Geoffroy’s (Cretzschmar’s) Horseshoe Bat

Rhinolophus clivosus  (Cretzschmar 1830) Geoffroy’s (Cretzschmar’s) Horseshoe Bat
Hebrew name: פרסף הנגב, parsaf hanegev

Order: Chiroptera
Family: Rhinolophidae

Global Threat: NE – Not Evaluated
Regional Threat: VU (B,D1) - Vulnerable

Distribution area: Only two breeding colonies are known, each with several dozen individuals.

Historic distribution: Harrison (1964) collected one specimen from the Negev Highlands and one specimen from a cave in the northwestern Negev (in Makin 1977). Makin (1977) reported a breeding colony with 70 bats from the Negev.

Typical Habitat: Deep caves (excavated and natural) in the Judean Desert and the Negev. Forages in areas with dense vegetation on the outskirts of water sources (Feldman 1998).

Threat and Disturbance Factors: Human visitors to roosting, breeding and wintering caves.

Population Size: The species’ distribution area in Israel extends over 8000 km2, but the population is very sparse. Isolated individuals can be observed at feeding sites.

Fluctuations in Population Size: The population is very sparse, and only one or a few individuals are found in most caves. In the 1990s a decrease was seen in the size of the colony observed by Makin in the Negev. There seems to be no significant change in the population size.

Isolation between Subpopulations: Unknown.

Necessary Steps for Species Preservation: Protecting caves with breeding colonies.
