Ungulate substrate use in fauna passages

This dataset describes the substrate used by ungulates when crossing through fauna passages (n=7) in boreal Sweden and Finland, as well as the trajectories of the ungulates when crossing. Data of crossing events in the Excel file and the spatial maps are linked by the \"Count\" number. For each crossing event, date and time, any occurrence of snow, group size, and the animal´s direction of movement are given. As additional information, details of the seven fauna passages (location, dimensions, disturbances, and the monitoring period) are provided., We selected fauna passages for the study on the following criteria: i) minimum width 20 m and containing a variety of substrates (≥2) to allow animals to actively select substrate, ii) passage monitored for at least 1 year, iii) camera trap set up allowed equal (unbiased) coverage of the entire passage width. We monitored ungulates in the passages using motion-triggered cameras (Browning 2017 Spec Ops Advantage Trail in the Swedish passages, Uovision UM785-3G in the Finnish passages) with an infrared (IR) motion sensor, IR flash, and IR night vision. The trigger speed of cameras was 0.4 sec (Browning) or 0.6 sec (Uovision), cameras were set to rapid fire 3–5 images when being triggered, thereafter with a delay of 5 sec (Browning) or 60 sec (Uovision) to the next triggering. We mounted the cameras in the middle of the passages, at approximately 1 m above ground, attached to pre-existing fence poles or, in a few cases, new poles. We placed the cameras on one or both sides of the passage a..., # Ungulate substrate use in fauna passages

## Description of the data and file structure

We have submitted our data on ungulate crossing events through fauna passages (Ungulate_crossing_events_through_fauna_passages_Data.xlsx) and complemented with illustrations of trajectories of each crossing event (Ungulate_crossning_events_through_fauna_passages_Spatial_maps_of_trajectories.pdf). We also provide general info about the study sites (Ungulate_crossning_events_through_fauna_passages_General_info_of_fauna_passages.pdf).
