Mgambo Forest Reserve
It is interesting to note that most of the bat species caught were those that live in a mosaic of
habitats, including open woodland and are non-forest dependent. This probably reflects the level
of disturbance throughout the reserve and loss of pristine forest habitat. Those species that live in
forest or on forest edges (ecological type = f) were caught in areas of either dry lowland forest
and/or riverine forest. At trapsite 1, a large number of bats were caught, suggesting a roost close to
the positioning of the mist nets. These were situated in riverine forest on the edge of the reserve
border, close to shambas. Most bats were Rhinolophus species and it is possible that they flew out
of the forest into drier open areas to feed.
