Geography
Country: Germany
State: Brandenburg
Coordinate: 52.9161° N, 14.1432° E
Coordinate basis: stated in text
Geography comments: "The study area at the southern border of Lower Oder Valley National Park (Lower Oder Valley), is located about 60 km northeast of Berlin"
Environment
Habitat: temperate broadleaf/mixed forest
Altered habitat: pasture
Protection: national/state park
Substrate: ground surface
Disturbance: grazing
MAT: 9.3
MAP: 589.0
Habitat comments: "The landscape developed at the end of the Weichselian Glaciation and is characterized by a mosaic of forests, freshwater bodies, arable land and grassland"
"The mean annual temperature measures about 9.3 °C and the average annual perception is 589 mm (distributed all over the year, with most rainfall during summer)"
"Grazing of livestock represents a significant management tool"
"Grazing systems can be distinguished between permanent and rotational grazing systems"
"A unique feature of the Lower Oder Valley National Park is the application of the concept of “naturalistic grazing” ... based on the idea that domesticated herbivores in part fulfil ecological functions of wild large herbivores that originally existed in this region"

Methods
Life forms: carnivores,ungulates
Sampling methods: line transect,automatic cameras
Sample size: 466 captures or sightings
Years: 2017
Days: 67
Nets or traps: 10
Net or trap nights: 670
Camera type: digital
Cameras paired: no
Trap spacing: 0.122
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.
For this particular study area, the study design was split, with 10 cameras recording in a "naturalistic grazing" area with livestock present, and 10 cameras recording in a neighbouring grassland area with no livestock present (Table 1; Fig. 2). Hence, only 10 camera traps were used to record the data entered here.
