Salim Ali’s fruit bat Latidens salimalii, is endemic to southern India This bat
has long been considered as one of three rarest bats of the world. This is because, until
2000, there were only few individuals caught in mist-nets and the total population is
considered to be less than few hundreds (~ 250) with tiny distribution range. Based on
the above information IUCN has classified this species as “Critically Endangered”. But
recent studies show that the species’ population is between 800-850 individuals (the
estimate is based on the counts in day roosts). Also the distribution and the extent of
occurrence of this bat are getting wider than before as new roosts were being located
particularly in two regions of Western Ghats; 1) High-Wavy Mountains 2) Agasthiyar
Hill Range in Southern India. The day roosts are typically located in high-altitudes, and
are usually closer to the proximity of water source. They rely on wild fruits belong to
the plant spceis like Ficus, Elaeocarpus, Diospyrus, Prunus, Syzygium and Palaquium
in both regions. Currently the bat species face fewer threats; a) anthropogenic activities
to some roosts might disturb their colony, b) roosts located in private estates may face
habitat alterations. Thus, habitat modeling studies (using advanced tools like GIS)
would better depict the long term threats to this species. But the IUCN has to re-review
the current status (i.e., Critically Endangered) of L. salimalii.
