The rediscovery of the short-tailed roundleaf bat, Hipposideros curtus, by Nigerian biologist Iroro Tanshi is a remarkable story of scientific achievement and conservation. This tiny bat, weighing the same as a teaspoon of salt, was thought to be extinct in the 1970s due to deforestation and hunting. Tanshi's discovery in the Afi mountain wildlife sanctuary in Nigeria's Cross River rainforest not only brought attention to the species' plight but also highlighted the importance of local conservation efforts.
Tanshi's work is a testament to the power of scientific exploration and the need to protect biodiversity. Her research, which involved setting up harp traps and mist nets, revealed a small colony of the bat, the only confirmed population still actively roosting. This discovery is significant because it demonstrates the resilience of some species in the face of human-induced environmental changes.
However, Tanshi's work also underscores the challenges of conservation in Nigeria. While the local community shows respect for large animals like gorillas and drill monkeys, bats are still heavily hunted. This is partly due to negative cultural perceptions of bats, which are often associated with witchcraft and bad omens. In some communities, bats are even considered food, with the straw-coloured fruit bat being sold as bushmeat.
In response to these challenges, Tanshi and her colleague Benneth Obitte founded the Small Mammal Conservation Organisation (Smacon) to advocate for bats and other small mammals. They have also launched the Zero Wildfire Campaign to combat the destructive blazes that threaten bats and other wildlife. As part of this campaign, Tanshi and her team designed colour-coded alert systems to guide farmers on safe bush burning and formed a group called Forest Guardians to supervise burning activities and respond to wildfires.
Tanshi's efforts have been recognized with several prestigious awards, including the Goldman Environmental Prize and the National Geographic Explorer Award. Her work not only highlights the importance of protecting endangered species but also emphasizes the need to address the cultural and economic factors that drive habitat destruction and species loss.
In conclusion, Iroro Tanshi's rediscovery of the short-tailed roundleaf bat is a powerful reminder of the importance of scientific exploration and conservation. Her work not only brings attention to the species' plight but also highlights the need to address the cultural and economic factors that threaten biodiversity in Nigeria and beyond.
