|Scientific Name:||Pipistrellus maderensis (Dobson, 1878)|
|Taxonomic Notes:||Unidentified Pipistrellus bats found in the Azores have recently been proposed to belong to this species, but this awaits confirmation.|
|Red List Category & Criteria:||Vulnerable C2a(i) ver 3.1|
|Assessor(s):||Alcaldé, J. & Juste, J.|
The species is restricted to few islands in the Canaries and the Madeira islands (and possibly the Azores). The population numbers < 1,000 individuals and it is suspected to be declining as a result of habitat loss, use of agricultural pesticides, and disturbance to roosts. This species is also severely fragmented. It is assessed as Vulnerable (VU C2a(i)) but may be approaching the Endangered category.
|Previously published Red List assessments:|
|Range Description:||This species is restricted to Madeira (Madeira, Porto Santo), and the western Canary Islands (La Palma, La Gomera, El Hierro, Tenerife). Pipistrelles found in the Azores (Santa Maria, Flores, Corvo, Graciosa, San Jorge) probably belong to this species. It is found from sea level to 2,150 m in the Canary Islands, although it prefers lowlands on Madeira (Fajardo and Benzal 1999).|
Native:Portugal (Madeira); Spain (Canary Is.)

|Population:||On Madeira and associated islands, it is abundant but very rare on Porto Santo. The total population is estimated to be less than 1,000 individuals, and trends are unknown (Rainho et al. 2002). On the Canary Islands it is relatively common and is the most frequently reported bat on all islands of occurrence, although no bat is abundant on the islands. Population size and trend have not been quantified (Trujillo 2002), although declines are suspected as a result of threats including loss and degradation of habitats, pesticide use, and disturbance and destruction of roosts. On the Azores, Pipistrellus bats are rare or very rare on all islands of occurrence, and the total number of individuals is probably less than 300 (Rainho et al. 2002).|
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||The Murciélago de Madeira (Pipistrellus maderensis) forages over a wide range of habitats, including aquatic habitats, woodland and farmland (Trujillo 2002). It feeds on flying insects, including small moths and Diptera. Breeding colonies have been found in crevices in sea-cliffs and underneath the roofs of houses, as well as in bird boxes (Trujillo 2002). Roost sites include rock crevices, bird boxes, and crevices in (often disused) buildings. It is often associated with human settlements, although in contrast with P. pipistrellus in mainland Spain it tends not to be found in parks, gardens, and tree-lined avenues in urban areas in the Canary islands (Trujillo 2002).|
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||5.2|
|Major Threat(s):||Restoration of buildings, covering cracks where it roosts, is a threat to the species. Rain-gauges attract dozens of bats which are trapped there and die (Trujillo 2007). Loss of natural habitat may be a threat, although the species is apparently adapted to man-made habitats. The use of agricultural pesticides may be a problem, and disturbance to roosts in buildings may also be of concern.|
|Conservation Actions:||The species is protected through Bern Convention, and included in Annex IV of EU Habitats & Species Directive. Rainho and Palmeirim (2002) proposed the following actions: identification, protection and monitoring of roosts; preservation and restoration of natural habitats, reduction of pesticide use; and, study of the species' biology, ecology, genetics, and systematics. Trujillo (2002) additionally recommend a public awareness campaign aimed at reducing disturbance of breeding colonies in private houses.|
