Basic information
Sample name: Tli’ika

Reference: B. M. Wood, R. S. Millar, N. Wright, J. Baumgartner, H. Holmquist, and C. Kiffner. 2021. Hunter-Gatherers in context: Mammal community composition in a northern Tanzania landscape used by Hadza foragers and Datoga pastoralists. PLoS ONE 16(5):e0251076 [ER 3379]
Country: Tanzania

Coordinate: 3° 35' S, 35° 0' E
Basis of coordinate: based on nearby landmark
Geography comments: The research was carried out " in a geographic area southeast of Lake Eyasi (the basis of coordinate) in a sub-region known to the Hadza as Tli’ika"
"The area is hilly and ranges in elevation between 800–1400 meters"
Habitat: tropical/subtropical savanna
Altered habitat: inhabited area
Protection: unprotected
Substrate: ground surface
MAP: 500.0
Habitat comments: "The area is characterized by woodland savannah habitat"
"Annual rainfall averages ~500 mm with most rainfall concentrated in the months of December–April."
The area is "remote from agricultural villages and relatively unaffected by the migration, population growth, and agricultural development in other areas"
"This region continues to support the sustained presence of 200–400 Hadza community members who hunt mammals and birds using bows and arrows"
The area is "also occupied seasonally by Datoga pastoralists, who bring their livestock into Tli’ika during the dry season"
Life forms: carnivores, primates, rodents, ungulates, other large mammals, other small mammals
Sampling methods: automatic cameras
Sample size: 1575
Years: 2018
Days: 141
Nets or traps: 19
Net or trap nights: 2182
Camera type: digital
Cameras paired: no
Trap spacing: 2.000
Sampling comments: "A master grid was composed of 16 cameras spaced 2 km apart, and a sub-grid closer to the Hadza camp, composed of 4 cameras spaced 1 km apart"
Therefore, "a total of 20 camera traps (Bushnell Trophy Cam, infrared flash) were deployed ... onto suitably robust, mid to large-sized trees at a height of about 60 cm"
"At one site, cameras were repeatedly stolen and we did not obtain any data from this location"
"The 19 functioning camera traps operated for a range of 68–140 camera trap nights (69 to 141 camera trap days) from March 1 to July 21, 2018 with an average of 115 nights (116 days) per site. Cumulatively, a total of 2, 182 camera trap nights (2, 206 trap days) were collected"
"We set the cameras so that they would record a maximum of one picture per minute" and "we removed pictures of the same species that were taken within one hour of the initial picture of the same species prior to analysis to avoid pseudo-replications at each location"
