Geography
Country: Malaysia
State: Sarawak
Coordinate: 1.5533° N, 110.3592° E
Coordinate basis: stated in text
Geography comments: in "an oil palm plantation (20 360 ha) located between Bintulu and Miri... The first three sampling periods were conducted in HCV Fragment 1 while another three sampling periods were conducted afterwards in HCV Fragment 2"
Environment
Habitat: tropical/subtropical moist broadleaf forest
Altered habitat: plantation
Protection: unprotected
Substrate: ground surface
Habitat comments: "The surveys were conducted in the oil palm plantation (20 years old, planted in 1995) adjacent to two HCVF fragments (116.28 and 989.86 ha) with different topography and elevation (Figure 1). The smaller forest fragment (Fragment 1) is roughly 800 m wide by 1.5 km long. The larger forest fragment (Fragment 2) is a narrow (700 m wide) strip (14 km long) of steep forest (slope = 35°) with difficult access"
Methods
Life forms: birds
Sampling methods: no design,mist nets
Sample size: 126 individuals
Years: 2013 - 2015
Nets or traps: 7
Net or trap nights: 270
Sampling comments: "A total of six mist-netting sampling periods were conducted non-continuously from November 2013 to April 2015 in three ecotypes - the interior of forest fragments, the oil palm plantation, and the ecotone... In each sampling period, three transect lines were chosen and seven mist nets (9 m x 12.6 m, with 36 mm mesh) were set along each transect line to total 21 mist-nets per sampling period; one mist-net at the edge, and three each in the forest interior and in the adjacent oil palm plantation... A total of 22 680 net-hours were completed. Sampling effort was different at each HCV fragment; Fragment 1 was sampled for 9576 net-hours; Fragment 2 for 13 104 net-hours. Nets were open throughout day and night" and there were "45 sampling days" in total, actually meaning 945 net-days in total with 270 in forest, 135 in ecotones, and 270 in plantations
