Percival's Trident Bat

Assessment Information [top]

Red List Category & Criteria:

Least Concern ver 3.1

Year Published:

2008

Assessor/s:

Mickleburgh, S., Hutson, A.M., Bergmans, W., Taylor, P.J., Aulagnier, S. & Fahr, J.

Reviewer/s:

Hutson, A.M., Racey, P.A. (Chiroptera Red List Authority) & Cox, N. (Global Mammal Assessment Team)

Contributor/s:

Justification:
Although poorly known and with some recorded population declines, it is listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

History:

2004

Vulnerable

Geographic Range [top]

Range Description:	Percival's trident bat is largely confined to southern Africa, with records from South Africa (KwaZulu-Natal), Swaziland, south-east Botswana, southern Zambia, Zimbabwe (the core of the distribution), and extralimital records from southern Democratic Republic of Congo, Malawi, northwestern Mozambique, and coastal Kenya (Taylor 2000). It has also been found on Mafia Island in Tanzania (unpublished record). It elevational range is from sea level to 1,000 m.

Population [top]

Population:	Large fluctuations in population numbers are known, and it is prone to local extinctions. It is never found in very large colonies, with the largest known colony (of about 300 individuals) being reported in KwaZulu-Natal, South Africa, on the southern section of its range. However, the current estimated population size of the KwaZulu-Natal colony is currently only 50 animals. There are no population estimates from elsewhere in its range, although the largest population might be in Zimbabwe.
Population Trend:	Unknown

Population Trend:

Unknown

Habitat and Ecology [top]

Habitat and Ecology:	It presumably occurs in savanna areas where there is sufficient cover in the form of caves and mine tunnels for day roosting (Taylor 2000). It feeds exclusively on moths, and appears to be very sensitive to disturbance.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	There have been seemingly stochastic extinctions of colonies, though it is not known if the animals simply move to new locations. Roost disturbance seems to be an important factors, but there might be others, and there has been speculation that DDT might be a cause of population disappearances.

Conservation Actions [top]

Conservation Actions:	In South Africa, KwaZulu-Natal province they are protected from human disturbance. It might occur in some protected areas. Protection of nesting and roosting sites from disturbance is important.
