Livestock activity shifts large herbivore temporal distributions to their crepuscular edges

# Livestock activity shifts large herbivore temporal distributions to their crepuscular edges Attached are csv files describing species occurrence in mara conservancy camera trap sites. The data has been pre-filtered for temporal independence by species occurring within the same 30-minute intervals. ## Description of the data and file structure **Mara_Filtered.csv** – List of mara conservancy image data filtered at 30-minute intervals for the same species for temporal independence. Data columns described as follows: · *Capture_id:* A unique identifier for each capture event and resultant image set. · *Park:* The name of the mara conservancy sampled: ENO (Enonkishu), OLC (Ol Choro), and LEM (Lemek). · *Season:* The numbered batch of images, ~1 year of data (ie: S1, S2, S3…). · *Site:* The unique alpha-numeric site code each camera trap site in the grid. · *Roll:* Unique identifier for each memory card swap (ie: R1, R2, R3…). · *Date:* The date stamp from the image is reported in yyyy-mm-dd. · *Time:* The time stamp from the image is reported in hh:mm:ss. Time zone is UTC + 3:00. Daylight savings time is not observed Kenya. · *Species*: Species of animal in the capture event. Multiple species in a single capture event are represented in separate rows. **Mara_Metadata.csv** – Camera site metadata, including habitat characteristics and distance to nearest points of interest. NA values indicate habitat metadata not recorded for that camera site. Data columns described as follows: · *Park:* The name of the mara conservancy sampled: ENO (Enonkishu), OLC (Ol Choro), and LEM (Lemek). · *Site_ID:* The unique alpha-numeric site code each camera trap site in the grid. · *Status:* Whether this is the current location of the camera site (current), an old location that has since been changed (moved), or the camera site has been permanently removed (pulled). · *Date:* Date that camera site was initially established. · *DD_Lat, DD_Long:* X and Y coordinates of the site (datum Arc1960, zone 36S) · *Habitat*: Classification of habitat at camera site (Grassland, Open Shrub, Dense Shrub, Forest). · *Shade:* Categorical ranking of shade over camera trap; 0-4 (4 highest). · *Vis_Mean:* Average Visibility at camera trap; rangefinders were placed 1.0 m above the ground and three readings were taken: one reading directly pointing out in front of the camera trap and two slightly angled to either side. · *Mean_TreeDist:* Averaged distance in meters to ten nearest trees; if no trees are present, we used “1500 meters”. · *Road:* Distance in meters of camera trap to nearest paved road. · *Trail:* Distance in meters of camera trap to nearest trail. · *Settlement:* Distance in meters of camera trap to nearest settlement. · *Water:* Distance in meters of camera trap to nearest body of water (dam, stream, river). ## Sharing/Access information Files above include Mara conservancy data only.
