a meter [3 feet] deep.”
The animals’ excavations go even deeper at times, down to where water carries the salt in a more accessible form. The need to ingest the mineral-rich dust, mud and water keeps the animals returning to these sites.

Hockridge says no one has tried to establish if the now-extinct megafauna of the Amazon once made similar clearings there, or if baï size correlates to the size of the animals visiting them.
“One hypothesis is that megafauna effectively create large, nutrient-rich, lick-like clearings. But it hasn’t been quantified that baïs are manufactured or maintained by megafauna,” he says.
The researchers say they hope to answer this puzzle: Do large mammals like elephants maintain and stabilize the baïs?
Anecdotes from the DRC might give the first glimpse of an answer, according to Harvard’s Davies.
“Baïs may be closing in the DRC, and it could be because the elephants are in a war zone, so they don’t have the big bulldozer effect,” he says.
The hypothesis is that if fewer elephants visit and maintain these clearings, the baïs will be swallowed up by the forest.
Gibbon’s African Parks team has set up experimental plots in the Odzala, where they’ve buried salt in the sand at a similar depth to which elephants excavate. Researchers are monitoring these sites to see if more animals will congregate around the plots, whether this impacts the vegetation cover in and around the baïs, and whether there’s a shift in the carbon-capture potential of the surrounding forests.
This study is centered in Odzala, although the researchers say they hope to expand the work into the Ndoki region of the Dzanga-Sangha Complex of Protected Areas.

It isn’t just elephants that congregate at the baïs. These watering holes have a bustling social scene.
Gibbon describes the flocks of African green pigeons (Treron calvus) that gather at Capitale at dawn and dusk; buffalo and several bird species that visit during daylight hours; and the hyenas that can be heard calling after dark as the elephants mine for salt.
Wildlife refuges like these in the Congo Basin are also home to the critically endangered western lowland gorilla (Gorilla gorilla gorilla), two unusual forest and swamp-dwelling antelope — the bongo (Tragelaphus eurycerus) and sitatunga (Tragelaphus spekii) — as well as central chimpanzees (Pan troglodytes troglodytes), bonobos (Pan pansicus), and the endangered gray parrot (Psittacus erithacus).
The forests of Gabon, southern Cameroon and southern Central African Republic also have a high number of baïs, and the findings from these studies could eventually be extrapolated to give an idea of the implications for the Congo Basin more widely.
“The area that baïs’ cover is tiny, but they sustain the elephant population,” Davies says. “If our hypothesis is correct, without the baïs you’d have no elephants; without elephants there’s be no big trees with high carbon density, so carbon storage would go down.”
If the forest loses the baïs, it could lose more than just the elephants or see a change in its carbon-capturing treescape. The baïs would no longer draw the many other animals that thrive in these mineral-dense watering holes, and the tourists and environmental researchers drawn to them too.

Climate change is forcing human and non-human beings to become climate refugees
Climate change. Climate denial. Global warming. Call it what you will, the planet is shouting at us. We have ignored the warning signs for decades, but we can no longer ignore what is happening right now.
Decade old muted warnings have now become loud alarms. We need #ClimateActionNow to prevent human and non-human beings becoming #climatechange refugees. By @RStacilee #Boycott4Wildlife https://palmoildetectives.com/2022/07/31/climate-change-is-forcing-human-and-non-human-beings-to-become-climate-refugees/ via @palmoildetect
Share to BlueSkyShare to TwitterThe definition of refugee or displaced person is someone fleeing a life-threatening crisis. The emerging refugees of this century are fleeing unliveable environmental conditions brought about by climate change and other complex interrelated factors including conflict, disease and famine. Humans and non-human beings alike are becoming climate change refugees. The choices are stark and clear – move and live or stay where you are and perish.
What started out decades ago as muted warnings about the future have now turned into blaring bull horns. Politicians waste time spinning whatever tales fit their agenda but we are out of time if we don’t want to go down with the sinking ship called Earth.
The damage we have done to the planet’s natural resources can never be undone. Equally damaging is the lack of political will to pivot to more sustainable less damaging forms of energy or food production. None of this happened in a bubble nor did it happen overnight.
According to the Internal Displacement Migration Centre (IDMC)’s 2022 GRID report, from the total of 38 million new internal displacements registered in 2021, 23.7 million were triggered by disasters. At the end of 2021, at least 5.9 million people in 84 countries and territories were living in displacement as a result of disasters that happened not only in 2021, but also in previous years (IDMC, 2022).
As far back as the 1970s and 80s we knew much of the damage we were doing. One can only blow up so many mountains or release so many chemicals into the air and water before our fragile ecosystems become damaged beyond repair.
We humans attribute the term refugee (or displaced person) only to other humans. However, the reality is that any living creature who is forced to leave their native home in order to survive is a climate refugee or a climate displaced being.
For non-human beings, the extreme impacts of climate change mean either dying or quickly adapting and moving on. In many cases, adaptation is not a realistic or feasible choice.
For humans living at sea level on the coast – they too will face having to migrate to higher ground and risk losing their homes to coastal erosion and rising tides. These changes are already occurring in different parts of the world.
What the oceans tell us
We’ve all heard the news stories with dire warnings about a warming ocean, rising tides and ocean acidification. This is having a devastating effect on marine animals, as they rely on shells for protection. Acid in the water is thinning the delicate shells of these crustaceans and putting species survival in jeopardy.
Rising tides have already caused erosion for many coastal dwellers. For many small island nations that means many residents will be forced to emigrate or (if possible) move inland. In wealthy nations, waterfront property that was once highly prized will become harder to sell. As buyers will weigh up the likelihood of the property being flooded.
