Ever since we released the media update, we have received lots of interest from people all over the world. It was very useful as it created awareness on the bat and conservation work on the Island. As shown is some of the media coverage received

A South African filming crew that produces programmes for the German National Broadcaster, is interested in filming the bats and some people on the Island. It would be great for the Island. We hope we can manage to do this and we will be sure to post a clip on the blog!

We are also looking into forming a forum for bat monitoring covering the Western Indian Ocean. We would like all bat lovers and people directly involved in bat monitoring within this region to join us. Please email us on pembaflyingfox@gmail.com

We are attending a fruit bat workshop in Mauritius next week. All the bat people in the region and beyond will be attending. We look forward to that and will provide a short update on it!

Thank you for reading!

This is a news release that Fauna & Flora International sent out to various newspapers, sites, blogs and radio stations around the world just in time for Halloween! The story has been carried by National Geographic, Bloomberg, Sky News, BBC Radio World Service, The Cambridge News, Ecoworldly among many others! We are so happy that there is a positive message in the news!

Cambridge, 31 October, 2008 - A once critically endangered bat species, the ‘Pemba flying fox’, has made a dramatic return from the brink of extinction, according to a new piece of research. As recently as 1989, only a scant few individual fruit bats could be observed on the tropical island of Pemba, off Tanzania . Its numbers have since soared to an astounding 22,000 bats in less than 20 years, the new research finds.

This remarkable recovery is testament to the successful emergency intervention efforts of international conservation organisation Fauna & Flora International (FFI), working closely with their local partner, the Department of Commercial Crops, Fruits and Forestry (DCCFF).

The FFI-initiated survey demonstrates that the Pemba flying fox, a type of fruit bat that lives only on Pemba island in the Zanzibar archipelago off Tanzania, is a true conservation success story - sadly something which is all too rare. The species (scientific name Pteropus voeltzkowi) was facing imminent extinction in the 1990’s when FFI first took action to save it. It is one of Africa’s largest bat species, with a wingspan of 5 ½ feet - greater than the height of the average British woman. Once considered a delicacy, these charismatic bats were hunted and eaten widely throughout the island. By the 1990s the bats looked doomed, with 95% of its forest habitat destroyed and an extremely slow reproductive rate (just one young per adult female each year).

This latest survey indicates that the Pemba flying fox population has fully recovered to at least 22,000 but possibly up to 35,600 individuals. In fact, several of the species’ sleeping roosts are now home to over 1000 bats. This amazing resurgence proves that conservation can work, even in the most dire-seeming situations, if the right actions are taken at the right moment.

Over the past 13 years, FFI has helped to reduce the threat from hunting, set up two new forest reserves to safeguard the bat’s habitat and raised awareness of the need for conservation throughout Pemba’s communities. The species has now been downgraded to ‘Vulnerable’ on the International Union for Conservation of Nature’s Red List for threatened species.

Today Pemba flying foxes are much loved by islanders, with nearly 100% of local people expressing support for their conservation in a recent opinion poll. In fact, community-led “Pemba flying fox clubs”, which help protect the bat through education and monitoring, have been popping up all over the island.

FFI East Africa Programme Assistant, Joy Juma, has played a crucial role in FFI’s efforts to save the bat.

“Less than twenty years ago this bat looked set to disappear off the face of the planet forever. Thanks to the enthusiasm of local people, FFI’s ongoing conservation efforts have managed to claw this species back from the brink of extinction,” said Joy. “At one time roast bat was a very common dish on Pemba. Now people value the bats for different reasons.”

FFI is continuing efforts to conserve the Pemba flying fox and is calling for support for the “Pemba flying fox clubs”. The organisation is also broadening its work to develop the island’s ecotourism potential. Several community tour guides have already been trained and a visitor’s centre has been constructed to help local people benefit from the successful recovery of the Pemba flying fox.

Flying Fox Facts:

* The Pemba flying fox is a type of ‘old world fruit bat’, endemic to the island of Pemba, Tanzania, meaning it cannot be found anywhere else in the world.

* The bat’s wingspan is estimated at over 5.5 feet - greater than the height of the average British woman.

* The bat has an average body weight of between 400-650g, which is about half the weight of the average guinea pig.

* Fruit bats are ecologically and economically important - particularly so on oceanic islands - playing a vital role as seed dispersers and pollinators and facilitating ‘gene flow’ between isolated populations of plants.

* Flying foxes belong to the sub-order Megachiroptera, of which there are 167 species worldwide, and are the largest bats in the world.

* Island endemic species are thought to be particularly vulnerable to extinction, primarily due to their small geographic range. The fact that they have evolved in isolation from predators and competitors (particularly humans), makes them vulnerable to the effects of overexploitation and introduced species.

* Islands have been highlighted as one of the priority areas for the global conservation of bats, as they contain a large proportion of the world’s most threatened bats.

The last month has seen me back behind my laptop dealing with excel spreadsheets and data analysis.  It must have been my karma for the wonderful months spent roaming tropical paradise on Pemba Island.  I pinned up some maps of Pemba and pictures of the Flying Foxes on my wall, to help me remember them, as believe it or not – I miss observing them.  They are full of such character and really are fantastically interesting creatures.  Occasionally I see seed pods in the trees in the UK and my eyes are so tuned into bat searching that for a second I might forget where I am! If I miss seeing the bats around, I cannot imagine how much Pemba would do so, if they had become extinct or reduced to such a critical level, as was once imminent.  The bats are such an important part of the Island.  They have played a role in pollination and seed dispersal for many years, which is evident when stumbling across mango trees in the most remote and sparsely inhabited areas – it was not people who planted these trees, but the bats!  They are part of the history and culture of the Island, whether as magical spirits in legends, as a traditional food source or as forest regenerators, they define Pemba and now make the perfect flagship species.

Conservation of this species on Pemba has been a success story.  The last few months of research have revealed an absolute minimum population of 18,000 - 22,000 Pemba Flying Foxes!  This might sound like a lot, but it is important that we don’t give up on these bats as they are still in danger from habitat loss and hunting, amongst other threats.   It is the local communities who live side by side with the Pemba Flying Fox and have been working to protect it.  This is not always straightforward to do so during times of poverty, when food is scarce and with little alternative means of income.  When you look up Pemba Island on the internet you read about a lush green island with fantastic diving, spice tours and secluded pristine bays, but what I think helps make the island so special is this wonderful Endemic Flying Fox.  It would be a shame if anybody visiting the island didn’t drop in to visit the Pemba Flying Fox and in doing so support the communities who are working hard to secure their future (bats and people)!

I noticed a behavioural response amongst the Pemba Flying Foxes that intrigued me.  The bats natural predators on Pemba are likely to be birds of prey, and humans.   I saw the bats exhibit the behaviour twice; once when a bird of prey swooped in close to the colony from above, and once when my field assistant approached the edge of the colony from the ground to take a GPS reading.  A large number of the bats simultaneously opened their wings, and the movement travelled across the colony like a Mexican wave.  Now it could be that they were just preparing to take off if the threat was considered great enough.  But it appeared to me that it may have been a defence mechanism and they were flashing their wings and revealing their russet chests to appear bigger, and startle the predator.  I would be interested to know if anyone else has observed this behaviour in Flying Foxes.
