Hidden Forest in Mozambique Yields New Species
Space may be the final frontier, but scientists who recently discovered a hidden forest in Mozambique show the uncharted can still be under our noses. BirdLife were part of a team of scientists who used Google Earth to identify a remote patch of pristine forest. An expedition to the site discovered new species of butterfly and snake, along with seven Globally Threatened birds.
The team were browsing Google Earth – freely available software providing global satellite photography – to search for potential wildlife hotspots. A nearby road provided the first glimpses of a wooded mountain topped by bare rock. However, only by using Google Earth could the scientists observe the extent of woodland on the other side of the peak. This was later discovered to be the locally known, but unmapped, Mount Mabu. Scientific collections and literature also failed to shed light on the area.
The site also proved to be important for birds, especially Endangered Thyolo Alethe Alethe choloensis, which is common throughout. “This may be the most important population of Thyolo Alethe known”, remarked Dr Lincoln Fishpool, BirdLife’s Global IBA Co-ordinator, who joined the expedition. “At other sites, forest is rapidly being lost or much of the habitat is sub-optimal”. There were six other Globally Threatened birds among the 126 species identified. Of these, Vulnerable Swynnerton’s Robin Swynnertonia swynnertoni is particularly significant - bridging a large gap between known populations. Mozambique’s only endemic species, Near Threatened Namuli Apalis Apalis lynesi, was also seen. This was the first record of it away from nearby Mount Namuli.
As for Google Earth, Jonathan Timberlake says the digital imagery has helped scientists realise more about the world. It may reveal further unnoticed pockets of diversity, especially in areas like Mozambique or Papua New Guinea. “We cannot say we have discovered all the biodiversity areas in the world”.
The expedition was led by RBG Kew and involved scientists from the Mozambique Agronomic Research Institute and the Mulanje Mountain Conservation Trust in Malawi, as well as BirdLife International. It was funded by the Darwin Initiative.
