Sample name: Etosha Region

Reference: T. Rottstock, T. Göttert, and U. Zeller. 2020. Relatively undisturbed African savannas - an important reference for assessing wildlife responses to livestock grazing systems in European rangelands. Global Ecology and Conservation 23:e01124 [ER 3426]

Habitat: tropical/subtropical savanna

Altered habitat: pasture

Protection: national/state park

Substrate: ground surface

Disturbance: grazing

MAT: 24.0

MAP: 400.0

Habitat comments: "The semi-arid region receives average annual precipitation of only 250–400 mm, while the average annual temperature is above 22 °C" (24°C based on climate data for Etosha National Park)
"Riverbeds contain water only temporarily after rainfall, which can occur sporadically in summer months (November to April) with high inter-annual variability"
"The vegetation in this study area is characterized by mixed woodland savanna with partly open grasslands"
Acacia species and mopane are the dominate vegetation types
"The relatively poor soils only support low densities of livestock"
"Sedentary livestock farming is difficult in many parts of the country"
The study was "chosen to take place during the rainy season. However, owing to exceptional drought, there was no rain in Namibia during the study period"

Life forms: carnivores,ungulates

Sampling methods: line transect,automatic cameras

Sample size: 1464 captures or sightings

Years: 2019

Days: 76

Seasons: wet or monsoon

Nets or traps: 20

Net or trap nights: 711

Camera type: digital

Cameras paired: no

Trap spacing: 0.5

Sampling comments: "We deployed commercially available digital camera traps (Stealth Cam® G45NG PRO HD) with infrared sensor and infrared flash ... 20 of these camera traps were attached to wooden vegetation at about 1 m height"
"Camera traps were established in form of transects with uniform spacing"
"The distances between camera traps ... were identical"
"During period of data collection, camera traps operated 24 h per day, and took bursts of five photos with a delay of 30 s between trigger activations"
"Data was collected on a weekly basis"

Within the study area, comparisons were made between the data collected when livestock was present versus when livestock was absent. The register below corresponds to the data collected when livestock was absent.
