Amurum Forest Reserve (rocky outcrop)
Basic information
Sample name: Amurum Forest Reserve (rocky outcrop)

Reference: E. C. Nwankwo and S. A. Manu. 2016. Diversity and abundance survey of bat species in Amurum Forest Reserve north-central Nigeria. International Journal of Science and Engineering Investigations 5(59):98-103 [ER 2786]
Country: Nigeria
State: Plateau

Coordinate: 9° 53' N, 8° 59' E
Basis of coordinate: stated in text
Geography comments: the reserve "covers and area of about 300 hectares" and sampling was "in Amurum Forest Reserve and the surrounding area"
Habitat: tropical/subtropical savanna
Altered habitat: fragment
Protection: forest reserve
Substrate: ground surface
Habitat comments: "a few plant communities at various heights made up of trees and small woody plants"
the general area is heavily deforested based on satellite photos, so this is a fragment
Life forms: bats
Sampling methods: no design, mist nets
Sample size: 37
Years: 2014
Sampling comments: "Fieldwork was carried out between May and June, 2014... Two trapping stations of at least 100 m apart were established in each site. In each site, bats were captured using mist nets with a 36-mm mesh of 50-denier nylon (18 m long x 2 m high and 12 m long x 2 m high) and canopy mist net set up... In all, 54 independent capture stations were established with mist nets representing, at least, 1800 m2 of mist-net collecting surface operational for a total of 145 hours" across the four sites and "Nets were opened between 19:00 and 05:00 h at each site... bats comprising 9 species were recorded in 19 trap nights" (suggesting that sampling effort was uneven across sites)
