Three complete population surveys were conducted in 2009 and four in 2010 at a number of roost locations, in order to estimate current bat numbers and to monitor the population. Regular bat surveys are also conducted at the Cascade Pigeon roost, which is one of the major roost sites on the island. From these surveys it has been found that the number of individuals now stands at around 9,000. To continue with this level of monitoring, volunteers from the local community have been trained to carry out some of the work, in addition to MWF staff. Similar surveying levels will be maintained in the future.

An Annual Bat Day Festival was organized in April 2009 and June 2010 to sensitize the public about this species and its importance in the ecosystem.
The festival included an exhibition on the bat, newspaper articles, radio talks, activities in schools, and an opportunity for the public to participate in a bat survey. A bat poster and sticker were also created for distribution on this occasion. In 2009, an art competition was launched in primary schools and in 2010 MWF organized a photography competition on the theme Bats in the Wild.
