Secret ‘sky island’ rainforest saved by new discoveries
Perched on a distant mountain high and surrounded by lowlands, Mabu is what’s often called a “sky island” and is the most important rainforest in southern Africa. BBC setting correspondent Jonah Fisher went to Mabu with a crew of scientists who’ve found dozens of latest species there, serving to to persuade Mozambique to guard it.

“Let me get my magic spoon,” Dr Gimo Daniel says with a smile.
It’s arduous to think about anybody taking extra delight of their work than the 36-year-old Mozambican beetle professional.
We’re crouched round a small gap within the dust not removed from our camp within the centre of Mabu forest. Dr Daniel’s mission, like that of virtually everybody on our expedition, is to search out issues that science has not seen earlier than.
Dung beetles are Dr Daniel’s speciality and he chuckles as he pulls out an enormous plastic tub of bait – his personal faeces.
The scent is as you’d count on. Pungent and not possible to disregard.
Dr Daniel tells me that he has already found what he believes are 15 new species of dung beetles.
“They’ll scent it as much as 50 metres from right here, so they arrive as quick as they’ll,” he says. “It’s brunch.”
Twenty years in the past, Mabu was a secret to all however the locals.
It was ‘found’ for the skin world by Prof Julian Bayliss in 2004. An explorer and ecologist who now lives in north Wales, he was surveying satellite tv for pc pictures of northern Mozambique when he got here throughout a beforehand unknown darkish inexperienced patch.
A primary expedition the next yr confirmed that though locals had been searching within the forest it was in extremely good situation and its measurement at 75 sq. kilometres made Mabu the most important single block of rainforest in southern Africa.
“I used to be like – oh my God – that is phenomenal,” Prof Bayliss remembers.

In early expeditions to Mabu, one in all which I joined in 2009 whereas working as a BBC correspondent in southern Africa, Prof Bayliss was on the forefront of a ‘gold rush’ of discoveries, shortly discovering a number of new species of chameleon, snake and butterfly.
In all Prof Bayliss says they’ve discovered no less than 25 new species, and that is not even counting the dung beetles, a lot of which nonetheless should be formally recognised.
What makes Mabu so particular is its geography. A medium altitude rainforest, it protrudes above Mozambique’s lowlands, makes it successfully a ‘sky island’.
Which means many of the animals and bugs that dwell there haven’t any method of assembly and breeding with different populations, rising the probabilities of them evolving in isolation into one thing distinctive and new to science.
The expedition the BBC joined this yr at Prof Bayliss’ invitation was the primary time a crew of scientists had based mostly themselves proper within the centre of the forest.
Mabu was partially protected by Mozambique’s lengthy historical past of civil conflict, the longest of which resulted in 1992. It was additionally helped by the truth that it’s simply so arduous to get there.
After driving 5 hours alongside dust roads all the tenting gear, meals and gear is loaded on to the backs and heads of greater than sixty porters.
Whereas we, and the scientists, adjusted our strolling boots and dropped hydration salts in our water bottles, the porters, a lot of them sporting simply flipflops, marched up Mount Mabu’s steep slopes.

One of many first to search out one thing new is Erica Tovela, a freshwater fish professional from Mozambique’s Pure Historical past Museum. Within the stream that runs by way of camp she catches a sort of small catfish she’s not seen earlier than.
“I hope that we’ve a brand new species for this space,” she says with a smile as she holds up a see-through bag of lifeless fish. (They are going to be preserved in formaldehyde for additional evaluation and comparability with different related species.) “Wonderful. Will probably be the primary new species for me.”
The method of definitively figuring out a brand new species can take years. It includes writing a peer-reviewed paper in a journal by which the variations between the brand new discovery and its closest family members are outlined and accepted by different scientists.
The following step for Ms Tovela is to get the DNA of her fish analysed and detailed descriptions and pictures circulated. And what could be the title?
“It needs to be one thing mabuensis,” she says. “It’s a pleasant method of claiming we’ve one particular species that’s from Mabu.”

Mabu’s forest is in good situation however that’s to not say that some issues haven’t modified.
The big mammals that after inhabited it like lions, rhinos and buffalos have all been hunted out, most certainly for meals in the course of the conflict. Deforestation has additionally taken a toll, although not as badly as different forests in southern Africa.
“It is very seen that forests (in southern Africa) that I have been to simply 15 to twenty years in the past have now disappeared, reduce down for a lot of completely different causes,” says Prof Ara Monadjem, an professional in small mammals from the College of Eswatini, who was on the journey.
At Mabu the deforestation has to this point been restricted however locals are definitely searching. Digicam traps present hunters carrying animals they’ve caught and we see bodily traps constituted of automobile springs set simply off the tracks by way of the forest.
However on the identical time species of smaller mammals are additionally being found. They included a horseshoe bat known as Rhinolophus mabuensis and a dwarf musk shrew which scientists are nonetheless within the technique of naming and describing.

Not everybody on the expedition is searching for new species. Chicken specialists Claire Spottiswoode and Callan Cohen have a really particular mission. To search out proof that one in all Africa’s rarest birds remains to be alive.
The Namuli apalis solely lives at altitude and there are fears {that a} mixture of the destruction of forest elsewhere and warming temperatures are pushing the small yellow and black hen in direction of extinction.

“Local weather change typically has these results which might be arduous to foretell,” Callan Cohen explains mentioning that typically hotter temperatures encourage snake exercise, which implies extra nests and chicks come beneath assault.
Looking for the uncommon hen includes enjoying it a recording of a Namuli apalis by way of a Bluetooth speaker after which ready to see if any reply.

There’s no signal or sound on the day that we be a part of the search, however a number of days later the hen specialists return to camp late at evening bringing with them excellent news.
They managed to report sound of the Namuli Apalis on one of many greater ridges.
“It is nonetheless a little bit regarding, to be trustworthy,” Dr Cohen says of the large effort it had taken.

So what occurs subsequent? For Mabu, no less than the indicators seem optimistic.
Pejul Calenga, the director common of Mozambique’s conservation areas, tells me in an interview that Mabu is to be became a group protected space.
That can imply no logging or mining is allowed however that the locals who rely upon the forest for his or her livelihoods will handle and be capable to use it.
Of the function performed by the scientists’ work in getting the realm protected, he says: “It is a lot simpler to face up for these areas by which we’ve distinctive sources current.”
Having led so many expeditions into Mabu forest Prof Bayliss is cautiously optimistic that if the administration plan is finished nicely Mabu will flip right into a conservation success story.
He’s already trying elsewhere in Africa for different websites that want safety.
